Exam 4 Flashcards by Callie Wanek

Most common cause of cardiovascular disease
Definitions:
Abnormal accumulation of fatty substances and fibrous tissues in the blood vessel walls
This reduces blood flow to the heart muscle
-Heart works heart to get blood through narrow artery and BP goes up

Fatty lipids deposited in the arterial wall –> inflammatory response –> injury to the endothelium

Atherosclerosis

Non modifiable:
-Age 
--Men >45 years old

-Race
--African Americans, Mexican Americans, Native -Americans, Asian Americans
-Family history: even in healthy so major prevention
Modifiable
-Diabetes

-High blood cholesterol
New risk factors:
-Peridontal disease, influenza, sleep apnea (OSA: hypoxia --> heart disease; causes HTN --> artherscelorsis), increased BMI (increased abdominal girth increases risk of atherosclerosis)
For a diagnosis of metabolic syndrome: need 3 or more
-Insulin resistance
-Abdominal obesity
-Dyslipidemia
-Hypertension
-Proinflammatory state (HIGH LEVELS OF CRP)
-Prothrombotic state (HIGH FIBRINOGEN)
So DMT2

Ischemia-inadequate blood supply that deprives the heart muscle of oxygen
Angina-chest pain due to ischemia
Myocardial infarction-if the decrease in blood supply is enough or for a long enough duration –> death of myocardial cells
Myocardial damage  decreased cardiac output!!
Could lead to heart failure and sudden cardiac death due to lethal cardiac rhythm disturbances r/t increase workload on heart –> disturbed electrical pathways

Chest pain
Shortness of breath (especially in elderly)
Extreme fatigue
Diaphoresis
Nausea and vomiting
Women are atypical: shoulder/arm pain, jaw/back pain

How do you know the difference between angina and MI? = Angina isn’t consistent pain and goes away with meds and rest; MI is persistent pain

Controlling cholesterol

High cholesterol=CAD
Four elements of fat metabolism
-Total cholesterol
-LDL - bad: want them to go to liver to be excreted
-HDL - good: makes LDL go to liver
-Triglycerides
-*these all affect the development of heart disease

20 yrs and older: fasting lipid panels every 5 years
under 20 with family history: tests frequently

Hypertension:

Risk of CAD increases with HTN
Increases workload of left ventricle –> stressed left ventricle –> failing

Diabetes:
-Dyslipidemia
-Increased platelet aggregation
-Altered red blood cell function
What do all of these lead to?  = thrombus/clot which increases risk of CAD

Pain or pressure in the anterior chest
Caused by insufficient blood flow (usually a blocked artery)
-Oxygen demand exceeds the supply
Types of angina:
-Stable: occurs with exhortation and relieved with rest - happens with activity
-Unstable: lasts longer, more severe, can occur with rest
-Intractable/refractory: severe, incapacitating
-Variant/Prinzmetal’s: chest pain, pain at rest, ST elevation with EKF so take to cath lab and will have clean vessels/no blockage: this is vasospasm r/t ST elevation
-Silent: ischemia on EKG but no pain

12 lead EKG
Blood biomarkers: usually drawn q 8 hrs 3 times and look for peak
-CK/CKMB, Myoglobin, Troponin T* or Troponin I* (shouldn’t have any; if + it’s released in response to ___Tegrity* and leads to ischemia)
Stress test: treadmill or meds to increases HR
Nuclear scan
Cardiac catheterization: visualization (pt has chest pain, do card cath in femoral/radial artery, thread cath and visualize arteries/vessels for blockages; use dye, so worry about kidney function r/t contrast dye)

Normotension:
-Blood pressure <120/80
-Must look at this on a continuum
-Assessment is based on the average of at least 2 readings
--longer BP and higher it gets on trend --> increased risk of morbidity and mortality 
Prehypertension
-Blood pressure 120-139/80-89
-Lifestyle changes: exercise, no smoke/drink, eat healthy
- time to catch and fix it
Hypertension stage 1:
-Blood pressure 140-159/90-99
-Lifestyle changes and medication
Hypertension stage 2:
-Blood pressure 160 or higher/100 or higher

Multifactoral
Age (44) and Elderly (noncompliant; kidney/liver have decreased function, so start low and increase slow)
More common in younger men than women until menopause
Obesity - Childhood
Often coexists with dyslipidemia, diabetes mellitus, sedentary lifestyle and metabolic syndrome (increase risk of CVD with all)
African Americans-especially males
Oral contraceptive use-when accompanied with smoking & obesity

Increased sympathetic nervous system activity
Increased absorption of sodium, chloride, and water (heart failure and increased extracellular fluid –> overwork heart –> big/boggy heart –> fails
Increased extracellular fluid volume, increased systemic vascular resistance

Weight reduction DASH diet-dietary approaches to stop hypertension -Eating plan: consistent amount of potassium, low sodium, high protein, fruit/veggie, low bad fat Sodium restriction Physical activity 30 mins at least 3X/week Moderate alcohol consumption (1-2/day for men; 1/day for women) Smoking cessation Complimentary and alternative therapies (stress reduction: yoga, acupuncture, herbal meds but watch med interactions and do lots of teaching) Self management: self monitor/manage at home, self diet/exercise, good teaching from nurse

