Q

A patient who is taking a statin drug to treat dyslipidemia has begun a diet and exercise program. The patient reports new onset of muscle pain several weeks after beginning therapy. What is the initial action by the provider?

A. Discontinue the statin drug immediately

B. Obtain a creatine kinase level

C. Prescribe acetaminophen or ibuprofen

D. Recommend reducing exercise intensity

A

B. Obtain a creatine kinase level

A potential serious side effect of statin drugs is drug-induced myopathy. Patients who report new-onset muscle pain should have creatine kinase levels evaluated. If this is elevated, the drug should be stopped, and renal function should be evaluated. It is not safe to assume that the muscle pain is related to the exercise until CK levels are determined.

Q

A 13-year-old Native American female has a body mass index (BMI) at the 90th percentile for age. The primary care pediatric nurse practitioner notes the presence of a hyperpigmented velvet-like rash in skin folds. The child denies polydipsia (abnormally great thirst), polyphagia (excessive eating), and polyuria (excessive urination). The nurse practitioner will take what action?

A. Counsel the child to lose weight to prevent type 2 diabetes

B. Diagnose type 2 diabetes if the child has a random glucose of 180 mg/dL

C. Order a fasting blood sample for a metabolic screen for type 2 diabetes

D. Refer the child to a pediatric endocrinologist

A

C. Order a fasting blood sample for a metabolic screen for type 2 diabetes

This child has three risk factors for type 2 diabetes: Native American ethnicity, overweight, and acanthosis nigricans (a skin condition that causes a dark discoloration in body folds and creases). The PNP should perform metabolic screening on a fasting blood sample to diagnose this. Lifestyle changes may be necessary to control the disease if diagnosed, but this child may already have the disease, and management options aren’t clear until the diagnosis is made. Diagnosis is based on a random glucose >200 mg/dL. It is not necessary to refer this child until a diagnosis is made.

Q

Elevated blood pressure in response to stress (especially in the doctor’s office) is called “white-coat hypertension.”

Which of the following statements is true about white-coat hypertension?
(select all)

A. As long as the majority of blood pressure readings are normal, the patient does not require treatment because there is no increased risk of adverse cardiac outcomes.

B. Patients with white-coat hypertension have an intermediate risk for adverse outcomes when compared with patients with normal blood pressure and those with chronically elevated blood pressure.

C. White-coat hypertension is more common in young patients.

D. Patients with white-coat hypertension have an elevated left ventricular mass when compared to patients with normal blood pressures.

A

Both B & D

B. Patients with white-coat hypertension have an intermediate risk for adverse outcomes when compared with patients with normal blood pressure and those with chronically elevated blood pressure.

D. Patients with white-coat hypertension have an elevated left ventricular mass when compared to patients with normal blood pressures.

Patients with white coat hypertension have outcomes that are intermediate between normotensive and hypertensive patients. In addition, they have an elevated left ventricular mass. Surprisingly, white coat hypertension is more common in the elderly.

Q

A 35-year-old male presents to the office with upper respiratory symptoms. He is taking no medications except for a bit of pseudoephedrine for his cold. You notice when looking at his vital signs that his blood pressure is 180/106 mm Hg. Repeat measurement confirms that the blood pressure is elevated at 175/105 mm Hg.

A. Start a chronic antihypertensive since he is at risk for a stroke within the next couple of days with a blood pressure at this level.

B. Administer clonidine in the office to reduce the blood pressure to a safe level of about 150/100 mm Hg.

C. Watch the patient over the next two weeks and get additional blood pressure readings before deciding what to do and instruct him to discontinue pseudoephedrine.

D. Schedule the patient for outpatient labs and electro-cardiogram.

E. Fire the patient from your practice. He’s messing up your quality measures.

A

C. Watch the patient over the next two weeks and get additional blood pressure readings before deciding what to do and instruct him to discontinue pseudoephedrine.

The diagnosis of hypertension requires two elevated blood pressures on two different occasions. This patient’s elevated blood pressure could be situational, related to decongestants and current illness (though decongestants only increase systolic blood pressure by 2–3 mm Hg if at all). Neither “A” nor “B” is correct because a blood pressure of 175/105 mm Hg does not pose a risk of acute stroke, and the pressure need not be lowered acutely unless there is evidence of end-organ injury (e.g., angina, heart failure, hypertensive encephalopathy). “D” is incorrect because you cannot definitively establish that this patient has hypertension based on only one in office blood pressure measurement. As for “E”…really? Is this why we went into medicine?

Q

The ambulatory blood pressure monitor reveals that the patient’s blood pressure is >140/90 mm Hg more than 40% of the time, indicating that he is indeed hypertensive.

The initial evaluation of the hypertension includes the following:

A. History, physical, CBC, urinalysis, glucose, BUN, creatinine, electrolytes, ECG, and lipids

B. History, physical, CBC, uric acid, glucose, BUN, creatinine, electrolytes, and lipids

C. History, physical, CBC, urinalysis, glucose, BUN, creatinine, electrolytes, ECG, lipids, and echocardiography

D. History, physical, and labs only as indicated by history and physical

A

A. History, physical, CBC, urinalysis, glucose, BUN, creatinine, electrolytes, ECG, and lipids

History, physical, CBC, urinalysis, glucose, BUN, creatinine, electrolytes, ECG, and lipids are the generally agreed-upon initial workup of the hypertensive patient. “C” includes echocardiography, which is not recommended as part of the routine evaluation but may be indicated if signs of cardiac disease are present.

Q

You start a 35-year-old male on chlorthalidone for hypertension, but his blood pressure does not respond at a dose of 12.5 mg/day (have your patients cut the 25-mg tabs in half). His blood pressure on follow-up is 148/96 mm Hg.

