A. Hypokalemia
B. Hypernatremia
C. Hyperkalemia
D. Hypocalcemia

A

C. Hyperkalemia

Do not use ACE inhibitors in combination with ARBs or direct renin inhibitors d/t increased risk of hyperkalemia especially in patients with chronic kidney disease or those on potassium supplements or potassium sparing drugs. there is also risk for acute renal failure in patient with severe bilateral artery stenosis.

Q

A patient with chronic kidney disease stage 3 has been recently diagnosed with hypertension. First-line pharmacologic treatment includes which of the following agents?
A. Metoprolol
B. Lisinopril
C. Nifedipine
D. Terazosin

A

B. Lisinopril

First line therapy for adults with hypertension and CKD stage 3 or higher or stage 1 with albuminuria or elevated albumin-to-creatinine ratio is an ACE inhibitor or an ARB if an ACE is not tolerated.

102
Q

Which micronutrient should an individual with primary hypertension increase in their diet?
A. Calcium
B. Chloride
C. Potassium
D. Sodium

A

C. Potassium

Individuals with primary htn should increase potassium aiming for 3500 to 5000 mg/d preferably from dietary sources.

Foods high in potassium (avocados, sweet potatoes (yams), coconut water, bananas, oranges, watermelon, cantaloupe, honeydew, apricots, grapefruit, dark leafy vegetables (spinach, broccoli), and edamame (boiled soybeans).

103
Q

After antihypertensive therapy is initiated, a patient’s blood pressure should be rechecked after how many months?
A. 1
B. 2
C. 3
D. 4

A

A. 1 monthq

104
Q

An older adult male patient who is a smoker is newly diagnosed with primary htn. He has a history of emphysema and second-degree AV block. HIs blood pressure from the previous visit is 145/80 mmHg. During the current visit, his blood pressure is 155/80 mmHg. What is the next step?
A. Start the patient on atenolol (Tenormin) 50mg once a day and reassess in 3 months.
B. Start patient on felodipine (Cabren) 2.5mg once a day and reassess in 2 months
C. Start patient on chlorthalidone (thalitone) 12.5mg daily and reassess in 1 month.
D. Nothing; no action or treatment is needed at this time.

A

C. Start the patient on chlorthalidone (thalitone) 12.5mg daily and reassess in 1 month

105
Q

What blood pressure medication should be avoided in patients with emphysema?

A

Beta blockers such as atenolol (tenormin) cannot be used.

106
Q

What blood pressure medication is contraindicated in patients with second degree AV block?

A

Calcium channel blockers such as felodipine (Cabren).

107
Q

Which of the following is a risk enhancing factor for atherosclerotic cardiovascular disease?
A. Acute kidney injury
B. Low-density lipoprotein cholesterol greater than 140 mg/dL
C. Menopause
D. C-reactive protein (CRP) of 2.0 mg/L or greater

A

D. C-reactive protein (CRP) of 2.0 mg/L or greater

Risk enhancing ASCVD includes CRP of >/= 2.0 mg/L, CK disease (not acute injury), persistently elevated LDL-C levels of 160 or greater, history of preeclampsia or premature menopause, metabolic syndrome, family history of early ASCVD, Ankle brachial index less than or equal to 0.9 and high risk ethnicity.
