, Exam Overview & Content Outline
EXAM PURPOSE
MSN 572 APEA 3P Exam validates competency in the 3 Ps for advanced practice nurses:
Pharmacology, Pathophysiology, and Physical Assessment. Required for NP program progression
and board certification preparation.
CONTENT DISTRIBUTION
• Pharmacology (35%) — Drug classes, mechanisms, prescribing, interactions, monitoring,
controlled substances
• Pathophysiology (35%) — Disease processes, cellular mechanisms, systemic effects, risk factors
• Physical Assessment & Diagnostics (30%) — History, physical exam, lab interpretation, imaging,
differential diagnosis
QUESTION FORMAT & SCORING
Each item presents four options with clinical scenarios. Correct answers are highlighted in green
with checkmark (✓). Every question includes detailed rationale with clinical guidelines. Requires
70% to pass.
STUDY STRATEGY
Master drug classes: antihypertensives, antibiotics, diabetes meds, anticoagulants, psychotropics.
Know pathophysiology: HTN, DM, COPD, HF, CAD. Master physical exam: cardiac, respiratory,
abdominal, neuro. Understand lab values: CBC, CMP, lipids, HbA1c, TSH. Know diagnostic criteria
and guidelines: JNC 8, ADA, GOLD, ACC/AHA.
CURRICULUM ALIGNMENT
Questions reflect current standards: APEA 3P University, AACN Essentials, AANP/ANCC
certification, clinical practice guidelines from AHA, ADA, CDC, USPSTF, and evidence-based
practice.

, SECTION I: Pharmacology
1. First-line antihypertensive for African American patients without CKD:
A. ACE inhibitor
✓ B. Calcium channel blocker or thiazide diuretic
C. Beta blocker
D. ARB only
Rationale: JNC 8 Guidelines: African American patients without CKD: First-line CCB or thiazide diuretic.
ACE inhibitors/ARBs less effective as monotherapy due to low-renin HTN. With CKD: ACE/ARB indicated.
Beta blockers not first-line unless CAD/HF. CCBs: amlodipine, thiazides: HCTZ, chlorthalidone. NP must
consider race and comorbidities.
2. Metformin mechanism of action:
A. Stimulates insulin secretion
✓ B. Decreases hepatic glucose production, increases insulin sensitivity
C. Blocks glucose absorption
D. Increases glucagon
Rationale: Metformin: Biguanide. Mechanisms: 1) Decreases hepatic gluconeogenesis, 2) Increases
peripheral insulin sensitivity, 3) Decreases intestinal glucose absorption. Does NOT stimulate insulin
secretion (no hypoglycemia risk alone). First-line for T2DM per ADA. Contraindicated: eGFR <30, avoid if
<45. Monitor B12, lactic acidosis risk.
3. Black box warning for fluoroquinolones includes:
A. Hypoglycemia only
✓ B. Tendon rupture, peripheral neuropathy, CNS effects, aortic aneurysm
C. Weight gain
D. Hypertension
Rationale: Fluoroquinolones (ciprofloxacin, levofloxacin): Black box warnings: Tendon rupture/tendinitis
(Achilles), peripheral neuropathy (irreversible), CNS effects (seizures, psychosis), aortic
aneurysm/dissection, QT prolongation, C. diff. Avoid in myasthenia gravis. Reserve for serious infections
when alternatives unavailable. NP must counsel and monitor.
4. Warfarin therapeutic INR for atrial fibrillation:
A. 1.0-1.5
✓ B. 2.0-3.0
C. 4.0-5.0
D. 0.5-1.0
Rationale: Warfarin: INR 2.0-3.0 for atrial fibrillation, DVT/PE, most indications. INR 2.5-3.5 for mechanical
heart valves. Monitor: baseline, frequent initially, then q4-6 weeks when stable. Interactions: many drugs,
foods (vitamin K), antibiotics. DOACs (apixaban, rivaroxaban) alternative, no routine monitoring. NP
manages anticoagulation.
5. SSRI first-line for depression with sexual side effects:
