Topic 1: Cardiovascular Assessment and Diagnostic
Interpretation
Questions 1–20
1. Which heart sound is most commonly associated with left ventricular failure and heard
best at the apex during auscultation?
A. S1
B. S2
C. S3
D. S4
Correct Answer: C. S3
Rationale: The S3 heart sound, often called a "ventricular gallop," is typically associated
with heart failure and indicates increased fluid volume and decreased ventricular
compliance, especially in the left ventricle.
2. A patient presents with chest pain. Which lab test is the most specific and reliable
indicator of myocardial infarction?
A. Creatine kinase (CK)
B. Myoglobin
C. Troponin I
D. Lactate dehydrogenase (LDH)
Correct Answer: C. Troponin I
Rationale: Troponin I is highly specific to cardiac muscle injury and remains elevated for up
to 7–10 days post-infarction, making it the most reliable biomarker for MI.

3. During a cardiovascular assessment, a nurse notes a displaced point of maximal
impulse (PMI). What condition is this most indicative of?
A. Pulmonary hypertension
B. Pericarditis
C. Left ventricular hypertrophy
D. Atrial fibrillation
Correct Answer: C. Left ventricular hypertrophy
Rationale: A displaced PMI to the left and downward suggests an enlarged left ventricle,
typically caused by conditions such as hypertension or cardiomyopathy.
4. Which ECG change is most indicative of myocardial ischemia?
A. ST segment depression
B. Peaked T waves
C. PR interval shortening
D. QRS complex widening
Correct Answer: A. ST segment depression
Rationale: ST depression suggests subendocardial ischemia and is commonly seen in
unstable angina or non-ST elevation MI.
5. A patient is diagnosed with pericardial effusion. What physical exam finding would most
concern the nurse?
A. Bradycardia
B. Bounding pulses
C. Muffled heart sounds
D. Loud S1
, 4
Correct Answer: C. Muffled heart sounds
Rationale: Muffled heart sounds are a hallmark sign of pericardial effusion and may
indicate impending cardiac tamponade, which is life-threatening.
6. Which non-invasive test provides the most detailed information about heart chamber
size, function, and ejection fraction?
A. Chest X-ray
B. ECG
C. Echocardiogram
D. Cardiac enzymes
Correct Answer: C. Echocardiogram
Rationale: An echocardiogram provides real-time imaging of heart structures, allowing for
evaluation of size, motion, and ejection fraction.
7. When assessing a patient for jugular venous distention (JVD), the nurse should position
the patient at what angle?
A. 15 degrees
B. 30 degrees
C. 45 degrees
D. 90 degrees
Correct Answer: C. 45 degrees
Rationale: JVD is best visualized with the head of the bed elevated to 45 degrees, which
allows the jugular veins to distend if venous pressure is elevated.
