NURS 6032 Exam 3 2025/2026 Fall Semester
Exam with Correctly Answered Questions Real
Exam (Score A)-Marquette University
Angina pectoris (angina)
"suffocation of the chest"; pain caused by imbalance between oxygen being supplied to
the heart muscle and demand for oxygen by the heart muscle
What can cause a reduction in coronary blood flow that leads to angina?
vasospasm
fixed stenosis
thrombosis
increased HR, contractility, after load, and preload causes an increased oxygen
consumption which can result in?
angina (chest pain)
,main goals for angina therapy
prevent myocardial infarction and death hoping to increase the quantity of life
to reduce symptoms of angina and occurence of ischemia hoping to improve quality of
life
what are the most common drugs used in treating angina pectoris
vasodilators (nitrates)
beta blockers (cardiac depressants)
calcium channel blockers (vasodilator and cardiac depressant)
Loop diuretic (furosemide) how it works
blocks the chloride pump in ascending loop of henle causes copious amounts of high
sodium urine to be excreted (strong diuresis) along with potassium losses
Loop diuretics (furosemide) are typically used in __ sided heart failure.
left sided
,or acute HF with significant fluid overload
Class 1: sodium channel blockers how it works
blocks sodium channels in cell membrane during cardiac conduction
decreases rate of depolarization
___ drug is indicated for life threatening ventricular tachycardias (code drug)
sodium channel blockers (lidocaine)
amiodarone (class 3; K+ channel blocker) how it works
blocks potassium channels during phase 3 which slows repolarization so that a new
action potential cannot form
___ drug is used for ventricular fibrillation or during pulseless ventricular tachycardia.
Can be pro-arrhythmic!!
amiodarone (class 3, potassium channel blocker)
Diltiazem (class 4; calcium channel blocker) how it works
, inhibit movement of calcium during phase 2
acts directly on SA/AV nodes to slow depolarization
___ drug is used for A-fib and severe ventricular tachycardias
diltiazem (class 4; calcium channel blocker)
___ can lead to angina, blood clots, stroke, MI and death
hyperlipidemia
Dietary goals to reduce hyperlipidemia
low fat diet
decrease saturated fats and simple carbohydrates
increase intake of fiber and omega 3 FAs
big 4 lifestyle modification to reduce cholesterol
diet
