APEA Pathophysiology EXAM WITH COMPLETE 500
QUESTIONS AND CORRECT VERIFIED ANS WERS
LATEST UPDATE JUST RELEASED THIS YEAR
Question: A patient who is in cardiogenic shock will present with:
a high cardiac index
decreased vascular resistance
increased ventricular ejection fraction
mixed venous oxygen saturation - CORRECT ANSWER✔✔mixed venous oxygen saturation
Patients will have a low cardiac index, elevated filling pressures of the left, right, or both
ventricles, and a decreased mixed venous oxygen saturation.
Q:A common cause of diastolic heart failure is:
myocarditis
myocardial infarction
1

dilated cardiomyopathy
hypertension - CORRECT ANSWER✔✔Hypertension
long-term hypertension is a common cause of diastolic heart failure.
Diastolic dysfunction occurs when the filling of one or both ventricles is impaired because the
ventricle has become less compliant.
The heart must pump more forcefully in order to push blood into circulation against increased
vascular resistance.
Question: Which type of angina results from coronary artery vasospasm and occurs in atypical
patterns?
Classic angina
Prinzmetal's angina
Unstable angina
Pleuritic chest pain - CORRECT ANSWER✔✔Prinzmetal's angina
Results from coronary artery vasospasm and occurs in an atypical pattern. It is usually at a single
site. It can occur in a normal or disease vessel. Pain is usually resolved with angina medication.

Classic (stable angina) occurs when the heart is stressed, lasts less than 5 minutes, and usually
resolves with rest.
Unstable angina is considered a medical emergency because it lasts longer than 5 minutes, does
not follow the normal pain pattern, and may not resolve with rest or angina medication. It is
often associated or signals a MI.
Question: With each heart beat, blood within the left and right ventricle is ejected into the:
left atrium only
aorta and pulmonary artery
anterior descending artery
right coronary artery - CORRECT ANSWER✔✔aorta and pulmonary artery
Question: The primary cause of cardiogenic shock in a patient with an acute MI is:
failure of the ventricle to pump blood adequately
failure of the aortic valve to pump blood adequately
regurgitation of the tricuspid valve

regurgitation of the mitral valve - CORRECT ANSWER✔✔failure of the ventricle to pump
adequately
Question: Unstable angina is characterized by:
angina with prolonged activity
angina symptoms lasting >6 months.
increasing crescendo angina
angina with elevated cardiac markers - CORRECT ANSWER✔✔increased crescendo angina
unstable angina is characterized by prolonged angina at rest (usually >20 minutes at rest), and
increasing crescendo angina (now more frequent & longer duration)
Question: Which one of the following produces visible evidence of an underlying problem with
reverse venous flow?
cellulitis
bruising
stasis dermatitis