A. Push his chlorthalidone to 25 mg daily before starting another medication

B. Stop the chlorthalidone and start another medication

C. Rely on exercise and diet to normalize the blood pressure

D. Start a second drug , before, you have maximized the dose of the first drug

E. Start a workup for secondary causes of hypertension

F. A or D

A

F. A or D
A. Push his chlorthalidone to 25 mg daily before starting another medication
D. Start a second drug , before, you have maximized the dose of the first drug

Per the JNC 8 guidelines, both “A” and “D” are acceptable strategies; you could push up the dose of a first drug or add a second drug. There is a lack of randomized controlled trials to guide these recommendations. JNC 8 urges us to tailor therapy based on individual circumstances, clinician and patient preference, and drug tolerability. Low-dose chlorthalidone (12.5 mg) provides the greatest blood pressure reduction per mg of drug, and there is little clinical benefit of utilizing >25 mg daily of HCTZ or chlorthalidone. Higher doses are associated with increased adverse effects with minimal clinical gain in hypertension management. “B” is incorrect because a patient with this level of blood pressure elevation will generally require more than one drug to achieve a normalized blood pressure. “C” is incorrect because the majority of patients are unable to maintain an adequate diet or exercise regimen to effectively treat blood pressure. Exercise and dietary change are certainly laudable goals and should be encouraged in all patients. However, they are not likely to normalize blood pressure in most hypertensive patients. “D” is also correct as it represents one of the acceptable JNC 8 guideline strategies to dose antihypertensive drugs. “E” is incorrect since this patient has not yet proven to be resistant to treatment.

Q

The patient returns to your office with blood pressures measured six times over a period of two weeks at a local pharmacy. Only three of the six readings suggest that the patient is hypertensive. The patient states that the elevated blood pressures were while he was under stress at work.

A. Start an antihypertensive

B. Send the patient for a 24-hour ambulatory blood pressure measurement

C. Don’t worry about the blood pressure since half of the readings were within a normal range

D. Get a nephrology consult to help in decision making

A

B. Send the patient for a 24-hour ambulatory blood pressure measurement

One way to determine if a patient with contradictory readings is hypertensive is to perform 24-hour ambulatory blood pressure monitoring. This can be useful in patients who have elevated blood pressures in the office but not at home or vice versa. It can also be used if you do not trust the blood pressure readings taken outside of your office. “A” is incorrect since we have not yet established that this patient is hypertensive. “C” is incorrect since we have not yet established that this patient is not hypertensive. “D” is incorrect because you are smarter than that and should be able to work through this kind of case yourself!

Q

A patient wonders which popular diet she should use to lose weight.

You let her know that the most effective popular diet is:

A. Low carbohydrate (Atkins diet)

B. Low fat (Ornish diet)

C. Low glycemic load diet (Zone diet)

D. High protein (Paleo diet)

E. No one particular diet is more effective than others for weight loss. The key to success is choosing a diet that you can maintain.

A

E. No one particular diet is more effective than others for weight loss. The key to success is choosing a diet that you can maintain.

Any diet you can stick to seems to work. There does not seem to be any advantage to one diet over another for weight loss (except for making the proprietors wealthy). For example, Weight Watchers may have a bit better success because of peer pressure, weekly meetings, and motivational techniques (BMJ. 2011;343:d6500). But any diet that you can maintain long-term will work. Of note, the common belief that maintaining a 3,500 calorie weekly deficit will result in 1 lb (0.45 kg) of weight loss per week is a myth. But reducing calorie intake by 100 calories per day may lead to a gradual weight loss of approximately 10 lb over 1 to 3 years (Am Fam Physician. 2015;91(9):634–638).

Q

As your patient is not meeting with an ounce of success (literally), you engage in a discussion about weight loss pharmacotherapy.

A. Levothyroxine (Synthroid, Levoxyl)

B. Methylphenidate (Ritalin)

C. Orlistat, (Xenical, Alli)

D. Paroxetine (Paxil)

A

C. Orlistat, (Xenical, Alli)

Drug therapy is considered appropriate as an add-on to lifestyle management for people with a BMI of 30 kg/m2 or greater, or a BMI of 27 kg/m2 or more who already have a comorbid condition such as diabetes, hypertension, or hyperlipidemia. Of the choices listed, only orlistat is indicated by the FDA to treat obesity (more below). “A” and “B” are incorrect. Although patients treated with these medications might lose weight as a side effect, obesity alone is not an indication for levothyroxine or methylphenidate. Paroxetine (“D”) may be associated with weight gain and is not indicated for obesity.

Q

After collecting a history and physical, which of the following is the most appropriate next step in the evaluation of weight gain in a 30 year-old obese female?

A. Refer for a sleep study

B. Check urinary free cortisol level

C. Draw blood for thyroid-stimulating hormone level

D. Evaluation for adrenal adenoma causing Cushing disease

E. Cast your gaze down, realizing that affecting behavior change is difficult

A

C. Draw blood for thyroid-stimulating hormone level

Because of her obesity, this patient is also at risk for sleep apnea, diabetes, hypertension, and hyperlipidemia. These concerns will need to be addressed. However, her chief complaint is weight gain, which could certainly be due to an underlying disease. Although in most overweight patients a cause for weight gain is not found, the physician is obligated to search for potentially treatable causes of weight gain, including hypothyroidism. The symptoms of hypothyroidism are often nonspecific and include weight gain and fatigue. That said, an exhaustive search for underlying causes of obesity is not required for the vast majority of patients. History, exam, and limited laboratory evaluation should be sufficient for most patients.

Q

A new patient presents for his annual examination and has some questions about cardiovascular disease risk. He also wants to chat about his favorite sports team (Iowa Hawkeyes, we hope), but you gently steer him back to the matter at hand.

The following are all considered cardiac risk factors when calculating cardiac risk and the need for statins per the ACC/AHA calculator (http://www.cvriskcalculator.com), except:

A. Age

B. A relative with early heart disease

C. Smoking

D. Hypertension

E. Gender

A

B. A relative with early heart disease

The ACC/AHA calculator includes the following risk factors for CAD: age, gender, “race,” total cholesterol, HDL cholesterol, systolic and diastolic BP, diabetes, smoking and whether or not one is being treated for hypertension. Unlike many Caribbean resort destinations, the calculator is not all-inclusive. Many known risk factors for heart disease (e.g., family history, obesity) are not taken into account. The risk calculator is a tool; you must continue to apply clinical judgment. Also, the calculator, as well as the entire guideline, is not meant to be used to manage all forms of dyslipidemias. Remember from earlier in this chapter that peripheral vascular disease is considered a CAD equivalent.

Q

You obtain laboratory tests. The patient has normal electrolytes and the following cholesterol panel: Total cholesterol 175 mg/dL, LDL 110 mg/dL, HDL 35 mg/dL, and triglycerides 150 mg/dL. He is a 55-year-old African-American male, nonsmoker, and nondiabetic who takes no medications. His systolic blood pressure is 132/85 mm Hg. You plug all his data into the ASCVD risk calculator and generate a 10-year ASCVD risk of 7.5%.

