certification standards and US university graduate-level nursing education requirements. standards and reflects
the question style commonly seen on accredited program examinations. Students consistently achieving above the

Section 1: Cardiovascular (Questions 1-23)
1 In a patient with acute decompensated heart failure and a pulmonary artery
catheter in place, which hemodynamic profile is most consistent with
cardiogenic shock and would warrant immediate inotropic support?
A) Cardiac index 2.1 L/min/m², PCWP 18 mm Hg, SVR 1200 dynes-s-cm
B) Cardiac index 1.8 L/min/m², PCWP 28 mm Hg, SVR 1400 dynes-s-cm
C) Cardiac index 2.5 L/min/m², PCWP 14 mm Hg, SVR 800 dynes-s-cm
D) Cardiac index 3.0 L/min/m², PCWP 10 mm Hg, SVR 700 dynes-s-cm
Answer: B
Rationale: Cardiogenic shock is characterized by low cardiac index (<2.2
L/min/m²), elevated PCWP (>18 mm Hg), and high SVR due to compensatory
vasoconstriction. Option B shows the lowest CI and highest PCWP with
elevated SVR. Option A has borderline CI but lower PCWP. Options C and D
show high output states inconsistent with shock.
2 A patient with a wide-complex tachycardia (QRS 140 ms, rate 180/min) is
hemodynamically unstable. After synchronized cardioversion fails, which
intervention is most appropriate next?
A) Administer amiodarone 300 mg IV push
B) Perform unsynchronized defibrillation at 200 J
,C) Administer adenosine 6 mg rapid IV push
D) Attempt overdrive pacing via transvenous pacemaker
Answer: B
Rationale: When synchronized cardioversion fails for unstable tachycardia, the
rhythm may be ventricular fibrillation or polymorphic VT; unsynchronized
defibrillation is indicated. Amiodarone is appropriate after defibrillation or for
stable rhythms. Adenosine is for stable supraventricular tachycardia. Pacing is
not first-line for unstable VT.
3 Which of the following best explains the mechanism by which angiotensin II
contributes to adverse left ventricular remodeling in chronic heart failure?
A) Increased afterload via vasodilation and decreased contractility
B) Stimulation of fibroblast proliferation and collagen deposition
C) Enhanced nitric oxide production leading to myocardial stunning
D) Inhibition of aldosterone secretion reducing sodium excretion
Answer: B
Rationale: Angiotensin II promotes myocardial fibrosis by stimulating
fibroblast activity and collagen synthesis, leading to stiffening and
hypertrophy. It also increases afterload via vasoconstriction, not vasodilation
(A). It decreases nitric oxide (C) and stimulates aldosterone (D).
4 A patient with an anterior ST-elevation myocardial infarction (STEMI)
develops a new holosystolic murmur at the apex 48 hours after presentation.
Which complication is most likely?
A) Papillary muscle rupture
B) Ventricular septal rupture
C) Free wall rupture
D) Pericarditis
Answer: A
Rationale: A new apical holosystolic murmur after anterior STEMI is classic for
papillary muscle rupture causing acute mitral regurgitation. Ventricular septal
rupture produces a harsh holosystolic murmur at the left lower sternal border.
Free wall rupture causes electromechanical dissociation. Pericarditis produces a
friction rub.
,5 In a patient with atrial fibrillation and a CHADS-VASc score of 3, which
factor most strongly influences the decision to use a direct oral anticoagulant
(DOAC) over warfarin?
A) Presence of a mechanical heart valve
B) Creatinine clearance of 25 mL/min
C) History of gastrointestinal bleeding
D) Concomitant use of amiodarone
Answer: A
Rationale: DOACs are contraindicated in patients with mechanical heart valves
due to increased risk of thromboembolism. Warfarin is the only approved
anticoagulant in that setting. Severe renal impairment (CrCl <30) favors
warfarin but is not an absolute contraindication for all DOACs. GI bleeding
and amiodarone interactions affect choice but are not the strongest factor.
6 A patient with hypertrophic cardiomyopathy (HCM) experiences worsening
dyspnea and presyncope with exercise. Which physiologic change most
directly explains these symptoms?
A) Increased left ventricular end-diastolic volume
B) Decreased left ventricular outflow tract gradient
C) Increased myocardial oxygen demand and decreased diastolic filling
D) Enhanced coronary perfusion pressure
Answer: C
Rationale: In HCM, hypertrophy and diastolic dysfunction impair filling, and
dynamic LVOT obstruction worsens with tachycardia and increased
contractility during exercise, increasing oxygen demand and reducing cardiac
output. LVEDV often decreases, not increases (A). Gradient increases with
exercise (B). Coronary perfusion may be impaired (D).
7 Which finding on a 12-lead ECG is most specific for acute pericarditis?
A) PR segment depression in limb leads and PR elevation in aVR
B) Pathologic Q waves in leads II, III, and aVF
C) ST elevation >5 mm in leads V1-V3
D) T wave inversion in leads V5 and V6
Answer: A
Rationale: PR segment changes (depression in limb leads, elevation in aVR) are
highly specific for acute pericarditis due to atrial involvement. ST elevation is
, diffuse but not as specific; >5 mm ST elevation suggests STEMI. Q waves
indicate infarction. T inversion is nonspecific.
8 A patient in the ICU has a continuous arterial pressure waveform. The
waveform shows a delayed upstroke, low amplitude, and a dicrotic notch that
is barely visible. Which condition is most consistent with these findings?
A) Severe aortic stenosis
B) Aortic regurgitation
C) Hyperdynamic state
D) Hypovolemia
Answer: A
Rationale: Severe aortic stenosis causes a delayed carotid upstroke (pulsus
parvus et tardus) and low pulse pressure with a diminished dicrotic notch.
Aortic regurgitation shows a wide pulse pressure and rapid upstroke.
Hyperdynamic states have brisk upstrokes. Hypovolemia shows a low
amplitude but normal upstroke.
9 A patient with non-ST-elevation myocardial infarction (NSTEMI) undergoes
coronary angiography revealing a 70% stenosis in the left anterior
descending artery. Which factor would most strongly justify
revascularization over medical management?
A) Elevated high-sensitivity troponin I level
B) Presence of multivessel disease
C) Fractional flow reserve (FFR) of 0.72
D) Left ventricular ejection fraction of 50%
Answer: C
Rationale: FFR "d0.80 indicates ischemia-causing stenosis, and revascularization
improves outcomes. Elevated troponin confirms infarction but not necessarily
ischemia. Multivessel disease may be managed medically. EF 50% is normal
and does not mandate revascularization.
10 Which of the following is the most appropriate initial antiarrhythmic for a
patient with stable, symptomatic atrial fibrillation and a history of coronary
artery disease with prior myocardial infarction?
A) Flecainide
B) Propafenone
