SECTION 1: CARDIOVASCULAR ANATOMY & PHYSIOLOGY Q1
– Q8
,2
══════════════════════════════════════
Question 1 of 50
A 62-year-old male presents to the emergency department with crushing
substernal chest pain radiating to his left arm and jaw. His blood
pressure is 168/98 mmHg, heart rate 102 bpm, and he appears
diaphoretic. The attending physician explains that the coronary artery
most commonly responsible for inferior wall myocardial infarction
occludes due to its anatomical position and blood supply territory.
Which coronary artery is the physician describing?
A. Left anterior descending (LAD) artery
B. Left circumflex (LCx) artery
C. Right coronary artery (RCA) ✓ CORRECT
D. Ramus intermedius artery
Correct Answer: C
Rationale: The right coronary artery supplies the inferior wall of the left
ventricle in approximately 85% of individuals (right-dominant
circulation), making it the vessel most commonly occluded in inferior
wall MIs. The LAD typically supplies the anterior wall and anterior
septum, while the circumflex supplies the lateral wall, so neither would
produce classic inferior ST-elevation patterns.
Question 2 of 50
,3
During a cardiac catheterization lab rotation, a cardiovascular
technology student observes that the left ventricular pressure tracing
demonstrates a rapid rise during systole followed by a sharp drop as the
aortic valve opens. The instructor notes that this waveform morphology
reflects the relationship between ventricular pressure and the cardiac
cycle phase known as isovolumetric contraction. What best describes the
hemodynamic events occurring during this phase?
A. Both AV and semilunar valves are open, allowing rapid ejection of
blood into the aorta
B. The mitral valve has closed, the aortic valve remains closed, and
ventricular pressure rises sharply without change in volume ✓
CORRECT
C. The aortic valve opens before the mitral valve fully closes, creating a
brief period of simultaneous filling and ejection
D. Ventricular relaxation begins while the aortic valve is still open,
allowing retrograde flow into the ventricle
Correct Answer: B
Rationale: During isovolumetric contraction, both the atrioventricular
(mitral) and semilunar (aortic) valves are closed, so ventricular volume
remains constant while pressure rises dramatically as the myocardium
contracts against closed valves. Choice A incorrectly describes the rapid
ejection phase when the aortic valve is open, which occurs after
isovolumetric contraction ends once ventricular pressure exceeds aortic
pressure.

Question 3 of 50
A neonate born at 36 weeks gestation is noted to have a continuous
machinery-like murmur best heard at the left upper sternal border. The
pediatric cardiologist explains that this finding reflects a fetal circulatory
structure that failed to close normally after birth. Which structure failed
to undergo normal postnatal closure in this infant?
A. Foramen ovale
B. Ductus arteriosus ✓ CORRECT
C. Ductus venosus
D. Ligamentum arteriosum
Correct Answer: B
Rationale: A patent ductus arteriosus (PDA) produces the characteristic
continuous "machinery" murmur due to continuous shunting of blood
from the high-pressure aorta to the low-pressure pulmonary artery
throughout the cardiac cycle. The foramen ovale (choice A) would cause
a systolic ejection murmur or be asymptomatic, not a continuous
murmur, and the ductus venosus (choice C) connects the umbilical vein
to the inferior vena cava and does not produce an audible murmur.
Question 4 of 50
A 55-year-old female undergoing right heart catheterization for
unexplained dyspnea has the following pressures recorded: RA mean 12