Given the ASCVD risk you calculated, and being consistent with the 2018 ACC/AHA guideline, you recommend:

A. No changes, keep calm and carry on

B. A treadmill stress test

C. A high fiber diet

D. Low-intensity statin therapy (e.g., simvastatin 10 mg daily)

E. Moderate-intensity statin therapy (e.g., atorvastatin 10–20 mg daily)

A

E. Moderate-intensity statin therapy (e.g., atorvastatin 10–20 mg daily)

Did you think this patient was a candidate for moderate statin therapy prior to this guideline? If not, you are not alone. The 2018 ACC/AHA guideline has changed the way we determine risk, expanding the use of statins. Patients whose 10-year ASCVD risk is 7.5% or greater should be on moderate-to-high-intensity statin therapy. As noted above, we have dueling guidelines. Of course, you should discuss the pros and cons with every patient.

Q

Your astute patient appears to be goal-oriented and asks you what his target LDL should be. You reply:

A. “Targets are so 2012. The goal is to get you on a moderate-to-high-intensity statin. There is no specific LDL goal number.”

B. “Your target LDL is <100 mg/dL.”

C. “Your target LDL is about 70 mg/dL.”

D. “Your target LDL is simply as low as we can get without causing rhabdomyolysis…well, maybe just a little rhabdo would be OK.”

A

A. “Targets are so 2012. The goal is to get you on a moderate-to-high-intensity statin. There is no specific LDL goal number.”

The 2018 ACC/AHA guideline does not recommend treating to specific LDL targets. Instead, appropriate statin therapy should be selected based on risk category as previously indicated. Your goal is to get the patient to a maximal dose of statin and not a specific LDL. That said, the LDL should be reduced by 50% even if that is a starting point of 400 mg/dL and the patient ends up at 200 mg/dL.

Q

According to the 2018 ACC/AHA Blood Cholesterol Guideline, all of the following automatically qualify as patients who would benefit from statin therapy except:

A. A patient with known cardiovascular disease

B. A 40-year-old patient with an LDL of 200 mg/dL

C. A 55-year-old diabetic patient with an LDL of 130 mg/dL

D. A 55-year-old nondiabetic patient without known cardiovascular disease whose 10-year ASCVD risk is calculated as 10%

E. A 35-year-old smoker with hypertension

A

E. A 35-year-old smoker with hypertension

The 35-year-old patient might be a candidate for a statin (HMG-CoA reductase inhibitor) but is not an automatic candidate based on the information given. All other options describe patients who would benefit from statin therapy according to the 2018 ACC/AHA guideline. The 2018 ACC/AHA guideline relies on a risk calculator for primary prevention. See Table 2-11 for a summary of the 2018 cholesterol guidelines. It is important to note that while the ACC/AHA guideline recommends moderate-to-high-intensity statin therapy starting at a 10-year ASCVD risk score of 7.5%, the USPSTF recommends low-to-moderate dose statin therapy at an ASCVD risk score of 10%. We cannot know for sure what answer the ABFM would use for the test, but they usually side with the USPSTF.

What does the USPSTF recommend in terms of screening for lipid disorders?

B. Screen men age 35 years and older

C. Screen women age 45 years and older

D. Universal screening of all patients age 40 to 75

A

D. Universal screening of all patients age 40 to 75

USPSTF updated its lipid testing recommendations in 2016. Here is a summary:

Screen patients 40 to 75 years of age without CAD. Treatment is suggested for those 40 to 75 years of age with elevated lipids and one other risk factor for CAD (risk factors for this purpose include (LDL-C > 130 mg/dL or HDL-C < 40 mg/dL), diabetes, hypertension, and smoking) and >10% ten-year risk of having a cardiac event based on the ACA calculator.

Use low-to-moderate dose statins. For those with a risk of 7.5% to 10%, discuss pros and cons with the patient—which of course you do with all patients anyway (JAMA. 2016;316(19):1997–2007). Note that the benefit of lipid treatment outweighs the risk of diabetes (which can be seen with statins).

Q

The patient then asks you about something he read about “crap.” A light bulb goes off and you realize he wants to know about C-reactive protein (CRP).

Which of the following best represents the role of CRP in cardiac disease in 2015?

A. CRP should be measured in all patients in whom cardiac disease is suspected

B. CRP should be measured only in patients with intermediate cardiac risk factors (e.g., those with a 10-year risk of CAD of 10–20%)

C. CRP should be measured in patients with known heart disease in order to monitor inflammation and risk

D. CRP should be measured in low-risk (<10% risk of CAD in next 10 years) patients who have no known cardiac disease. An elevated CRP suggests that these patients should be treated with a lipid-lowering therapy

E. CRP has not been shown to be useful and does not contribute significantly to cardiac risk stratification

A

E. CRP has not been shown to be useful and does not contribute significantly to cardiac risk stratification

Although, high-sensitivity CRP (hsCRP) was initially thought to be a possible biomarker for cardiac risk assessment, it has been shown to be of marginal benefit. The use of hsCRP led to minimal reclassification of patients (a maximum of 11% of intermediate patients were reclassified in one study). The Class IIa recommendation to use hsCRP was published by the AHA in 2003, prior to further studies that have questioned its usefulness.

Q

You advise your patient to start atorvastatin 20 mg daily. You check baseline transaminases, which are normal. When your patient returns 3 months later and sees your partner (because you took a “vacation” to study for the board examination), she checks his lipids and transaminases out of habit. If only you had been there! You know that the FDA no longer recommends periodic liver enzyme testing while on a statin. Statin-related hepatotoxicity is an idiosyncratic reaction that is extremely rare and completely unpredictable, so there is no point in routinely checking transaminases. Well, your partner didn’t get the memo, and you return to find your patient’s ALT and AST have both doubled while on atorvastatin and are now almost twice the upper limit of normal for your lab.