nursing management of HTN

``` Must support patient in adherence/compliance! do everything you can to do so Most patients need 2 drugs Thiazide diuretics -Hydrochlorothiazide (K wasting), Furosemide (K wasting), spironolactone (K sparing) Beta Blockers -Atenolol, Metoprolol, Propranolol Alpha2-Agonists -Clonidine: longer acting Vasodilators: dilate blood vessels to lower BP - Hydralazine, Nitropursside, Nitroglycerin ACE inhibitors -Captropril, Enalapril, Lisinopril ARB -Losartan, Valsartan CA channel blockers -Diltazem, Amlodipine ``` Can reduce when BP is <140/90 for at least 1 year, so self monitor at home and bring log to apts. *Give simplest treatment possible Don't stop taking r/t rebound HTN

pharm therapy for HTN

Blood pressure >180/>120 Poorly controlled HTN or stopped taking meds More common in men, older adults, African Americans Head injury, pheochromocytoma, food-drug interactions, eclampsia, substance abuse, renal disease 2 categories Hypertensive urgency -Blood pressure is severely elevated but there is no evidence of organ damage* -Elevated blood pressure with severe headaches, epistaxis, anxiety -*Goal-reduce bp to 160/110 for several hours to several days Hypertensive emergency - Blood pressure >180/120 and must be lowered quickly to stop organ damage - Hypertension of pregnancy - MI - Dissecting aortic aneurysm - Intracranial hemorrhage - Can’t lower too quickly r/t pass out r/t decreased perfusion

hypertensive crisis

Blood vessel grafted to occluded coronary artery Indications: Alleviation of angina that can’t be controlled Left main coronary artery stenosis, multi vessel CAD Prevention & treatment of MI, arrhythmias, heart failure (blocks coronary artery and decreases blood and O2 --> tissue death; the increases work load stresses the heart) Treatment of complications from unsuccessful PCI

coronary artery bypass graft (CABG) | open heart surgery

General anesthesia Cardiopulmonary bypass machine (some on pump, some off pump) Blood vessel from somewhere else (saphenous vein, left internal mammary artery-LIMA) is grafted-bypasses the obstruction Chest tubes - anytime with open heart; drains stuff from surgery; 2-3 tubes Pacer wires: in heart, externally stick out of skin; if brady/tachy you can hook up to this connection MIDCAB: minimally invasive CABG with no chest incision

CABG

MI: common intra/post op from CABG; inta can decrease perfusion so it can decrease O2 to area in heart -Know post op if they had an MI during surgery by doing EKG Renal failure: decrease perfusion to kidneys - check I/O, output, labs BUN/Creatinine to check for decrease perfusion Hypovolemia: most common cause of decreased CO after CABG -Know if they have it if their tachy/hypotensive and give fluids/blood to fill tank back up Bleeding: can cause platelet dysfunction; have low hematocrit/hemoglobin, low BP, blood in chest tube r/t internal bleed - do good chest tube assessments and monitor pleura bag Cardiac tamponade: emergency; fluid around pericardiac sac - not a problem if you have a chest tube Fluid overload Hypothermia: keep warm postop to prevent vasoconstriction; cold will constrict vessel Hypertension: with vasoconstriction; worry about pressure on heart and can rupture/bleed - give antihypertensives Tachyarrhythmias: a fib on 3rd day r/t volume changes in body (fluid imbalances) Bradycardias: pace monitor Heart failure: increased work load on heart

CABG complications

Neurological status-LOC, pupils: decreased perfusion during surgery (stroke r/t clots and hyperperfusion) - hard post op to assess r/t pain meds so know baseline* Cardiac-heart rate, rhythm, sounds: higher HR the more decreased in CO; a fib is common; hypervolemia will have S3 sound Pulmonary-Lung sounds, O2 saturations, respiratory rate, rhythm: note work of breathing; ex: pneumonia r/t alveoli collapse - hear crackles and know why it happened and fix the why Peripheral vascular status-pulses, color, skin temp, edema: take vessel and bypass so check blood flow, pulse and perfusion Renal-urine output, labs to see decrease perfusion Fluid & electrolyte-I/O, skin turgor Pain-assessment: *know baseline and pts. goal - do frequent vitals and control. In pain, they can't wait/deep breath/incentive spirometer Assess lines, tubes: chest tube, IV, pacer wires - hard to ambulate because of this - must be done

nursing care assessment for CABG

Restoring cardiac output: hypovolemia is most common cause, so give fluids/blood-give back what they lost - watch output, labs, VS, check for a fib (r/t blood pooling) and arrhythmias - watch mental status change to check perfusion to brain Maintaining adequate tissue perfusion: ambulate early, watch CSM, peripheral vascular, DVT/clots* Monitor signs/symptoms of infection: take temp, labs, watch incision site Fluid and electrolyte imbalance: I/O, labs Hourly blood sugar for 1st 4 hours. If >150-180 start insulin drip to bring glucose down. Glucose control is very important for healing* Impaired gas exchange: cough/deep breath/IS 10X/hour, give O2, on vent for 1st hour, pain control, assess lungs Impaired cerebral circulation: monitor neuro status* Pain: can't have good gas exchange if they don't have good pain control

nursing interventions for CABG

Reduced blood flow Unstable angina-plaque ruptures, artery not completely occluded Acute coronary syndrome Vasospasm: with prinsometals/variant angina r/t vasospam; see ST elevation Decreased oxygen supply from blood loss (r/t decrease perfusion/tissue death) or hypotension (not enough O2 in body) Increased oxygen demand from tachycardia, drugs (cocaine) IMBALANCE BETWEEN OXYGEN SUPPLY AND DEMAND!

Myocardial infarction (MI) Types: STEMI: 100% occlusion NSTEMI: partial occlusion Q wave: can show MI

Chest pain- can be persistent/sudden or sometimes silent! **EKG-T wave inverted, ST segment elevation, Q wave Echocardiogram: ultra sound of heart to look at heart function; if MI see abnormal LV wall function -r/t lack of O2 --> cell death --> abnormal wall movement Labs: 1. Triponin (draw 3x/8 hours-look for peak and find downhill slide), 2. CKMB, 3. Myoglobin

manifestations of MI

``` Chest pain Shortness of breath, pulmonary edema Nausea and vomiting Decreased urine output Cool, clammy, diaphoretic skin, pale Anxiety, restlessness *Fear *Denial ```

clinical manifestations of MI

``` Get to the hospital! give good education, like don't drive EKG Labs *Oxygen r/t chest pain and no O2 Nitroglycerin to dilate vessels Aspirin in case of clot Beta blocker decrease BP/work of heart Ace/ARB to decrease BP ```

medical treatment of MI

