Total Questions: 85
Format: Multiple choice, case-based
Target: Nurse Practitioner students
Focus: Advanced clinical reasoning, differential diagnosis, evidence-based
management, Next Gen NCLEX/APCK style
Section 1: Cardiovascular – Chest Pain & Dyspnea (Questions 1–12)
Case 1
A 58-year-old male with hypertension, DM type 2, and smoking history presents
with substernal chest pressure radiating to the jaw, associated with diaphoresis and
nausea. Symptoms began 45 minutes ago while shoveling snow. BP 160/90, HR
110, SpO2 94% on RA. ECG shows ST elevation in leads V2–V4.
1. What is the most appropriate next step?
A. Oral aspirin 324 mg and sublingual nitroglycerin, then admit for medical
management
B. Emergent PCI within 90 minutes of arrival
C. CT coronary angiography
D. Serial troponins every 4 hours x3
Correct Answer: B
Rationale: STEMI requires immediate reperfusion. PCI within 90 minutes is gold
, standard (door-to-balloon time). Thrombolytics if PCI not available within 120
minutes.
2. Which finding is most specific for STEMI equivalent?
A. ST depression in leads V1–V3
B. ST elevation in aVR only
C. New LBBB with concordant ST elevation
D. T wave inversion in lateral leads
Correct Answer: C
Rationale: New LBBB with ST elevation >1mm concordant with QRS is STEMI
equivalent (Sgarbossa criteria). Requires emergent cath.
3. The patient develops hypotension after NTG. Next best action?
A. Increase IV fluids to 2L bolus
B. Start dopamine drip
C. Hold NTG, assess RV infarct with right-sided ECG
D. Administer atropine
Correct Answer: C
Rationale: Inferior STEMI may involve right ventricle; NTG reduces preload →
hypotension. Right-sided ECG needed to confirm RV infarct; fluids first line if RV
involved.
Section 2: Respiratory – Shortness of Breath (13–25)
Case 2
A 72-year-old female with COPD (GOLD 3) presents with increased dyspnea,
purulent sputum, and fever for 3 days. On exam: tachypnea, accessory muscle use,
barrel chest, SpO2 88% on 2L NC. Alert but tired.
4. Which arterial blood gas (ABG) finding is most consistent with acute
exacerbation of COPD?
A. pH 7.35, PaCO2 55, PaO2 65, HCO3 28
B. pH 7.40, PaCO2 40, PaO2 90, HCO3 24
C. pH 7.30, PaCO2 65, PaO2 55, HCO3 30
D. pH 7.48, PaCO2 30, PaO2 70, HCO3 22