When you find transaminases are twice the upper limit of normal while on a statin, the proper response is to:

A
Stop the statin because of the elevated liver enzymes

 B
Start a different statin since this is not a “class effect”

C
Continue the statin and consider other causes for the elevated liver enzymes

D
Add cholestyramine to help ease the burden on the liver

E
Refer for liver biopsy to rule out other causes of elevated liver enzymes

A

C
Continue the statin and consider other causes for the elevated liver enzymes

Statins can be continued as long as the elevation of liver enzymes is less than three times the upper limit of normal. Never assume that this is a drug effect if there is a reason to believe that the patient could have another disease, such as hepatitis C.

You are compelled to perform the requisite history and physical examination to assess for other causes of liver disease. In the course of your investigations, other labs and imaging may be in order. However, liver biopsy (“E”) would be taking your fiduciary duty to the extreme. “A” is incorrect since the levels are only two times the upper limit of normal. “B” is incorrect for two reasons. First, there is no need to act to change the drug at this point. Second, elevated liver enzymes are a class effect. “D” is incorrect because you do not need to add another drug at this time, and cholestyramine will do nothing to “ease the burden on the liver,” whatever that means.

Q

After a thorough history, examination, appropriate lab and imaging tests, you determine that the liver enzyme elevation was due to fatty infiltration. A month later the enzymes have come down to the upper limits of normal. When you see your patient back, he complains of pain and tenderness in his legs, shoulders and back. He also reports generalized fatigue and weakness.

What is the most appropriate next step in the evaluation and management of this complaint?

A
Stop his atorvastatin and replace it with rosuvastatin

B
Double the dose of atorvastatin

C
Check liver enzymes

D
Check creatine phosphokinase (CPK) level

E
Start coenzyme-Q10 (ubiquinone)

A

D
Check creatine phosphokinase (CPK) level

This patient is presenting with symptoms that may be attributable to statin-induced myopathy. Statins have been associated with myalgia and rhabdomyolysis. Prior to making any decisions about therapy, the next step would be to confirm your suspicions by checking the CPK level. If this patient has statin-induced muscle symptoms, he is unlikely to improve by switching to rosuvastatin (“A”); hence, increasing the statin dose (“B”) is the wrong thing to do. While it may be reasonable to check liver enzymes (“C”) due to his complaint of fatigue, myopathy is more likely, given his constellation of symptoms. Of course, in your real medical practice, you could order liver enzymes and CPK, but an examination is not real life! Finally, “E” is incorrect. Coenzyme Q10 has not been shown to prevent or treat statin-related myopathy (Mayo Clin Proc. 2015;90:24). But vitamin D may be useful in patients who are deficient.

Q

You check a CPK level, and it is … normal. Darn. You thought you had this mystery wrapped up.

From this normal CPK, you can conclude that:

A
He does not have statin-induced myopathy since the CPK is within normal limits

B
His fatigue and aches are a manifestation of depression and sleep disturbance

C
You can safely increase the dose of his statin

D
He still may have statin-induced myopathy despite a normal CPK

E
Your lab has a serious quality control issue

A

D
He still may have statin-induced myopathy despite a normal CPK

He still may have statin-induced myopathy despite a normal CPK, so “A” is incorrect. There are several crossover trials that demonstrate myopathy in patients with normal muscle enzymes. The mechanism is thought to be a mitochondrial dysfunction. “B” is incorrect, and the reverse may actually be true (myopathy causing poor sleep and anhedonia). “C” is incorrect because he may indeed have a myopathy, and a trial off one or both drugs is warranted. Remember that gemfibrozil (and less so fenofibrate), which you might prescribe for hypertriglyceridemia, interact with statins to increase the risk of statin-induced myopathy/rhabdomyolysis. Remember also that there is no evidence that treating with gemfibrozil or fenofibrate improves cardiovascular outcomes.

Q

You stop his atorvastatin. A few weeks later, he returns and feels great! You consider starting a different agent to treat his lipids.

B and C: Colestipol & Colesevelam

Ezetimibe (Zetia) is not a bile acid sequestrant but rather reduces cholesterol absorption by blocking at the brush border of the small intestine. This is a mechanism that is different from any of the other lipid-lowering agents. It is relatively safe but expensive and less potent than the statins. You could also try pravastatin and fluvastatin, which are less likely to cause myopathy.

Side effects of ezetimibe include which of the following?

A
Diarrhea

B
Arthralgia

C
Angioedema

D
Liver enzyme elevation

E
All of the above

A

E
All of the above

“C” deserves special mention. As with ACE inhibitors, angioedema has been reported with the use of ezetimibe during post-marketing research. The rate of occurrence is not known. However, it can be life-threatening although no deaths have been reported to date. All of the other side effects are known to occur at a rate greater than with placebo.

Q

Your patient is now OK taking maximal dose of a statin, but he has questions about a “cholesterol shot” his friend is taking. Apparently, his friend’s LDL is 300—kind of high. You assume that he is talking about a PCSK9 (proprotein convertase subtilisin kexin type 9) inhibitor, which prevents the binding and the degrading of LDL receptors (thus, there are more LDL receptors to uptake LDL from the blood).

The indications for the use of a PCSK9 inhibitor (Praluent® [alirocumab] and Repatha® [evolocumab]) in a patient on statins includes which of the following?

A
Ongoing angina regardless of the percent decrease of LDL on a maximal dose of a statin

B
Less than a 50% reduction from baseline of LDL after maximal dose statin + ezetimibe

C
An absolute LDL of >190 mg/dL after maximal dose statin regardless of the starting LDL

D
A cardiovascular event while on a maximal dose statin plus a bile acid sequestrant

A

B
Less than a 50% reduction from baseline of LDL after maximal dose statin + ezetimibe

Indications for the use of a PCSK9 inhibitor include the following: (1) Failure to reduce the baseline LDL by 50% on a maximal dose of a statin andezetimibe, or (2) a patient who has a cardiovascular event while on a statin plusezetimibeand an LDL of ≥50 mg/dL (not a bile acid sequestrant as in “D”), or a very high LDL secondary to familial hypercholesterolemia. These drugs are expensive (>$10,000/year), and prevent one cardiovascular even for every 74 patients treated for 2 years.

Q

A 15-year-old pale Caucasian female returns for her annual well-child check and sports physical. She is well-known to your clinic, and over the years she has steadily gained weight. Her parents and a younger sibling are overweight, and now she has become obese by measure of the pediatric BMI percentages. In recent years, you have become more diligent with watching the BMI on her growth curve. She is aware of her weight problem yet has not voiced any plan for attempting weight loss.