``` Evaluate need to PCI: do you need cath lab? determine this off labs/EKG if theres ST elevation Thrombolytics Morphine to decrease work of heart IV Heparin, Enoxaparin - anticoag Clopidigrel - antiplatelet Bedrest to decrease work on heart ```

medical management of MI

Education about risk reduction 3 phases-starts with diagnosis of atherosclerosis and continues for months! Look at page 421, box 14-7 for health promotion education-KNOW THIS!!

cardiac rehabilitation

``` Relieve pain PCI Aspirin, Nitroglycerin, Beta blockers Anticoagulants Morphine Oxygen *Reduce anxiety Close monitoring MONA ``` ``` Monitor and report changes in the cardiac rhythm and rate closely Heart sounds* Lung sounds * Blood pressure* Pain* Respiratory status* ```

nursing management of MI

Function of the Kidney

1. Filature out waste 2. Regulates BP by fluid balance 3. RBC production 4. Electrolyte imbalances r/t fluid balance

Sudden Can happen in hours to days Oliguria = <400 mL/day (20 mL/hr) anuria = no U.O. 50 mL/day Increased serum BUN/CR = waste in the blood Acidosis: S/S: blow off = resp system compensates and have increased RR and uremic smell Fluid excess- lungs 1st AMB dyspnea/crackles, then in tissues (edema/periorbital/JVD) Electrolyte imbalance: potassium is biggest concern - will increase w/o kidney BP irregularities: FVE hypertension and RAS system (kidney and blood have renin and active by vasoconstriction and can't rid waste and holds onto fluid) Anemia: RBC regulation in kidney - w/o kidney = low hemoglobin/hematocrit

acute renal failure

Exact patho isn’t always known Different categories Prerenal: perfusion problem/blood flow to area; determined by MAP (average pressure blood pumps with each cycle - measures perfusion and needs to be >65) Intrarenal Postrenal

acute renal failure patho

``` Caused by any condition in which there is Decreased blood flow (MAP <65) Decreased cardiac output -MI - heart is compromised -Shock - heart is compromised -Heart failure - heart is compromised Hypovolemia: not enough fluid that can't support pressure -Dehydration -Hemorrhage -GI disturbances: colitis or diarrhea -Sepsis: drops BP ```

prerenal of ARF

Persistent hypoperfusion (low perfusion) --> decreased adaptation --> increases sympathetic response --> arteriole constriction --> decreases GFR --> acute renal failure (ARF) If addressed early, no actual nephron damage/recovery can be rapid Prolonged prerenal AR --> leads to intrarenal ARF  increased mortality

prerenal of ARF

Direct insult on renal tissue Causes -Acute tubular necrosis (ATN) * (90% of intrarenal cases) --Nephrotoxic agents --Medications: contrast dye (hard on vessels of kidneys), antibiotics r/t filtered in kidneys (vancomyocin) --Rhabodmyolysis: muscle wasting - proteins released from break down and go to kidneys and they can't filter --Severe transfusion reactions --Prolonged prerenal ARF Infections --Crush injuries: r/t rhabodmyolysis and break down of muscles and proteins released

intrarenal of ARF

Obstruction in the urinary tract below the kidneys causes waste to build up in the kidneys (occurs after it leaves filtration system) Hydronephrosis --> GFR decreases Causes - Obstruction-BPH (benign prostetic hypertrophy - blocks urethra) or kidney stones - Obstructed foley catheter kinked

postrenal of ARF

Prerenal: give fluids r/t low volume - support pressure with meds (vasosuppressors) intrarenal: stop giving med if that's the cause, change abx if that's the cause - allow kidney to rest Postrenal: break up the stones with shock waves, put in stent to hold area open, nephrotube, ilioconduct - remove prostate if that's the issue

interventions of ARF | fix issue/cause

Initiation Oliguric Diuretic Recovery

phases of acute renal failure

Renal insult to cell injury Can last hours to days -MVA: physical injury can start it BP: no BP can start it Manifestations - GFR decreased - Decreasing UOP - Alterations in fluid volume - -Imbalance in I&O* - -Increased weight

initiation phase of ARF

<400ml UOP/24 hrs. (20 mL/hr) Lasts 1-2 weeks Manifestations - Electrolyte imbalance: low phosp, low calcium, high K, high Na, high BUN/CR, FVE, azotenia = build up of waste products - Increased BUN/CR - Fluid volume imbalance NEED TO SUPPORT THE KIDNEYS! Help do their job - watch electrolytes/give meds, change diet, fluid restrict May need dialysis Longer in this phase --> worse prognosis (want out of phase as fast as possible)

oliguric phase | main acute injury phase

Recovery of function and continues/lasts 7-14 days Gradual increase in urine output Manifestations - *Polyuria-nephrons still not fully functional-excretes waste but not able to concentrate urine - frequent/larger amount urine (more dilute/lighter) - Gradual decrease in BUN/CR r/t removal of waste Monitor for hypovolemia rebound: restrict so much they don't have enough

diuretic phase when urine output starts to increase the glomerular filtration has start to recover

Improvement of renal function Can take up to 12 months normal function but continue to watch kidney

recovery phase of ARF

``` Lethargy/ fatigue - esp with dialysis Decreased urine output -Oliguria (<400ml/day) -Anuria (<50ml/day) Nausea/Vomiting r/t GI upset/anorexia Hyperventilation r/t acidosis/trying to block off CO2 --> fast smelly respirations Diagnostic tests -Increased BUN/CR -Increased Phos/decreased -Ca++ (treat phos 1st) -Anemia: look at blood test -Hyperkalemia: dangerous; EKG changes, muscle cramps/weakness, diarrhea -EKG-peaked T waves r/t hyperkalemia -Metabolic acidosis ```

S/S acute renal failure

