APEA 3P HIGH STAKES EXAM | COMPREHENSIVE
PRACTICE EXAMINATION | 200 ORIGINAL QUESTIONS
WITH DETAILED RATIONALES
Exam Overview
The APEA 3P Examination is a 110-minute, 90-question competency-based exam
that tests clinical knowledge in three core domains:
• Physical Assessment (33%)
• Pathophysiology (33%)
• Pharmacotherapeutics (33%)
Core Domains
1. Cardiovascular System
2. Respiratory System
3. Endocrine System
4. Neurological System
5. Gastrointestinal and Renal Systems
6. Musculoskeletal System
7. Dermatological System
8. Reproductive and Women's Health
9. Psychiatric and Behavioral Health
10.Infectious Disease and Pharmacology
SECTION ONE: CARDIOVASCULAR SYSTEM (QUESTIONS 1–25)
,2
Question 1
A 58-year-old male presents with crushing substernal chest pain radiating to the
left arm and jaw, diaphoresis, and nausea. His ECG shows ST-segment elevation in
leads V1–V4. Which coronary artery is most likely occluded?
A. Right coronary artery
B. Left circumflex artery
C. Left anterior descending artery
D. Posterior descending artery
C. Left anterior descending artery
RATIONALE: ST-segment elevation in leads V1–V4 indicates an anterior wall
myocardial infarction, which is typically caused by occlusion of the left anterior
descending (LAD) artery. The LAD supplies the anterior wall of the left ventricle
and the anterior two-thirds of the interventricular septum. This is often referred
to as a "widow-maker" lesion due to the large area of myocardium at risk.
Question 2
A 72-year-old female with a history of hypertension and diabetes presents with
exertional dyspnea, orthopnea, and bilateral lower extremity edema. Her BNP is
850 pg/mL. Which finding on physical examination is most specific for heart
failure?
A. Bibasilar crackles
B. Jugular venous distention
C. S3 gallop
D. Peripheral edema
C. S3 gallop
RATIONALE: An S3 gallop is a low-pitched diastolic sound heard best at the
apex and is highly specific for volume overload and ventricular dysfunction in the
setting of heart failure. While bibasilar crackles, JVD, and peripheral edema are
,3
common findings, they are less specific and can occur in other conditions such as
pneumonia, cirrhosis, or venous insufficiency.
Question 3
A 65-year-old male with atrial fibrillation has a CHA₂DS₂-VASc score of 4. Which
medication is most appropriate for stroke prevention?
A. Aspirin 81 mg daily
B. Warfarin with target INR 2.0–3.0
C. Clopidogrel 75 mg daily
D. No anticoagulation needed
B. Warfarin with target INR 2.0–3.0
RATIONALE: A CHA₂DS₂-VASc score of 2 or greater in males (3 or greater in
females) warrants anticoagulation for stroke prevention in atrial fibrillation.
Warfarin with a target INR of 2.0–3.0 is appropriate. Direct oral anticoagulants
(DOACs) such as apixaban, rivaroxaban, or dabigatran are also options. Aspirin
and clopidogrel are antiplatelet agents, not anticoagulants, and are less effective
for stroke prevention in AF.
Question 4
A 55-year-old male is prescribed lisinopril for hypertension. Which laboratory
value should be monitored most closely?
A. Serum sodium
B. Serum potassium
C. Serum calcium
D. Serum magnesium
B. Serum potassium
RATIONALE: ACE inhibitors such as lisinopril can cause hyperkalemia due to
decreased aldosterone secretion. Potassium levels should be monitored closely,
especially in patients with renal impairment or those taking potassium
, 4
supplements or potassium-sparing diuretics. Renal function should also be
monitored.
Question 5
A 68-year-old female with heart failure is prescribed carvedilol. Which statement
about beta-blocker initiation in HFrEF is correct?
A. Beta-blockers are contraindicated in HFrEF
B. Beta-blockers should be started at low doses and titrated slowly
C. Beta-blockers should be started at maximum doses
D. Beta-blockers are only effective in patients under 70
B. Beta-blockers should be started at low doses and titrated slowly
RATIONALE: Beta-blockers are a cornerstone of HFrEF therapy and reduce
mortality and hospitalization. However, they must be started at low doses and
titrated slowly to avoid decompensation. The negative inotropic effects can
initially worsen heart failure symptoms.
Question 6
A 60-year-old male taking warfarin presents with an INR of 5.5 and no bleeding.
Which action should the NP take?
A. Administer vitamin K
B. Hold warfarin and recheck INR
C. Administer protamine sulfate
D. Increase the warfarin dose
B. Hold warfarin and recheck INR
RATIONALE: An INR of 5.5 without bleeding is supratherapeutic but not
immediately life-threatening. The NP should hold the next dose of warfarin,
recheck the INR, and consider oral vitamin K if the INR remains elevated or if
bleeding occurs. Protamine sulfate is the antidote for heparin, not warfarin.