What defines “obesity” in adolescence?

A. A BMI in the 85th to 94th percentile for age-sex-and-height-specific measures

B. A BMI ≥95th percentile for age-sex-and-height-specific measures

C. The child has the appearance of being heavy

D. The child complains of being fat or overweight

E. BMI >35 kg/m2

A

B. A BMI ≥95th percentile for age-sex-and-height-specific measures

A BMI at or above the 95th percentile is considered “obese.” A BMI in the range of 85th to 94th percentiles is considered “overweight.” The use of BMI allows for an objective measure, and although not perfect, can give a picture on the growth curve to patients and parents where they stand relative to age-sex-and-height-related norms. Strict BMI numbers (as in “E”) are not applicable to children and adolescents. A subjective concern about weight (“D”) is important but does not necessarily always warrant further evaluation.

Q

Her obesity is discussed openly during the office visit. As expected, she is ashamed and embarrassed about her weight gain. She admits to not knowing what to do and she asks if anything can be done to quickly lose weight.

Which of these medications would you recommend now as a first-line therapy for weight loss?

A. Topiramate (Topamax)

B. Bupropion (Wellbutrin)

C. Orlistat, (Xenical)

D. Metformin (Glucophage)

E. None of the above

A

E. None of the above

No medication is approved for children or adolescents as a first-line therapy. Antidepressants are not helpful if used primarily for weight loss. If there is comorbid depression, which is more common in obese children, a “weight loss” or “weight neutral” antidepressant may be appropriate. Antiepileptic medications have not proven helpful. Metformin has been used for weight loss in children but is not approved by FDA and has only small effect on weight with unclear clinical significance. Orlistat is approved for children age 12 and older; however, the benefits are limited to 2 to 3 kg of weight loss. Side effects are often intolerable and include loose, oily stools and stool urgency (just mention the phrase “fecal incontinence” to a teenager and see how far you get). Experts agree that orlistat is only appropriate for adolescents with comorbidities caused by obesity. Obesity (“bariatric”)surgery (especially Roux-en-Y and gastric sleeve) is being performed more often on adolescents and is effective at reversing metabolic changes (insulin resistance, hypertryglyceridemia, etc.). It also improves sleep apnea and depression and improves quality of life.

Q

Her BMI is now at the 97th percentile, having jumped from the 86th percentile last year. What additional workup should be considered?

A. Fasting plasma glucose level or hemoglobin A1c

B. Fasting lipids

C. Renal function testing with BUN and creatinine

D. Liver function testing with ALT

E. All of the above

A

E. All of the above

Expert opinion suggests that once a child reaches a BMI at the 85th to 94th percentiles, a lipid panel and a fasting glucose or A1c should be obtained to evaluate for hyperlipidemia and early onset type 2 diabetes. When the BMI reaches the 95th percentile, renal function and blood pressure should be monitored, and liver function should be checked (for fatty liver). Fatty liver disease is possible at an early age and is reversible if weight loss can be achieved. Close attention to family history is essential. If family members are obese or have obesity-related comorbidities, early intervention and evaluation are even more crucial. For females who have started menses, it is important to assess for any changes in menstrual patterns.

Q

Which of the following is NOT a recommended early childhood intervention to prevent and/or treat obesity?

A. Encouraging breastfeeding

B. Decreasing screen time of electronic devices

C. Planning fewer family meals

D. Restricting calories from sweets and fast foods

E. Improving efforts for exercise and outdoor activity

A

C. Planning fewer family meals

Helping with food preparation and sitting down as a family for meals can lead to consumption of more nutritious and lower caloric dense foods. Breastfeeding can lead to protection against obesity even into the teenage years. Formal recommendations suggest limiting TV, tablet, phone, computer use, and video games to less than 2 hours per day with minimal screen time for children under age 2. Fast food, sweets, and desserts need to be limited to small servings or few servings per week. Finally, at least 60 minutes of exercise should be encouraged every day—doing a variety of activities will keep children more engaged and interested.

Q

During the examination of the patient, you notice acne, some coarse facial hair, and dark skin pigmentation around the base of her neck.

What is another finding you may expect to see with further questions and tests?

A. Normal menses

B. Low free testosterone level

C. Low DHEA sulfate (DHEA-S)

D. Hypoglycemia

E. Abnormal hypothalamic–pituitary axis hormones

A

E. Abnormal hypothalamic–pituitary axis hormones

While the earliest clinical manifestation is irregular menses, she is showing other signs of possible polycystic ovarian syndrome (PCOS). This can be associated with elevated prolactin, low TSH, and a marked elevation of FSH relative to luteinizing hormone (LH). PCOS can be associated with early menarche, dysmenorrhea, and amenorrhea. A pregnancy test should be done in any case of amenorrhea. PCOS is also associated with elevations of testosterone, DHEA-S, and androstenedione. If there are other significant physical examination findings such as elevated blood pressure, purple striae, and a “buffalo hump,” consider testing for Cushing syndrome. See chapter 15 for more on PCOS.

Q

A 13-year-old Native American female has a body mass index (BMI) at the 90th percentile for age. The primary care pediatric nurse practitioner notes the presence of a hyperpigmented velvet-like rash in skin folds. The child denies polydipsia, polyphagia, and polyuria. The nurse practitioner will take what action?

A. Counsel the child to lose weight to prevent type 2 diabetes

B. Diagnose type 2 diabetes if the child has a random glucose of 180 mg/dL

C. Order a fasting blood sample for a metabolic screen for type 2 diabetes

D. Refer the child to a pediatric endocrinologist

A

C. Order a fasting blood sample for a metabolic screen for type 2 diabetes

This child has three risk factors for type 2 diabetes: Native American ethnicity, overweight, and acanthosis nigricans. The PNP should perform metabolic screening on a fasting blood sample to diagnose this. Lifestyle changes may be necessary to control the disease if diagnosed, but this child may already have the disease, and management options aren’t clear until the diagnosis is made. Diagnosis is based on a random glucose >200 mg/dL. It is not necessary to refer this child until a diagnosis is made.

Q

A 6-year-old child has a systolic blood pressure between the 95th and 99th percentile for age, sex, and height, and a diastolic blood pressure between the 90th and the 95th percentile on three separate clinic visits. This child’s blood pressure is placed in which classification?