``` Identify and correct cause Maintain perfusion to kidneys Clear obstructions: catheter? stone? Treat shock/infection: antibiotic Diuretics: give with FVE IV fluids: to maintain fluid balance, BP and perfusion to kidneys Dialysis ```

management of ARF

Assessment -Respiratory -Cardiovascular Frequent I/O to check what phase pt. is in Daily weight Fluid restriction: give hard candy to stimulate secretions, ice chips, measure liquid for them - can get FVE, damage to kidneys/heart/electrolyte imbalance Teaching: importance and readmission Turn, cough, deep breathe to prevent fluid in lungs/edema Prevent infection -CAUTI

nursing management of ARF

Monitor labs Hyperkalemia -Kayexalate: binds to K and rids through feces: gives pt. diarrhea - rids K and Ph -Insulin, dextrose, calcium (short term treatment): dump insulin and pushes K back into cells - BS doesn't like this so give with sugar -Albuterol nebulizer Acidosis -Treat with Sodium bicarbonate (acts as a buffer) May need to adjust dosage of drugs that are excreted via kidney Meds: think what's excreted/filtered in kidneys and adjust done PRN

management - medications for ARF

Dietary considerations - High calorie - Protein restriction: no banana, citrus, tomato - High carbs - Restrict foods high in potassium Older adult: increased risk of rental failure r/t sensitive CR levels, decrease body mass and increase risk of dehydration

management of ARF

Chronic renal failure -End stage renal disease (ESRD) Irreversible Dialysis Risk factors -DM r/t increase sugar in vessels --> damage -HTN: damaged vessel and arterosceloric plaque DM and HTN common together and have increase risk of renal failure with both -Family history -Elderly

Chronic renal failure/end stage renal disease (ESRD) last stage of chronic renal failure is ESRD

Neurologic: effects brain with electrolyte imbalance: confusion, decreased LOC, lethargy, fatigue Cardiovascular: most serious- 90% pts who die of - heart failure, FVE, pulmonary edema, pericarditis ESRD have heart issue GI: diarrhea, N/V, anorexia Dermatologic: uremic acid skin/breath Hematologic: anemia

s/s of chronic renal failure

``` Creatinine: goes up 1st - more sensitive GFR (see pg. 751) Sodium: as you get fluid volume excess it can dilute out - restrict sodium TEGRITY Acidosis: low pH Anemia Calcium/Phosphorus ```

labs for Chronic renal failure

Phosphate binders -PhosLo -Os-Cal Anti-hypertensive meds: diuretic won't hurt kidneys - don't give ACEs Diuretics Epogen-especially with dialysis: hormone used to grow RBC production and vamps up in bone marrow Diet- -low protein fluid restriction-500-800ml + previous day’s 24hr urine output -low K+, Na, Phosphorus -Dietician consult Dialysis

management of chronic renal failure

Education - go home on fluid restriction so educate on consequences/readmission - Fluid restriction - Diet - Daily weight: same time/scale/clothes - Treatments - Complications: watch for edema 1st, low U.O./differences, heart palpitations, muscle cramps/weakness, dizzy, lethargy, hyperkalemia - When to call the MD - Follow up ``` Lab studies -BUN/Cr -GFR -Urinalysis Kidney ultrasound/CT scan: use dye which damages kidneys Urine output Kidney biopsy ```

NM of chronic renal failure

``` Chronic renal failure or acute renal failure Types -Hemodialysis -Peritoneal dialysis -Continuous renal replacement therapy (CRRT) Why dialysis? -Hyperkalemia -Fluid overload -Acidosis -Encephalopathy -Toxins ```

dialysis

Functions as the kidney Blood --> machine --> toxins removed --> blood back to patient 1. Dialyzer-semipermeable membrane (functions as ‘kidney’) 2. Dialysate-solution made of electrolytes; adjustable based on patient need (similar to electrolytes in blood) Anticoagulant used-keeps circuit from clotting - give heparin (check PTT 25-35 seconds) 2 large bore needles used Osmosis-water moves from an area of higher solute concentration to lower solute concentration. *How excess water is removed Diffusion-particles move from an area of higher concentration in the blood to lower concentration *how toxins are removed Ultrafiltration-water moves under high pressure to lower pressure *helps water removal

hemodialysis

Temporary: higher risk of infection - for acute, not chronic -Double lumen -Central line --Internal jugular --Femoral --Subclavian AV fistula- best -Assess for bruie with bell and feel thrill (vibrates) - these tell you how well it's working -atherscleosis, PAD, diabetics with bad vessels are poor canidates AV graft: replace every 3 years

dialysis access

Assessment of fistula or graft - Bruit - Thrill - Observe for s/s of infection (low fever, pain, drainage, red, warm) - Drainage No BP’s on affected arm: can change pressure/ blow vessel No IV sticks on affected arm - tons of backflow and don't want to risk infection/infuse anything else in there

nursing management for dialysis

Continuous vitals during dialysis to check for rebound BP/dehydration Medication adjustment: give the meds it will take them all out - wait until after to take meds --hard with BP meds given before therapy b/c pt. will become hypotensive with dialysis alone Give Education and Support

dialysis management

``` *Hypotension Muscle cramping Dislodging of lines Dysrhythmias r/t K disturbances Air embolism Chest pain r/t electrolyte shift Dialysis disequilibrium r/t electrolyte shift Clotting - main reason fistula fails -Heparin induced thrombocytopenia ```

complications of hemodialysis

In the ICU setting Continuous dialysis very slowly b/c pt is so hemodynamically unstable For hemodynamically unstable patients can adjust meds to compensate

continuous renal replacement therapy (CRRT)

