2026/2027 Edition | 200 Multiple-Choice Questions | 7 Sections | Aligned with AACN PCCN Examination Blueprint
Directions: Each question has four options (A–D). The correct option is marked [CORRECT] in accent color. A
detailed rationale follows each question, providing advanced progressive care clinical reasoning with evidence-based
practice standards (Surviving Sepsis Campaign 2021, ARDSNet, AHA/ASA Stroke Guidelines, Brain Trauma
Foundation, AACN Synergy Model). Content domains span Clinical Judgment, Professional Caring, and Clinical
Inquiry per the AACN PCCN examination blueprint. Each verified answer includes pathophysiology, pharmacology
mechanisms, and hemodynamic principles supporting the correct choice and distinguishing common PCCN exam
pitfalls.
Section 1: Cardiovascular System
ACS, Heart Failure, Dysrhythmias, Valvular Disease, Cardiomyopathies, and Vascular Disorders (Q1-Q45)
Q1: A 58-year-old male presents with substernal chest pressure radiating to the left arm, diaphoresis,
and nausea. The 12-lead ECG shows ST-segment elevation in leads II, III, and aVF with reciprocal
depression in I and aVL. Which artery is MOST likely occluded?
A. Left anterior descending (LAD)
B. Right coronary artery (RCA) [CORRECT]
C. Left circumflex (LCx)
D. Left main coronary artery
Correct Answer: B
Rationale: ST elevation in II, III, and aVF indicates an inferior wall STEMI, most commonly caused by occlusion
of the right coronary artery (RCA). Reciprocal depression in I and aVL supports inferior localization. LAD
occlusion causes anterior STEMI (V1-V4); LCx causes lateral STEMI (I, aVL, V5-V6); left main causes
widespread ST depression or elevation in aVR. PCCN-aligned: inferior STEMI can cause RV infarction (obtain
right-sided leads V4R), bradycardia, and respond poorly to nitrates due to preload dependence.

Q2: A patient receiving IV nitroglycerin for chest pain develops hypotension (BP 84/50) and a
paradoxical drop in BP with inspiration. Which finding would BEST confirm the suspected
complication?
A. Jugular venous distention (JVD) with muffled heart sounds and hypotension (Beck's triad)
[CORRECT]
B. Diffuse ST depression in anterior leads
C. Widened mediastinum on chest X-ray
D. S3 gallop on auscultation
Correct Answer: A
Rationale: Beck's triad (JVD, muffled heart sounds, hypotension) indicates cardiac tamponade, a rare but
life-threatening complication of RV infarction and acute cardiac rupture. The paradoxical pulse (drop in systolic
BP >10 mmHg with inspiration) is also classic. PCCN-aligned: in inferior/RV STEMI, nitroglycerin reduces
preload, which can precipitate cardiovascular collapse; always give IV fluids first if RV infarct is suspected. ST
depression suggests ischemia; widened mediastinum suggests aortic dissection; S3 indicates heart failure.
Q3: A patient presents 2 hours after onset of chest pain. ECG shows ST elevation in V2-V4. The
patient is going for primary PCI. According to AHA/ACC guidelines, the door-to-balloon time goal is:
A. 30 minutes
B. 60 minutes
C. 90 minutes [CORRECT]
D. 180 minutes
Correct Answer: C
Rationale: The AHA/ACC guideline recommends a door-to-balloon time of ≤90 minutes for primary PCI in
STEMI patients. This timeframe is critical for myocardial salvage. PCCN-aligned: door-to-needle time for
fibrinolytics is ≤30 minutes when PCI is not available within 120 minutes of first medical contact. The 90-minute
D2B goal is a Core Measure and a PCCN exam staple. Delays increase mortality.
Q4: A 72-year-old female with NSTEMI is started on dual antiplatelet therapy (DAPT) of aspirin plus
ticagrelor. Which finding requires the MOST urgent intervention?
A. Heart rate of 95 bpm
B. BP of 110/68 mmHg
C. Progressive dyspnea with new ST depression in V4-V6 [CORRECT]
D. Mild bruising at IV site
Correct Answer: C
Rationale: Progressive dyspnea with new ST depression in V4-V6 suggests ongoing ischemia/instability in a
NSTEMI patient, indicating failure of medical management and the need for urgent invasive strategy (coronary
angiography). DAPT bleeding manifests as bruising or GI bleeding; mild bruising alone is expected and not
life-threatening. PCCN-aligned: ongoing ischemia, hemodynamic instability, or sustained VT in NSTEMI
warrants immediate invasive strategy within 2 hours.

Q5: A patient post-PCI develops sudden onset of chest pain, hypotension, and diffuse ST elevation in
multiple coronary territories. The MOST likely complication is:
A. Stent thrombosis [CORRECT]
B. Contrast-induced nephropathy
C. Puncture site hematoma
D. Vasovagal reaction
Correct Answer: A
Rationale: Sudden chest pain with hypotension and diffuse ST elevation post-PCI is most consistent with acute
stent thrombosis — a catastrophic complication requiring immediate return to the cath lab. Stent thrombosis is
more common in the first 24 hours (acute) and is associated with high mortality. PCCN-aligned: ensure DAPT is
continued without interruption, platelet function testing if suspected non-response, and immediate physician
notification. Contrast nephropathy causes rising creatinine; puncture hematoma causes local swelling;
vasovagal causes transient hypotension without ST changes.
Q6: A patient with acute decompensated heart failure (HFrEF, EF 25%) presents with pulmonary
edema, BP 88/55, and cool extremities. Which vasoactive medication is MOST appropriate?
A. Milrinone
B. Norepinephrine
C. Nitroprusside
D. Dobutamine [CORRECT]
Correct Answer: D
Rationale: Dobutamine, a beta-1 agonist, increases contractility (inotrope) and is appropriate for low-output
HF with hypotension. Milrinone (PDE-III inhibitor) also increases contractility but causes more vasodilation,
potentially worsening hypotension. Norepinephrine is preferred in cardiogenic shock with severe hypotension,
but in low-output HF with mild hypotension, dobutamine is first-line inotrope. Nitroprusside is contraindicated
in hypotension. PCCN-aligned: dobutamine may increase HR and myocardial oxygen demand; monitor for
tachyarrhythmias and ischemia.
Q7: A patient with HFrEF is on a maintenance beta-blocker (carvedilol) and presents with acute
decompensation. Which intervention is MOST appropriate regarding the beta-blocker?
A. Continue full dose
B. Reduce dose by 50% or hold temporarily [CORRECT]
C. Discontinue permanently
D. Double the dose
Correct Answer: B
Rationale: In acute decompensated HFrEF, beta-blockers should be reduced or held temporarily until the
patient is euvolemic and stable, then reinitiated at a lower dose and titrated. PCCN-aligned: abruptly stopping
beta-blockers can cause rebound tachycardia and ischemia; chronic beta-blocker therapy improves long-term
mortality in HFrEF. Continuing full dose may worsen acute decompensation; doubling is contraindicated;
permanent discontinuation eliminates mortality benefit.

Q8: A heart failure patient has a BNP of 1,800 pg/mL. Which finding is the MOST specific indicator
of poor prognosis?
A. BNP alone
B. BNP with hyponatremia (Na 128) and elevated troponin [CORRECT]
C. Heart rate of 90 bpm
D. Mild peripheral edema
Correct Answer: B
Rationale: Hyponatremia (Na <130) and elevated troponin in the setting of elevated BNP are independent
predictors of poor prognosis and increased mortality in acute decompensated heart failure. The combination
indicates severe neurohormonal activation and possible myocyte injury. PCCN-aligned: BNP >1,000 correlates
with worse outcomes; hyponatremia reflects AVP activation; troponin elevation without MI indicates
subendocardial injury from wall stress. HR 90 and edema are not prognostic markers.
Q9: A 65-year-old with chronic AFib is on warfarin (INR 2.5) and metoprolol. The patient presents
with acute ischemic stroke last seen well 1.5 hours ago. CT head is negative for hemorrhage. Which
intervention is MOST appropriate?
A. IV alteplase (tPA) — it is contraindicated due to INR >1.7 [CORRECT]
B. IV alteplase (tPA) — INR is within safe range
C. Immediate anticoagulation with heparin
D. Aspirin 325 mg orally
Correct Answer: A
Rationale: IV alteplase is CONTRAINDICATED when INR >1.7 (or PT >15s), as this significantly increases
hemorrhagic transformation risk. The patient's INR of 2.5 exceeds this threshold, ruling out systemic alteplase.
PCCN-aligned: AHA/ASA stroke guidelines list oral anticoagulant use with INR >1.7 as a strict exclusion
criterion. The patient should be considered for mechanical thrombectomy if LVO is present and other criteria
met.
Q10: A patient is in monomorphic VT with a pulse but is hemodynamically stable (BP 110/70,
asymptomatic). Which intervention is FIRST-line per ACLS?
A. Immediate synchronized cardioversion
B. IV amiodarone 150 mg over 10 minutes [CORRECT]
C. IV adenosine 6 mg
D. Defibrillation at 200 J
Correct Answer: B
Rationale: Stable monomorphic VT with a pulse is treated FIRST with antiarrhythmic medications (amiodarone
150 mg IV over 10 minutes is first-line per ACLS; procainamide or sotalol are alternatives). Synchronized
cardioversion is reserved for unstable VT or if medications fail. Adenosine is used for SVT, not VT; defibrillation
is for pulseless VT/VF. PCCN-aligned: assess for instability (hypotension, chest pain, altered mental status,
acute heart failure) — if any present, cardiovert immediately.