A. Normotensive

B. Pre-hypertensive

C. Stage 1 hypertensive

D. Stage 2 hypertensive

A

C. Stage 1 hypertensive

Stage 1 hypertensive pressure ranges from the 95th percentile or from 120/80 mm Hg to 5 mm Hg above the 99th percentile for age, sex, and height for either systolic or diastolic pressure. Normotensive pressure is below the 90th percentile. Pre-hypertensive pressure is between the 90th and 95th percentiles. Stage 2 hypertensive pressure is greater than the 99th percentile.

A 12-year-old child whose weight and body mass index (BMI) are in the 75th percentile has a diastolic blood pressure that is between the 95th and 99th percentiles for age, sex, and height on three separate occasions. Which test will be prescribed for this child initially?

A. Complete blood count

B. Erythrocyte sedimentation rate

C. Renal function

D. Urinalysis and electrolytes

A

C. Renal function

Since the majority of children with stage 1 or 2 hypertension have renal or renovascular causes for elevated BP, renal function and plasma renin tests should be performed. Children under 10 years of age with stage 2 hypertension should have more aggressive laboratory evaluation, including CBC, ESR, UA, and electrolytes.

Q

A 12-year-old child whose body mass index (BMI) is greater than the 95th percentile has a blood pressure at the 98th percentile for age, sex, and height. After lifestyle changes that include diet and exercise, the child’s BMI drops to the 90th percentile, but the blood pressure remains the same. What is the primary care pediatric nurse practitioner’s next step in treating this child?

A. Continued close monitoring of blood pressure

B. Ordering an echocardiogram

C. Prescribing an ACE inhibitor medication

D. Referral to a nephrologist or cardiologist

A

D. Referral to a nephrologist or cardiologist

Children who have persistent BP elevation after lifestyle changes are made should be referred to a nephrologist or cardiologist who has experience using antihypertensive agents in children. The specialist orders necessary tests and medications, not the primary care provider.

ADA recommendations for DM screening

A

Adults of any age who are overweight/obese (BMI > 25; > 23 Asians)
AND another RF:
- First-degree relative with diabetes
- High-risk race/ethnicity (e.g., African American, Latino, Native American, Asian
American, Pacific Islander)
- History of CVD
- Hypertension (>140/90 mmHg or on therapy for hypertension)
- HDL cholesterol level <35 mg/dL (0.90 mmol/L) and/or a triglyceride level >250 mg/dL
(2.82 mmol/L)
- Women with polycystic ovary syndrome
- Physical inactivity
- Other clinical conditions associated with insulin resistance (e.g., severe obesity,
acanthosis nigricans)

Patients with prediabetes (A1C >5.7% [39 mmol/mol], IGT, or IFG) should be tested yearly.

Women who were diagnosed with GDM should have lifelong testing at least every 3 years.

For all other patients, testing should begin at age 35 years.

If results are normal, testing should be repeated at a minimum of 3-year intervals, with
consideration of more frequent testing depending on initial results and risk status.

A. non productive

cough is typically dry and non productive. Bradykinin is partly degraded by ACE, degradation and conversions of angiotensin 1 to angiotensin II by ACE occurs in lung. when degradation is impaired, bradykinin can accumulate and cough can ensure

can happen at any time of day, can start at any time within 2 weeks or 1 year later

Greatest incidence of HTN is in older adults r/t changes in intima of vessels as aging and calcium deposition occur. Males of any age are more likely to be hypertensive than F in same age. African Americans have highest incidence in general population.

85
Q

A 50 y.o. pt with HTN has taken HCTZ 25mg daily for the past 4 weeks. Her BP has decreased from 155/95 to 145/90. How should the NP proceed?

A. Wait another 4 weeks before making a dosing change

B. Increase HCTZ to 50mg daily

C. Add a drug from another class to the daily 25mg HCTZ

D. Stop the HCTZ and start a drug from a different class

A

C. Add a drug from another class to the daily 25mg HCTZ

The recommended target BP is < 140/90. The current plan has not allowed this patient to meet this goal, so it is not acceptable to continue this current dose. Increasing the HCTZ to 50mg/daily will NOT result in a decrease in BP, only an increase in K loss. Adding a drug from another med class is a good choice because the combined effects of antihypertensive medication nearly always produce a decrease in BP and both drugs can be maintained in low doses to minimize side effects. 
Thiazides are most effective in combo with ACEI
86
Q

 Apnea (OSA)
 Aldosteronism (Primary hyperaldosteronism)
 Bruits (Renovascular disease such as renal artery stenosis or fibromuscular dysplasia)
 Bad parenchymal disease (Chronic kidney disease)
 Catecholamines (Pheochromocytoma, other catecholamine release situations,
decongestants, herbal preparations)
 Coarctation of the aorta
 Cushing’s syndrome and other excess glucocorticoid states
 Drug induced or related (see Table 2 of the Onusko article
 Diet (excess of sodium, alcohol, black licorice)
 Erythropoietin excess (exogenous or secondary to COPD/polycythemia)
 Endocrine disorders (not already listed): hypothyroidism, hyperthyroidism,
hyperparathyroidism, pregnancy-induced hypertension, pheochromocytoma, acromegaly

88

Angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme (ACE) inhibitors are designated as pregnancy category “X” and may cause congenital abnormalities, especially in the second and third trimester.
Calcium channel blockers such as nifedipine and beta blockers such as labetalol are preferred for the treatment of hypertension in pregnant women. Diuretics, such as thiazide diuretics, may be used with caution in pregnant women but may increase the risk of maternal volume loss.

Q

A 52-year-old man presents to your office for a health maintenance exam, and initial vital signs show a blood pressure of 154/94 mm Hg. Previous blood pressure measurements were normal. What is the next step in management?

a. Start an antihypertensive medication
b. Repeat the blood pressure measurement
c. Look for causes of secondary hypertension
d. Perform a urine drug screen

A

b. Repeat the blood pressure measurement

If the initial blood pressure measurement is elevated, it should be repeated. The diagnosis of hypertension is based on the average of two or more properly measured blood pressure values over two or more visits. It would be incorrect to start an antihypertensive medication after the first measurement of an elevated blood pressure. While it is important to consider secondary causes of hypertension, the diagnosis of hypertension must first be made by repeating the blood pressure measurement and recording multiple instances of elevated blood pressure. While a urine drug screen may be helpful in the search for substances that may cause elevated blood pressure (such as cocaine and methamphetamine), the elevated blood pressure measurement should first be repeated before any other workup is undertaken.

