NUR 402 Cardiomyopathy Exam Questions And
Correct Answers
Cardiomyopathy - ANSWER Group of diseases that affect myocardial structure or
function
Usually leads to HF
What does this do to the body with cardiomyopathy? - ANSWER Impaired CO:
This leads to increased vascular resistance and sodium/fluid retention, putting
increased workload on the heart (which is what eventually leads to HF)
What is the major electrolyte imbalance with cardiomyopathy? - ANSWER
Hypernatremia
Types of cardiomyopathy - ANSWER Dilated
Hypertrophic
Restrictive
Pathophys in dilated cardiomyopathy - ANSWER Increased chamber size & volume but
no thickening of ventricle walls
Ventricles have elevated systolic and diastolic volumes but decreased EF
What meds are given to decrease preload in dilated cardiomyopathy? - ANSWER
Nitrates
Diuretics
, Decrease blood going to heart
What meds are given to decrease afterload in dilated cardiomyopathy? - ANSWER ACE
inhibitors
Side effects of ACE inhibitors - ANSWER Dry cough
Hyperkalemia
What meds given to control neurohormonal stimulation in dilated cardiomyopathy? -
ANSWER Beta blockers
Aldosterone antagonist- spirinolactone
How would you treat the patient with dilated cardiomyopathy that develops a-fib? -
ANSWER Antidysrhythmics
Anticoagulants
What may a pt with dilated cardiomyopathy require? - ANSWER 1) Ventricular assist
device
2) Heart transplant
Pathophys in hypertrophic cardiomyopathy - ANSWER Thickened left ventricular wall
causes decreased chamber and size
Causes ventricles to take a longer time to relax after systole
Major manifestation of hypertrophic cardiomyopathy - ANSWER Exertional dyspnea
How do you improve ventricular filling in hypertrophic cardiomyopathy? - ANSWER 1)
Decreasing contractility
