APEA Predictor Exam Questions With Correct
Answers (Verified Answers) Plus Rationales
2026 Q&A | Instant Download Pdf
1. A 62-year-old man with hypertension and diabetes presents with
crushing substernal chest pain radiating to his left arm for 30
minutes. What is the priority initial intervention?
A. Administer oral antibiotics
B. Encourage ambulation
C. Obtain a 12-lead ECG immediately
D. Schedule an outpatient stress test
Rationale: A patient with symptoms suggestive of acute coronary
syndrome requires immediate evaluation with a 12-lead ECG within 10
minutes of presentation. Early identification of ST-segment elevation
or other ischemic changes allows rapid initiation of reperfusion
therapy, which significantly reduces morbidity and mortality.
2. Which heart murmur is most characteristic of aortic stenosis?
,A. Holosystolic murmur at the apex
B. Continuous machinery murmur
C. Harsh systolic crescendo-decrescendo murmur at the right upper
sternal border
D. Mid-diastolic rumble
Rationale: Aortic stenosis produces turbulent blood flow across the
narrowed aortic valve, creating a harsh crescendo-decrescendo
systolic murmur best heard at the right second intercostal space with
radiation to the carotid arteries.
3. A patient with atrial fibrillation is at greatest risk for which
complication?
A. Pulmonary fibrosis
B. Embolic stroke
C. Pleural effusion
D. Pneumothorax
Rationale: Blood stagnation within the atria during atrial fibrillation
predisposes to thrombus formation, particularly in the left atrial
appendage. Embolization of these thrombi can lead to ischemic stroke,
making anticoagulation an important treatment consideration.
, 4. Which antihypertensive medication is contraindicated during
pregnancy?
A. Labetalol
B. Methyldopa
C. Nifedipine
D. Lisinopril
Rationale: ACE inhibitors such as lisinopril are teratogenic and may
cause fetal renal dysgenesis, oligohydramnios, skull abnormalities,
and fetal death. Safer alternatives include labetalol, methyldopa, and
nifedipine.
5. Which laboratory test is most useful for monitoring long-term
glycemic control in diabetes?
A. Fasting glucose
B. Random glucose
C. Oral glucose tolerance test
D. Hemoglobin A1C
, Rationale: Hemoglobin A1C reflects average blood glucose over
approximately three months by measuring glycosylated hemoglobin.
It is the standard test for assessing long-term diabetic control.
6. Which symptom is most specific for hyperthyroidism?
A. Weight gain
B. Bradycardia
C. Heat intolerance
D. Dry skin
Rationale: Excess thyroid hormone increases basal metabolic rate,
resulting in heat intolerance, sweating, tachycardia, weight loss,
tremor, and nervousness. Heat intolerance is among the hallmark
clinical findings.
7. A patient presents with sudden unilateral facial drooping involving
the forehead. The most likely diagnosis is:
A. Ischemic stroke
B. Trigeminal neuralgia
C. Bell palsy
D. Myasthenia gravis