92
Q

Which of the following statements is correct regarding blood pressure evaluation?

a. The patient should be lying quietly on the exam table for 5 minutes prior to obtaining a blood pressure measurement.
b. Arm should be below heart level during blood pressure measurement.
c. The bladder of the blood pressure cuff should encircle 80% of the forearm.

d. Hypertension can be diagnosed by the average of two elevated blood pressure
readings on a single occasion.

A

c. The bladder of the blood pressure cuff should encircle 80% of the forearm.

It is essential to use the correct blood pressure cuff size in the assessment of blood pressure, as cuffs that are too large or small will give incorrect values. The bladder of the blood pressure cuff should encircle 80% of the forearm. The patient should be sitting upright quietly for 5 minutes prior to obtaining a blood pressure measurement. The arm should be supported and held at heart level. Use an average of more than two readings on two separate occasions to assess an individual’s blood pressure.

93
Q

Which of the following antihypertensive medications should be avoided in patients with gout?

a. Losartan
b. Hydrocholorthiazide
c. Nifedipine
d. Atenolol

A

b. Hydrocholorthiazide

Thiazide diuretics such as hydrochlorothiazide and loop diuretics such as furosemide may increase blood uric acid levels, thereby increasing the risk of gouty flares. Calcium channel blockers (CCBs) and the angiotensin II receptor blocker (ARB) losartan may decrease the incidence of gouty flares. Beta blockers such as atenolol are not associated with increased risk of gout flares.

94
Q

Which of the following antihypertensive medications should be avoided in patients with poorly controlled asthma?

a. Losartan
b. Hydrochlorothiazide
c. Nifedipine
d. Atenolol

A

d. Atenolol

Beta blockers such as atenolol may cause bronchoconstriction in patients with asthma. Diuretics such as hydrochlorothiazide, calcium channel blockers such as nifedipine, and angiotensin II receptor blockers such as losartan can be used to treat hypertension in patients with asthma.

95
Q

Which of the following antihypertensive medications should not be used as a first-line treatment for a person with essential hypertension and no other medical conditions?

a. ACE Inhibitor
b. Beta Blocker
c. Calcium channel blocker
d. Diuretic (thiazide diuretic)

A

b. Beta Blocker

According to the 2017 American College of Cardiology (ACC) guidelines and the 2014 Joint National Committee (JNC) guidelines, thiazide diuretics or calcium channel blockers are generally considered first-line options for therapy in all persons with hypertension. ACE inhibitors and angiotensin receptor blockers (ARBs) are also recommended as options in non- black patients. This is a departure from prior recommendations when ACE inhibitors and ARBs were routinely recommended as first-line therapy for Caucasian patients. Beta blockers (unless there are other factors such as a history of coronary artery disease or cardiac arrhythmias) are not recommended for routine first-line therapy of essential hypertension.

96
Q

Which of the following medications should be discontinued in a woman with essential hypertension who is trying to get pregnant?

a. Methyldopa
b. Labetalol
c. Nifedipine
d. Losartan

A

d. Losartan

ACE inhibitors and ARBs are a pregnancy class D (known to cause fetal abnormalities). Losartan, an ARB, should be discontinued in a woman who is trying to get pregnant. Methyldopa (antiadrenergic), labetalol (beta blocker), and nifedipine (calcium channel blocker) are preferred medications for chronic hypertension in pregnancy. These medications are characterized as pregnancy class C (risk cannot be ruled out) although they have no known association with congenital abnormalities but may cause neonatal hypotension.

97
Q

ACC/AHA guidelines (2018), who are the individuals most likely to benefit from starting on a statin therapy?

A

Statin therapy is recommended for:
 Patients with clinical atherosclerotic cardiovascular disease (ASCVD) - either a high- intensity statin, or the maximally tolerated dose of a statin
 Patients with severe primary hypercholsterolmia (LDL > 190 mg/dL) regardless of their 10-year ASCVD risk – high dose statin
 Patients age 40-75 years with diabetes and LDL > 70 mg/dL – start moderate-intensity statin (no (need to calculate the 10-year ASCVD risk)

Statin therapy should be considered in:
 Patients age 40-75 years without diabetes and LDL > 70 mg/dL and a 10-yeaer ASCVD risk ≥7.5% - consider treatment with a moderate-intensity statin.

Other agents?
 Patients at very high-risk for ASCVD with a LDL > 70 mg/dL – consider addition of ezetimibe if LDL > 100 mg/dL

98
Q

According to the 2018 ACC/AHA lipid guidelines, are there any specific LDL treatment goals?

A

No. Rather than treating to a specific LDL cholesterol (e.g., <70 mg/dL) and/or non-HDL cholesterol treatment target, the appropriate intensity of statin therapy is targeted to reduce the ASCVD risk in patients who are likely to benefit.

In general, high-intensity statin therapy is designed to lower LDL by ≥50%, moderate-intensity statin therapy by 30-49%, and low-intensity statin therapy by <30%.

99
Q

Statin cautions/contradinications

A

Contraindication - pregnancy, cholestatic liver dx

Caution - active liver dx, transaminitis

100
Q

Side effects statins

A

102
Q

A 45-year-old woman with a BMI of 33 kg/m2 comes to primary care clinic for her annual physical exam. She does not smoke and does not have diabetes. She has no family history of early CAD. She is not fasting today, but cannot easily return for a fasting lipid profile. Her TC is 148 mg/dL, TG is 523 mg/dL, HDL is 47 mg/dL, and LDL was not able to be calculated because TG is greater than 400 mg/dL. The direct LDL was 53 mg/dL. Because of the patient’s hypertriglyceridemia and obesity, you advise her to adopt a low-fat, low cholesterol diet, increase her physical activity, and follow up for a fasting lipid profile in 6 months. After rigorous diet and exercise efforts, she returns to clinic. Her BMI is 28 kg/m2. Repeat labs are: TC = 144 mg/dL, TG = 267 mg/dL, HDL = 40 mg/dL and LDL = 51 mg/dL.

Does she warrant drug treatment for a dyslipidemia?

