APEA 3P Predictor Exam complete
Practice Questions & Detailed Rationales
(Verified Update!!!!! 2026–2027 Edition)
1. A 58-year-old patient presents with crushing substernal chest pain radiating to the left arm
and diaphoresis. Which diagnosis is the priority consideration?
A. Gastroesophageal reflux disease
B. Acute coronary syndrome
C. Costochondritis
D. Panic disorder
Correct Answer: B. Acute coronary syndrome
Rationale: Crushing substernal chest pain with radiation and diaphoresis is highly concerning for
myocardial ischemia. Acute coronary syndrome must be evaluated immediately.
2. Which ECG finding is most consistent with an acute ST-elevation myocardial infarction?
A. ST-segment elevation in anatomically contiguous leads
B. Shortened PR interval
C. Isolated prolonged QT interval
D. Sinus bradycardia
Correct Answer: A. ST-segment elevation in anatomically contiguous leads
Rationale: ST elevation in contiguous leads can indicate acute transmural myocardial injury and
requires emergency evaluation.
3. Which cardiac biomarker is most specific for myocardial injury?
A. Myoglobin
B. CK-MB
C. Troponin
D. LDH
Correct Answer: C. Troponin
,Rationale: Cardiac troponins are highly sensitive and specific markers of myocardial injury and
are central to evaluation of suspected acute coronary syndrome.
4. A patient with stable angina reports chest discomfort consistently occurring with exertion
and resolving with rest. Which medication is commonly used for immediate symptom relief?
A. Sublingual nitroglycerin
B. Warfarin
C. Furosemide
D. Digoxin
Correct Answer: A. Sublingual nitroglycerin
Rationale: Sublingual nitroglycerin rapidly reduces myocardial oxygen demand and relieves
acute anginal symptoms.
5. Which medication should not be combined with nitrates because of the risk of severe
hypotension?
A. Acetaminophen
B. Sildenafil
C. Amoxicillin
D. Metformin
Correct Answer: B. Sildenafil
Rationale: PDE-5 inhibitors such as sildenafil can produce profound hypotension when
combined with nitrates.
6. Which finding is most characteristic of left-sided heart failure?
A. Pulmonary crackles
B. Ascites only
C. Hepatomegaly only
D. Peripheral cyanosis without respiratory symptoms
Correct Answer: A. Pulmonary crackles
Rationale: Left ventricular failure causes pulmonary venous congestion, producing dyspnea,
orthopnea, and crackles.
,7. Which finding is more characteristic of right-sided heart failure?
A. Peripheral edema
B. Pulmonary edema only
C. Hemoptysis
D. Wheezing only
Correct Answer: A. Peripheral edema
Rationale: Right-sided heart failure causes systemic venous congestion, leading to peripheral
edema, jugular venous distention, hepatomegaly, and ascites.
8. Which medication class improves survival in many patients with heart failure with reduced
ejection fraction?
A. ACE inhibitors
B. Antacids
C. Short-acting antihistamines
D. Proton pump inhibitors
Correct Answer: A. ACE inhibitors
Rationale: ACE inhibitors reduce maladaptive neurohormonal activation and have
demonstrated morbidity and mortality benefits in appropriate patients with HFrEF.
9. A patient taking an ACE inhibitor develops persistent dry cough. Which medication class is
an appropriate alternative?
A. ARB
B. Loop diuretic only
C. Anticholinergic
D. Calcium supplement
Correct Answer: A. ARB
Rationale: Angiotensin receptor blockers can provide renin-angiotensin system blockade
without the increased bradykinin-related cough associated with ACE inhibitors.
, 10. Which adverse effect requires monitoring in a patient taking an ACE inhibitor?
A. Hyperkalemia
B. Hypoglycemia
C. Severe hypocalcemia
D. Iron deficiency
Correct Answer: A. Hyperkalemia
Rationale: ACE inhibitors decrease aldosterone activity and can increase serum potassium,
particularly in patients with kidney disease or those taking other potassium-raising medications.
11. A patient has blood pressure readings averaging 168/102 mmHg. This represents:
A. Normal blood pressure
B. Elevated blood pressure
C. Stage 1 hypertension
D. Stage 2 hypertension
Correct Answer: D. Stage 2 hypertension
Rationale: Under current ACC/AHA categories, a systolic pressure ≥140 mmHg or diastolic
pressure ≥90 mmHg falls into stage 2 hypertension.
12. Which lifestyle intervention has a well-established benefit for hypertension?
A. Increased sodium intake
B. Regular aerobic physical activity
C. Heavy alcohol consumption
D. Smoking
Correct Answer: B. Regular aerobic physical activity
Rationale: Regular physical activity can reduce blood pressure and improve cardiovascular risk
factors.
13. Which medication is commonly considered a first-line antihypertensive?
A. Thiazide-type diuretic
B. Opioid analgesic