``` Patients who refuse hemodialysis, don't have vessel or want freedom Patient who have no other access Patients who can’t tolerate hemodialysis Tenckhoff catheter Peritoneal membrane-dialyzing membrane Continuous or ’exchanges’ solution of med predetermined by doctor ``` Complication - Peritonitis*: inflamed entire abdominal section and won't be able to do dialysis there anymore - Leakage around site - Bleeding - Incomplete emptying of fluid and need to reposition patient

peritoneal dialysis

Inability of the heart to pump sufficient blood to meet the needs of the tissues for oxygen and nutrients “POOR PUMP"

heart failure

Ejection fraction (EF)- amount of blood ejected with each contraction. Normal 55-65% Systolic heart failure-most common. Alteration in ventricular contraction by weakened heart muscle Diastolic heart failure-stiff heart muscle. Ventricle can’t FILL properly EF is normal in diastolic heart failure EF is reduced in systolic heart failure

heart failure information

Pulmonary congestion Left ventricle can’t pump blood effectively  pulmonary venous blood volume & pressures increase  forces fluid from capillaries into tissues and alveoli  impaired gas exchange S/S: Pulmonary congestion, Dyspnea, Cough, Crackles, Decreased oxygen saturation, Anxiety

left sided heart failure

Many times caused by left sided heart failure Right ventricle pump failure  peripheral congestion Right side of the heart can’t eject blood and can’t handle all the blood that normally returns from venous circulation  backs up into systemic circulation S/S: Hepatomegaly, Ascites, Edema, Weight gain, Anorexia, nausea, JVD Right side cath: Preload pressures, Pulmonary pressures, Determines severity of heart failure

Right sided heart failure

”Volume” Volume in the left ventricle at the end of diastole Excess preload  stress on ventricular wall  increased workload on heart

preload

“Pressure” Pressure required to open the aortic valve Increase in afterload  increased stress on ventricular wall  increased workload on heart

Afterload

Hearts ability to effectively contract Can’t directly measure contractility Sympathetic nervous system response to increase contractility Decreased contractility  increase in preload

contractility

Systolic heart failure results in decreased blood ejected from the ventricle which will stimulate the sympathetic nervous system Heart rate will increase-(sign of worsening heart failure) Cardiac output will decrease Vasoconstriction of the skin, GI tract and kidneys

heart rate

How the heart compensates for the increased workload Increased thickness of the heart muscle Abnormal

ventricular hypertrophy

Diagnostics: Chest X-Ray, 12 lead EKG (Determines arrhythmias, if patient had MI or if theres LV hypertrophy), Echocardiogram (looks for cardiac abnormalities, measures EF), Labs, Right sided heart catheterization Chest x-ray: Determines if the heart is enlarged and/or if there’s pulmonary congestion -Cardiomegaly-systolic dysfunction Labs: CBS, electrolytes, BUN/CR, liver function tests, urinarlysis, BNP

Tests for heart failure

Assessment - Manifestations of fluid overload | Health history - SOB, Orthopnea?, Edema?, ADLs?, Mental status?, Intake and output, Daily weights

Nursing care for heart failure

Ultrafiltration-similar to dialysis except this only pulls off fluid Biventricular pacemaker-leads in right atrium, right ventricle and left ventricular cardiac vein Implantable cardiac defibrillator (ICD)-for patients at high risk of life threatening arrhythmias Ventricular assist device (VAD)- mechanical pump that replaces the function of the left or right ventricle Heart transplant-replaced with a donor heart

heart failure treatments

Gastritis-inflammation of the gastric or stomach mucosa - Acute-several hours to a few days - Hallmark: acute onset - Chronic-repeated exposure to irritating agents or recurring episodes of acute gastritis Causes of acute: -Dietary* -Medications -ETOH – alcohol (irritant in stomach that can damage mucosal lining and pancreatic cells) -Bile reflux – like aspirin -Radiation therapy Concern about skin integrity with ulceration - if it continues it can cause bleeding Mucous membrane-edematous and superficial erosion takes place  secretes a small amount of gastric juice and a lot of mucus superficial ulceration or irritation hemorrhage

Acute gastritis

Symtpoms: -Rapid onset: Body lets you know right away -Abdominal discomfort -Headache -Fatigue -Nausea -Anorexia -Vomiting -Lack of appetite -hiccups Diagnosis -Upper GI series: if serious, drink barium that coats stomach and can see where it’s narrow or inflammed -Endoscopy: upper – long camera placed into stomach and can directly visualize what's going on --This is better because we can directly see it, do biopsy's, sample it, if bleeding and clip it, and can treat while you’re in there -Biopsy

gastritis

Self repair Instruct patient to refrain from ETOH and food until symptoms resolve -Watch for dehydration and correct electrolyte imbalance May need IVF Neutralize acid -Antacids to neutralize acid in stomach If severe you will have a lot of erosion-must stop vomiting due to danger of perforation -If perforation happens, life threatening emergency (hole/bleeding/acid in abdominal cavity) -If vomit so much worry about perforation so stick NG down them and give antiemetics NG tube Analgesics Sedatives Fiber optic endoscopy: flexible tube Surgery if progresses to perforation or something like that: to remove gangrenous or perforated tissue, gastric resection-to treat pyloric obstruction (a narrowing of the pyloric orifice) that can’t be relieved by medical management

management of gastritis

Hiatal hernia-opening in the diaphragm through which the esophagus passes becomes enlarged and part of the upper stomach moves up into the lower portion of the thorax Types: -Sliding-upper stomach and the gastroesophageal junction are displaced upward and slide in and out of the thorax (accounts for 90% of hiatal hernias) --As you eat/swallow/do things it pops up and down --S/S: 50% are asymptomatic, often implicated in reflux -Paraesophageal hernia-all or part of the stomach pushes through the diaphragm beside the esophagus --Out pouch through stomach but other spot is intact --No reflux r/t no backflow of acid – just a piece that’s pouch --Complain of full/tight feeling when they eat r/t pressure it puts (like chest pain) --Mimics acute coronary symptom --S/S: sense of fullness after eating, chest pain, could be asymptomatic, reflux usually doesn't occur, concern with obstruction r/t to cut off blood flow --> ischemia --> death/necrosis --> abscess --hemorrhage, obstruction and strangulation can occur with all types of hernias