A

No. The 2018 ACC/AHA guidelines do not specifically address treating elevations in the triglycerides. It is suggested that elevated triglycerides (greater than 500 mg/dL) prompt consideration of other secondary causes of hyperlipidemia, including diet, certain drugs, nephrotic syndrome, chronic renal failure, lipodystrophies, poorly controlled diabetes, hypothyroidism, obesity, and pregnancy.1
She has limited other cardiovascular risk factors identified. She could likely continue to benefit from a high fiber (10 to 25 g/day), low cholesterol (less than 200 mg/day) diet, with less than 7% of calories from saturated fat. It could also be prudent to advise her to increase her physical activity and work on weight reduction.

103
Q

Screening for dyslipidemia in children

A

universal screening for dyslipidemia should occur once between ages 9 and 11 years and once between ages 17 and 21

targeted screening in children between the ages of 2 and 8 years of age

Children (ages 2-8) should also have a fasting lipid profile checked twice (with averaged results used to make treatment decisions):
 Children with a parent, grandparent, aunt/uncle, or sibling with myocardial infarction (MI), angina, stroke, or coronary artery bypass graft (CABG)/stent/angioplasty when younger than 55 years in males and 65 years in females
 Any child with a parent who has a TC greater than 240 mg/dL or known dyslipidemia
 Any child with diabetes, hypertension, BMI greater than 95th percentile or who smokes
cigarettes

 Any child who has one of the following moderate- or high-risk medical conditions:

o High Risk
 Type 1 or type 2 diabetes mellitus
 Chronic kidney disease, end-stage renal disease (ESRD), history of renal transplant
 History of orthotopic heart transplant
 Kawasaki disease with current aneurysms

o Moderate Risk
 Kawasaki disease with regressed coronary aneurysms
 Chronic inflammatory disease (systemic lupus erythematosus, juvenile
rheumatoid arthritis)
 HIV infection
 Nephrotic syndrome
 Note: The USPSTF gives lipid screening in children and adolescents an
“I” recommendation (“I” = insufficient evidence) and were last updated in August, 2016.8 This illustrates some of the controversy that has surrounded universal screening in children. Regardless, both Bright Futures and the 2018 ACC/AHA lipid guidelines recommend universal screening between ages 9-11 years and 17-21 years of age.1

104
Q

Abnormal lipid profile management in children < 10 y.o.

A

weight loss
increased physical activity
nutritonal counseling

-reduced-fat dairy products of > 1 y.o.

evaluation and treatment of dyslipidemias in children has not been adequately studied nor shown to have a similar benefit that was demonstrated in adults. Subsequently, it has been noted by the USPSTF that the adverse effects of both lipid-lowering drugs and low-fat diets have not been adequately evaluated in children. In addition, there have been concerns about increased anxiety in screened children and adolescents.

105
Q

Abnormal lipid profile management in children >/= 10 y.o.

A

Elevated LDL cholesterol levels, a cholesterol lowering medication “should be considered.”

106
Q

Which of the following lab values are the most likely to be affected by eating within an hour of lab draw?

a. Direct low-density lipoproteins (LDL)
b. Total LDL
c. Triglycerides
d. High-density lipoprotein (HDL)

A

c. Triglycerides

Triglyceride values are the most likely to be affected by eating within an hour of blood being drawn. The total LDL and HDL values are usually not affected by eating. While the calculated LDL measure (Total Cholesterol - HDL – [TG / 5]) is affected by eating (as it uses the triglyceride measurement in the calculation), the direct LDL value is not affected by eating.

107
Q

What is the mechanism of action of ezetimibe?

a. Inhibits 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase
b. Inhibits cholesterol absorption at the brush border of the small intestine
c. Activates a nuclear transcription factor that regulates lipid metabolism
d. Acts as a resin to bind cholesterol and prevent absorption from the digestive tract

A

b. Inhibits cholesterol absorption at the brush border of the small intestine

Ezetimibe blocks absorption of cholesterol in the brush border of the small intestine. Statins such as atorvastatin and pravastatin are HMG-CoA reductase inhibitors, thereby limiting the rate of hepatic cholesterol synthesis and leading to increased peripheral LDL receptor expression and LDL uptake from the blood. Fibrates such as gemfibrozil activate peroxisome proliferator- activated receptor alpha (PPAR-alpha), a nuclear transcription factor that regulates lipid metabolism, and are used in the treatment of severe hypertriglyceridemia. Bile acid sequestrants, such as cholestyramine and colestipol, are resins that bind cholesterol in the gastrointestinal tract and increase cholesterol excretion in the stool.

108
Q

According to the 2018 American College of Cardiology / American Heart Association (ACC/AHA) guidelines, which of the following patients should receive statin therapy?

a. A patient with a 15% ten-year risk of development of atherosclerotic cardiovascular disease
b. A patient with type 1 diabetes mellitus and an LDL cholesterol of 90 mg/dL
c. A patient with LDL cholesterol greater than or equal to 200 mg/dL
d. All of the above

A

d. All of the above

According to experimental data with high-quality evidence, the following four groups of individuals have been shown to benefit from treatment with HMG-CoA (3-hydroxy-3-methyl- glutaryl-coenzyme A) reductase inhibitors (statins): 1) persons who already have atherosclerotic cardiovascular disease (ASCVD); 2) those who are likely to have greater than or equal to 7.5% risk of development of ASCVD within the next decade; 3) persons with diabetes mellitus (type 1 or type 2) who have an LDL cholesterol greater than or equal to 70 mg/dL and 4) persons with an LDL cholesterol greater than or equal to 190 mg/dL.

116
Q

A patient taking atorvastatin for newly diagnosed dyslipidemia complains of fatigue, weakness, and muscle aches in his lower back, arms, and legs for the past 3 days. It has not improved with rest. How should this be evaluated?

A. Stop the atorvastatin immediately

B. Check liver enzymes first

C. Order a CPK level

D. Ask about nighttime muscle cramps

A

A. Stop atorvastatin immediately

The complaints highly suggest rhabdomyolysis. The atorvastatin should be stopped immediately and a CPK should be ordered. Liver enzymes would not assess for the etiology of myalgias. They asses tolerance to statins in liver. Nighttime muscle cramps are not usually associated with statin use. Myalgias are common but not typically associated with elevated CPK. Rhabdo is a rare side effect of statins.
