NR601 WEEK 3 QUIZ: PRIMARY CARE OF
THE MATURING & AGED FAMILY
PRACTICUM, (LATEST 2026/2027 UPDATE),
WITH CORRECT/ACCURATE ANSWERS
AT CHAMBERLAIN COLLEGE OF NURSING
Q1. Which finding on cardiac catheterization is MOST consistent
with mitral regurgitation?
A. Fixed coronary obstruction and ST-segment elevation
B. Decreased right atrial pressure and tricuspid regurgitation
C. Elevated pulmonary capillary wedge pressure with low cardiac output
D. Elevated left atrial pressure and abnormal regurgitant flow
Answer: D
Rationale: Mitral regurgitation allows blood to flow back from the left ventricle into
the left atrium during systole. Cardiac catheterization shows elevated left atrial
pressure and evidence of regurgitant flow. This distinguishes it from conditions
affecting coronary arteries or right-sided heart structures.
Q2. A 72-year-old male with hypertension and type 2 diabetes
presents with paroxysmal atrial fibrillation. What is the MOST
appropriate initial step in determining thromboembolic risk?
A. Calculate the CHA₂DS₂-VASc score to guide anticoagulation decisions
B. Begin rate control with a beta-blocker regardless of symptoms
C. Perform electrical cardioversion to restore sinus rhythm
D. Initiate anticoagulation therapy immediately due to age
Answer: A
Rationale: The CHA₂DS₂-VASc score estimates stroke risk in patients with atrial
fibrillation and guides anticoagulation therapy. Immediate anticoagulation or rhythm
interventions are considered after risk stratification.
, Q3. Which ECG finding is MOST associated with aortic stenosis?
A. Delta waves and short PR interval
B. ST-segment elevation in inferior leads
C. Prominent R waves in V5/V6 and deep S waves in V1/V2
D. Tall, peaked T waves in precordial leads
Answer: C
Rationale: Aortic stenosis causes left ventricular hypertrophy due to chronic pressure
overload. This is reflected on ECG as prominent R waves in lateral leads (V5/V6) and
deep S waves in septal leads (V1/V2).
Q4. Which physical exam finding is MOST characteristic of aortic
regurgitation?
A. High-pitched, blowing diastolic murmur at the left sternal border
B. Opening snap with low-pitched diastolic rumble at the apex
C. Holosystolic murmur at the apex radiating to the axilla
D. Crescendo-decrescendo systolic murmur radiating to the carotids
Answer: A
Rationale: Aortic regurgitation produces a high-pitched, blowing diastolic murmur
best heard along the left sternal border. This occurs as blood flows back from the
aorta into the left ventricle during diastole.
Q5. Which echocardiographic finding is MOST consistent with aortic
stenosis?
A. Restricted aortic valve opening with elevated pressure gradient
B. Dilated left ventricle with decreased ejection fraction and thin walls
C. Reduced mitral valve motion and left atrial enlargement
D. Enlarged right ventricle and tricuspid regurgitation
Answer: A
Rationale: Echocardiography in aortic stenosis typically shows limited valve opening
with increased transvalvular pressure gradients. These findings confirm the
obstruction and allow assessment of severity.
Q6. Which physical exam finding is MOST characteristic of mitral
regurgitation?