hiatal hernia

Sliding -Frequent, small meals to prevent stretching pouch -Do not lay down for 1 hour after eating r/t turning up acid – want to keep food in stomach --Gravity is our friend -Elevate head of bed 4-8 inches (semi fowler to prevent heart burn while laying) -Surgery-with esophageal injury --S/S: 50% are asymptomatic, often implicated in reflux Paraesophageal -Similar to treatment of reflux -Lower acidity, small meals, lower head of bed -Emergency surgery --Correct torsion (twisting) of the stomach --Twist can lead to ischemia which can lead to necrosis S/S: S/S: sense of fullness after eating, chest pain, could be asymptomatic, reflux usually doesn't occur, concern with obstruction r/t to cut off blood flow --> ischemia --> death/necrosis --> abscess --hemorrhage, obstruction and strangulation can occur with all types of hernias Diagnose: Xray, barium swallow, fluoroscopy

Management of hiatal hernia

Gastroesophageal reflux disease (GERD)-back-flow of gastric or duodenal contents into the esophagus (chronic amount of heartburn after you eat) Causes - Some of this is normal! Like in pregnacy - Incompetent lower esophageal sphincter - Pyloric stenosis in lower part - Motility disorder – chronic backflow of acid to esophagus S/S - Burning sensation in esophagus - Dyspepsia (indigestion) - Regurgitation - Dysphagia - Hypersalivation – increase amount of secretions/gastric juices body responds by making more saliva - Esophagitis * *What process do these symptoms mimic? MI OR ACUTE CORONARY SYMPTOMS

gastroesophageal reflux disease (GERD)

Diagnosis: -Endoscopy for definitive answer -**Patient symptoms with course of proton pump inhibitors (PPI) to differentiate GERD from other disease processes --Doesn’t clear up right away r/t decrease amount of acid made in system and must take regularly to lower acid you secrete --GERD-usually responds to PPIs Management: -Teaching! -Low fat diet and no spicy foods -Avoid caffeine, smoking, alcohol, milk, carbonated beverages -Don’t eat or drink 2 hours before bed r/t stimulation of juices to start working and if you lay down it will backflow to esophagus -Maintain normal body weight -Avoid tight fitting clothes -*Elevate head of bed 6-8 inches: sleep on many pillows -Sleep on pillows -Meds = antacids, H2 receptor antagonists (Pepcid, axid, zantac) and PPI (azoles) -Surgery: Nissen fundoplication-wrapping of a portion of the gastric fundus around the sphincter area of the esophagus

GERD

-Inflammation of the biliary system* and carcinoma -Gallbladder inflammation-cholecystitis (inflammation of biliary system) -Gallstones-cholelithiasis (gallstones obstruction biliary system) --Stones plug up and attack -Gallstones-most common disorder of the biliary system --high fatty diets increase risk of this --Stones are insoluble to water so can’t move anywhere -50% of stones made up of cholesterol-insoluble in water Diagnosis -Abdominal US or CT scan

Gallbladder disease | On the right side

Risks: -Obesity r/t diet changes and high cholesterol -Females-especially with multiple pregnancies and increase age -Frequent changes in weight -Estrogen therapy -Gastric bypass -TPN -Cystic fibrosis -Diabetes -Family history S/S: -Silent or mild symptoms that can occur after you eat -Could be symptoms from gallbladder disease or from obstruction of bile -Epigastric distress -Pain -Abscess, necrosis and perforation with continued obstruction* -Biliary colic (gallbladder attack)- Excruciating right abdominal pain; Can come or go – usually on right side; Radiation to back or right; shoulder; Nausea and vomiting; Chills; Belching; Bloating How do nurses know if an abscess occurs? What symptoms will they have? Know abscess if irritation at site, erythema/warmth, tachycardia, fever, pain With heart burn, food relieves it - with this, food worsens it

cholelithiasis

Acute inflammation of the gallbladder -Empyema-gallbladder fills with pus -Anything filled with pus Calculous cholecystitis-gallbladder stone obstructs bile outflow -Gallbladder becomes inflamed and distended Acalculous cholecystitis-gallbladder inflammation without obstruction by gallstones -Occurs after major surgery, trauma (tissue responds with inflammation), burns -Could be caused by imbalance in fluid and electrolyte

Cholecystitis

S/S: -Pain and rigidity of upper right abdomen -Radiates to back or right shoulder or scapula -Nausea and vomiting -Elevated WBC -Positive Murphy’s sign management - Bowel rest – don’t eat r/t that will stimulate bowels -Management of fluid and electrolyte imbalances -Pain management -Antibiotics Surgery-cholecystectomy See page 714, box 25-11 for patient education on lap cholecystectomy -Open gallbladder surgery – split down side and remove it -Laparoscopic cholecystectomy – 3-5 pokes to remove it Nursing management: - Can go home the next day, dress or steri-strips or combo - Tell patient to leave them alone, don’t wash or redress (they will fall off themselves), wait 24-48 hours to shower - Activity: move right away and do IS - Tell patient to call doctor with S/S of infection since it takes a few days to develop (fever, redness, drainage, swollen, tender) or acute pain or severe N/V - NV is #1 complications, so start on ice chips and toast

Cholecystitis

Gastric, duodenal or esophageal ulcer -Dull, nagging pain the worse the ulcer gets Hollowed out area that forms in the mucosal wall of the stomach, in the pylorus, in the duodenum or in the esophagus Stress Ulcer -related mucosal disease (stress ulcers)-acute mucosal ulceration of the duodenal or gastric area that occurs after physiologically stressful events (like mechanically ventilation, MVA) - Clinically different than peptic ulcers - Could be from hypovolemia/hypoperfusion r/t loss of blood to tissue and responds by erosion Concern: bleeding – 2 types of GI bleeds, and perforation - Slow leak: doesn’t fill up stomach, so poop out dark/tarry/coffee ground stool - Big leak: vomit large amounts of blood - OR perforation: ulcer bleeds into cavity and acid floods abdomen

Peptic ulcer disease

Risks -40-60 years old -Infection with gram negative bacteria H. pylori- doesn’t cause ulcers in everyone! -H. pylori can contribute to excessive secretion of HCL in the stomach -Milk, caffeinated beverages, smoking and ETOH increase HCL secretion -NSAIDS -Stress -Spicy foods -Hereditary S/S: -Intermittent usually – not consistent pain -Can be silent -Dull, gnawing pain (Sharp pain means perforation) -Burning sensation in midepigastrium or back -Heart burn -Vomiting-can be from obstruction of pyloric orifice -Bleeding (check to see by stools, H/H) Diagnosis -Physical exam-pain, epigastric tenderness or abdominal distention -Barium study – swallow dye and look where erosions are -*Endoscopy – can look and fix it while in there (can clip, staple, burn or inject with epinephrine to vasoconstrict and clot bleed)

Peptic ulcer diseaes

management - Antibiotics to treat the H. pyloric - Proton Pump Inhibitors (PPI) – reduce acid - Histamine-2 (H2) receptor antagonists - *Encourage patient to continue medications even when symptom free! - Lifestyle changes: Stress reduction, Stop smoking, Dietary - Eat 3 regular meals, No need to eat small, frequent meals as long as antacid or histamine blocker is taken - Surgery - -Necessary for patients with intractable ulcers, life threatening hemorrhage, perforation or obstruction - Vagotomy with or without pyloroplasty-transecting the nerves that stimulate acid secretion and opening the pylorus - -Removing/clipping the vagal nerve since that’s causing the pain - Antrectomy-removal of the pyloric (antrum) portion of the stomach with anastomosis to either the duodenum or jejunum - -Remove bottom part of stomach since that’s where lots of ulcers form

peptic ulcer disease

Complications - Hemorrhage or upper GI bleed-most common complication - -Large hemorrhage-most of the blood is vomited - -Small hemorrhage-much is passed in stool - If a large amount of blood is vomited, what should the nurse worry about? - What does the nurse assess? Interventions? I/O, hypovolemic, kidney function - Perforation (hold in stomach) and penetration (leaking of acid into pancreas or other organs) - Perforation-erosion of the ulcer into the peritoneal cavity - This requires immediate surgery! Why? - Penetration-erosion of the ulcer through the gastric serosa into adjacent structures such as the pancreas, biliary tract or omentum - Symptoms of penetration-back/epigastric pain not relieved with medications - Requires surgical intervention - Postoperatively from surgery = NG tube and drainage/bleeding, Monitor fluid and electrolytes, Assess for s/s of infection/peritonitis - Pyloric obstruction (gastric outlet obstruction)-area distal to pyloric sphincter becomes scarred and stenosed from spasm or edema or from scar tissue - Patients will have nausea, vomiting, constipation, epigastric fullness, anorexia - -If constipated with fever = infection so don’t get them something that will speed up GI tract and look for cause of infection Treatment - NG - Upper GI study/endoscopy - Balloon dilation of pylorus - Antrectomy-if obstruction unrelieved by medical management - Stent placement

Complicaions of peptic ulcer disease

Inflammation/edema of the appendix -Most frequent intraabdominal emergency surgery -Kink or occlusion -Fecalith (harden stool) -Tumor -Foreign body -Adhesions (long fibrous strip in abdomen that pinch off blood flow) Risks -Young (10-30) -Winter months -Family history -Male -Cystic fibrosis Kink or occlusion --> increase in intraluminal pressure --> inflamed appendix fills with pus --> right lower quadrant pain Diagnosis -CBC for WBC to see infection -Imaging = Abdominal xray, Ultrasound, CT scan -Diagnostic laparoscopy: we think it’s this but open up to confirm

Appendicitis

Initial Onset: -Vague epigastric or periumbilical pain -Low grade fever -Nausea and vomiting -Loss of appetite May progress to -Right lower quadrant pain* -McBurney’s Point/Rosvig’s Sign (press on left side and feel pain on right) -Rebound tenderness -Constipation or diarrhea -Pain on urination -Rigidity of the right recuts muscles -Diffuse pain and abdominal distention (with rupture) (rupture can lead to sepsis which can lead to shock) management - Immediate surgery to prevent burst, abscess and death -Can have S/S for a week -Correct/prevent fluid and electrolyte imbalances -Antibiotics -Opioids (#1 treatment for pain like this) -May be discharged with normal temperature and tolerable pain postop Management of gastritis if rupture -Abscess may form and leaks puss then organs have this on them so you need antibiotics and drain -Antibiotics -Drain (watch to see if it’s resolving, getting worse or getting secondary abscess) -NG for bowel rest and to relieve nausea -Risk for peritonitis, intestinal obstruction (treat with NG and then bowel resection), secondary abscesses NG for suspected paralytic ileus prior to surgery

Appendicitis

Inflammation of the peritoneum Also called “hot belly” or “acute abdomen” (distended, swelling, tight, guarding, warm, S/S of infection – fever, tachycardia, more diffused pain) Life threatening emergency r/t entire cavity infected and effects all other organs -May lead to sepsis, organ failure, subsequent infection Serous membrane lining of abdominal cavity and covering the viscera Abdominal organs leak into the abdominal cavity -> bacterial proliferation -> edema of tissues -> exudation (shift) of fluid -> hypermotility of the intestinal tract -> paralytic ileus (piece no longer moving and obstructs) -> accumulation of air/fluid in the bowel (distention) What would cause abdominal organs to leak?? – infection and abscess – one organ has some sort of infection Necrosis from ulcer could perforate stomach, obstruction or trauma or stab wound can lead to issue in peritoneum

