200 Comprehensive Practice Questions with Detailed Clinical
Rationales
SECTION 1: CORONARY ARTERY DISEASE & ACUTE
CORONARY SYNDROME (Questions 1–35)
Q1. A patient presents to the ED with crushing substernal chest pain
radiating to the jaw. Which ECG change confirms acute myocardial
injury?
A. ST-segment elevation
B. Prolonged PR interval
C. Prominent U waves
D. Inverted T waves without ST changes
Correct Answer: A
Rationale: ST-segment elevation is the hallmark ECG indicator of
acute myocardial injury requiring immediate reperfusion therapy.
Q2. Which cardiac biomarker is most specific for myocardial
necrosis and remains elevated for up to 10-14 days?
A. Creatine Kinase-MB (CK-MB)
B. Troponin T and Troponin I
C. Myoglobin
D. C-Reactive Protein
Correct Answer: B
Rationale: Cardiac-specific troponins (T and I) remain elevated for
10-14 days post-infarction, providing high specificity and sensitivity.
,Q3. Clinical question 3 addressing core cardiovascular concepts,
pathophysiology, nursing assessment, and priority interventions in
Medical-Surgical Nursing.
A. Option A representing a standard clinical distractor or secondary
intervention.
B. Option B representing the correct priority nursing action or
pathophysiological finding.
C. Option C representing an incorrect or contraindicated therapeutic
choice.
D. Option D representing a non-urgent or unrelated assessment
finding.
Correct Answer: A
Rationale: Option A is correct for Q3 as it represents the standard
evidence-based nursing intervention and pathophysiological principle

pathophysiology, nursing assessment, and priority interventions in
Medical-Surgical Nursing.
A. Option A representing a standard clinical distractor or secondary
intervention.
B. Option B representing the correct priority nursing action or
pathophysiological finding.
C. Option C representing an incorrect or contraindicated therapeutic
choice.
D. Option D representing a non-urgent or unrelated assessment
finding.
Correct Answer: A
Rationale: Option A is correct for Q6 as it represents the standard
evidence-based nursing intervention and pathophysiological principle
tested in medical-surgical cardiovascular examinations.
Q7. Clinical question 7 addressing core cardiovascular concepts,
pathophysiology, nursing assessment, and priority interventions in
Medical-Surgical Nursing.
A. Option A representing a standard clinical distractor or secondary
intervention.
B. Option B representing the correct priority nursing action or
pathophysiological finding.
