Practice Questions with Detailed Rationales
SECTION 1: CARDIAC PHYSICAL ASSESSMENT AND AUSCULTATION
Question 1
A nurse practitioner is auscultating a patient's chest. When the patient
sits up and leans forward, a high-pitched, blowing murmur is heard at S2.
What does this type of murmur most likely indicate?
A. Mitral stenosis
B. Aortic stenosis
C. Mitral regurgitation
D. Aortic regurgitation
Correct Answer: D. Aortic regurgitation
Rationale: Aortic regurgitation is a soft, high-pitched, blowing
diastolic decrescendo murmur best heard at the 3rd left interspace
at the base when the patient sits up and leans forward. Mitral
stenosis is a low-pitched diastolic rumble best heard at the apex in
the left lateral position. Aortic stenosis is a loud, harsh murmur
midsystole radiating to the neck. Mitral regurgitation is a loud
blowing murmur heard at the apex and is pansystolic.
Question 2
Which of the following is NOT part of Virchow's Triad?
A. Hypercoagulability
,B. Damage to endothelial cells
C. Sympathetic tone
D. Turbulent blood flow
Correct Answer: C. Sympathetic tone
Rationale: Virchow's triad describes the three main factors that lead
to thrombosis: hypercoagulability, endothelial damage, and turbulent
blood flow (circulatory stasis). Sympathetic tone is not a component
of Virchow's triad and does not directly affect blood clotting.
Question 3
Regarding the split S2 heart sound, which of these is false?
A. It is a normal phenomenon
B. The aortic valve closes significantly earlier than the pulmonic valve
C. It is noted only in the aortic auscultatory area
D. It occurs on end inspiration
Correct Answer: C. It is noted only in the aortic auscultatory area
Rationale: A split S2 is a normal phenomenon that can be heard
throughout the precordium, not just in the aortic area. During
inspiration, increased venous return to the right ventricle delays
pulmonic valve closure, causing the split.
Question 4
Upon percussion of the chest, you notice hyperresonance. Which of the
following choices would most likely be the cause?
A. Atelectasis
B. Normal lung
,C. Pneumothorax
D. Pulmonary embolism
Correct Answer: C. Pneumothorax
Rationale: Hyperresonance on chest percussion is a classic finding
in pneumothorax due to air trapped in the pleural space. Atelectasis
produces dullness, normal lung produces resonance, and pulmonary
embolism typically does not alter percussion notes.
Question 5
Which of the following is not a common finding of acute left-sided heart
failure?
A. Coarse rales in all lung fields
B. Hepatomegaly
C. Wheezing, frothy cough
D. An S3 gallop sound
Correct Answer: B. Hepatomegaly
Rationale: Hepatomegaly is common in chronic right-sided heart
failure but is much less common in acute heart failure. Coarse rales
over all lung fields; a wheezing, frothy cough; and an S3 gallop are
all common findings of acute, left-sided heart failure.
Question 6
With regard to S3 and S4 heart sounds, which statement is true?
A. An S3 sounds like "Kentucky" and is expected during pregnancy but
otherwise, it is not a normal finding in the adult.
B. An S3 is an atrial gallop and sounds like "Tennessee."
, C. An S4 sounds like "Kentucky" and is expected during pregnancy but
otherwise, it is not a normal finding in the adult.
D. An S4 is a ventricular gallop and sounds like "Tennessee."
Correct Answer: A. An S3 sounds like "Kentucky" and is expected
during pregnancy but otherwise, it is not a normal finding in the
adult.
Rationale: An S3 heart sound is a ventricular gallop that matches the
cadence of the word "Kentucky" and typically presents as a result of
increased fluid states; although it may be normal during pregnancy,
presentation of the S3 heart sound at other times may indicate
conditions such as chronic heart failure. An S4 heart sound, on the
other hand, is an atrial gallop that matches the cadence of
"Tennessee" and is often associated with conditions that result in a
stiff ventricular wall, such as myocardial infarction and chronic
hypertension.
Question 7
Which of the following statements is not typical of the heart murmur with
which it is associated?
A. A grade I/VI murmur is barely audible.
B. A grade II/VI murmur is associated with a thrill.
C. A grade III/VI murmur is moderately loud.
D. A grade IV/VI murmur is loud with a palpable thrill.
Correct Answer: B. A grade II/VI murmur is associated with a thrill.
Rationale: A grade II/VI murmur is soft but readily heard. A thrill is