Peritonitis

``` Risks -Bacterial infection -Disease of GI tract -Internal reproductive organs -Injury/trauma -Infection of nearby organ outside peritoneum -Abdominal surgeries -Peritoneal dialysis S/S -Diffuse pain ->constant and localized pain near the site of inflammation -Tenderness -Distention -Muscle rigidity -Rebound tenderness -N/V -Fever (100-101) -Increased HR -Elevated white count -May have low H&H r/t hemorrhage with abscess burst -Abnormal electrolytes r/t fluid shift Diagnosis Based on symptoms and labs Abdominal xrays -Free air and fluid -Distended bowel loops CT scan -Abscess formation -Inflammation/infection of organs -Perforation (concern r/t burst and fluid going to peritoneal cavity) Peritoneal aspiration: will help you test specific bacteria and treat it Management Fluid replacement (isotonic) Analgesics Antiemetics NG Monitor breathing to see shock (acidosis will compromise breathing so check stats and EKG) if it progresses and shock gets worse then you ventilate Oxygenation -> ventilation Antibiotics Surgery:Postop complications ICU care often needed Drain- watch output Arterial line I&Os and watch BP to check for damage to kidneys Fluid and electrolyte balance Position for comfort – fetal position Watch for tissue break down, keep patient comfortable, ```

Peritonitis

Inflammation of the pancreas – release of enzyme and pancreas starts eating itself Acute vs chronic Acute -Medical emergency r/t leakage of digestive enzymes into system -Mild will still have damage and will take up to 6 months -High risk for life-threatening complications and mortality Chronic -So much pancreas has been destroyed/calcified that it’s not very functional -May go undetected until large amount of tissue damage -Acute does not necessarily lead to chronic -Characterized by acute attacks Pancreas makes insulin, release glucagon, and makes enzymes that break up fats/enzymes/carbohydrates to get nutrients

Pancreatitis

``` Self-digestion (trypsin) ->vasodilation, inflammation, vascular permeability ->necrosis, erosion -> hemorrhage, organ failure Risks Alcohol Drugs Gallstones will block pancreatic duct and cause issues Trauma Infections close to pancreas Autoimmune disease Duedenitis Peptic ulcer disease Ischemic vascular disease Hyperlipidemia Hypercalcemia Medications Hereditary Idiopathic (15% of cases) Mild: Inflammation and edema localized to pancreas Return to normal function in 6 months At risk for hypovolemic shock, F&E imbalances*, and sepsis Severe: Enzymes from the pancreas damage blood vessels Bleeding/ Thrombosis Necrotic tissue Pancreatic cysts/abscesses Organ failure Shock Renal failure GI bleeding ```

acute pancreatitis

``` S/S: Severe midepigastrium pain Abdominal distention May find palpable mass N/V Grey-Turner sign (result from hemorrhage around flank), Cullen sign (indicates hemorrhage around umbilicus) Mental confusion Agitation Fever Jaundice Hypotension Tachycardia Cyanosis, respiratory distress Col, clammy skin Peritonitis Guarding Diagnosis: Patient history Physical exam Labwork -Serum amylase and lipase will be sky high ** -WBCs -Hypocalcemia: the lower the calcium, the worst the pancreatitis CT scan Management: -Relieve S/S with opiods, IV fluids then TPN, strict NPO, NG to suck out everything NM: Pain relief Breathing – IS and bedrest (problems like pneumonia/atelectasis with no activity so IS is v important) -No moving r/t increase in metabolic rate which kicks in pancreas Nutrition Skin integrity r/t lack of nutrition which slows healing Monitor for complications, especially BS * ```

Acute pancreatitis

Progressive anatomic and functional destruction of the pancreas Fibrous tissue replaces normal tissue after acute attacks – gets hard/calcified Typically due to long term alcohol consumption (toxic effect on pancreatic cells) Less common: -Genetic mutations -Autoimmune -Duct obstruction -Idiopathic S/S: Reoccurring acute attacks Worsening pain, opioid dependence with each Significant weight loss or won’t eat r/t pain Malabsorption (decrease in lipase production) -Steatorrhea: gut stops absorbing nutrients – gray, greasy foul smelling stool Diagnosis: Clinical findings and history Endoscopic retrograde cholangiopancreatography (ERCP) – take long flexable camera down throat to look at pancreas – can use to diagnose and remove stones MRI, CT, ultrasound Lab analysis of steatorrhea Management Zero alcohol PPIs – reduce acid Pain management Pancreaticojejunostomy (Roux-en-Y) Pancreatic stenting if gallstone is main cause Whipple resection (pancreaticoduedenectomy): take a little of everything Endoscopy to look for damage

Chronic pancreatitis

Blockage prevents the normal passage of intestinal contents through the intestinal track (partial or complete) Types: -Adhesions: long fiber strips that can clot off -Intussusception: slips inside of itself and kinks off function -Volvulus: twist of bowel, kinked, no blood flow, ischemic, necrosis -Tumor -Paralytic ileus -Hernias

intestinal obstructions

``` Bulge of tissues through a defect in the abdominal wall or musculature. May result in strangulation of tissues and intestinal obstructions. 1. Ventral (incisional) 2. Inguinal: weak abdominal walls with out pouch from lifting heavy things 3. Umbilical: born with it by belly button S/S: Depends on severity of intestinal obstruction Pain Fever so do not give meds for constipation* Constipation Severe abdominal pain Tenderness in the abdomen Vomiting Distended abdomen Redness or discoloration Risks: Obesity Pregnancy Fluid in the abdominal cavity Abdominal surgery Chronic cough Heavy lifting, such as weight lifting. Repetitive straining during urination or bowel movements. Diagnosis: Physical exam, US or abd xray Management: surgery with mesh or bowel resection You may be asked to cough/stand/sit ```
