SECTION 1: Cardiovascular System (15 Questions)
Q1: A patient with an arterial line has a systolic blood pressure of 88 mmHg, mean arterial
pressure (MAP) of 65 mmHg, and heart rate of 110 bpm. The CVP reading is 4 mmHg. Which
hemodynamic profile is most consistent with these findings?
A. Cardiogenic shock
B. Hypovolemic shock [CORRECT]
C. Septic shock with high cardiac output
D. Neurogenic shock
Correct Answer: B
Rationale: The combination of low systolic BP, low-normal MAP, tachycardia, and low CVP (4
mmHg indicates reduced preload) is classic for hypovolemic shock. CVP <5 mmHg suggests
inadequate venous return/volume. Cardiogenic shock (Option A) would show elevated CVP.
Septic shock (Option C) typically has low/normal CVP with high cardiac output initially.
Neurogenic shock (Option D) presents with bradycardia and low systemic vascular resistance.
Per AACN hemodynamic monitoring guidelines, CVP combined with arterial pressure helps
differentiate shock etiologies.
Q2: A patient with a pulmonary artery catheter shows the following pressures: PAP 45/25
mmHg, PAOP (wedge) 18 mmHg, CVP 12 mmHg. Which condition is most likely?
A. Hypovolemia
B. Left ventricular failure [CORRECT]
C. Pulmonary embolism
D. Right ventricular infarction
Correct Answer: B
Rationale: Elevated PAOP (18 mmHg, normal 6-12) indicates elevated left ventricular end-
diastolic pressure/left atrial pressure, consistent with left heart failure. The elevated CVP (12
,2
mmHg) suggests biventricular involvement or fluid overload. PAP elevation reflects back
pressure from left heart. Hypovolemia (Option A) would show low pressures. Pulmonary
embolism (Option C) typically shows elevated PAP with normal/low PAOP. RV infarction
(Option D) shows high CVP with normal/low PAOP (dissociation). These waveforms are
essential BKAT-10 hemodynamic monitoring competencies.
Q3: The nurse is monitoring a patient post-CABG with a PA catheter. The cardiac output is 4.5
L/min, systemic vascular resistance (SVR) is 1800 dynes/sec/cm⁻⁵ (elevated), and the patient has
cool extremities with decreased urine output. Which intervention is priority?
A. Administer vasodilator to decrease afterload [CORRECT]
B. Administer fluid bolus
C. Increase inotropic support
D. Administer diuretic
Correct Answer: A
Rationale: Post-CABG patients often have elevated SVR (normal 800-1200) due to stress
response, hypothermia, or pain. High afterload increases myocardial oxygen demand and reduces
cardiac output. Vasodilators (nitroprusside, nicardipine) reduce afterload, improving cardiac
output and tissue perfusion. Fluids (Option B) would worsen preload if PAOP is adequate. More
inotropes (Option C) increase myocardial oxygen demand unnecessarily. Diuretics (Option D)
reduce preload inappropriately. AACN guidelines emphasize afterload reduction in post-cardiac
surgery patients with elevated SVR.
Q4: A patient with an ICD delivers a shock while the nurse is providing care. What is the nurse's
immediate action?
A. Remove all monitoring equipment
B. Ensure safety, assess patient rhythm and response, and document the event [CORRECT]
C. Apply magnesium sulfate immediately
D. Turn off the ICD
Correct Answer: B
Rationale: ICD shocks indicate detected ventricular tachyarrhythmia. Immediate nursing
actions: ensure personal safety (don't touch patient during shock), assess patient consciousness
and rhythm post-shock, provide supportive care, and document event for electrophysiology
follow-up. Magnesium (Option C) is for specific arrhythmias (torsades), not indicated here.
Turning off ICD (Option D) requires physician order and magnet application—never done
,3
without indication. Removing monitors (Option A) loses critical data. Per AACN and device
guidelines, assessment and documentation are priorities.
Q5: A patient presents with ST-segment elevation in leads V1-V4, chest pain, and hypotension.
Which complication should the nurse monitor for most carefully?
A. Pericarditis
B. Anterior wall STEMI with risk for cardiogenic shock [CORRECT]
C. Inferior wall MI
D. Right bundle branch block
Correct Answer: B
Rationale: ST elevation V1-V4 indicates left anterior descending (LAD) artery occlusion—
anterior wall STEMI. This territory affects large myocardial mass with high risk for: cardiogenic
shock, malignant dysrhythmias, and heart failure. The hypotension suggests hemodynamic
compromise. Pericarditis (Option A) shows diffuse ST elevation. Inferior MI (Option C) affects
leads II, III, aVF. RBBB (Option D) is a conduction abnormality, not the primary diagnosis.
AACN acute coronary syndrome protocols prioritize hemodynamic monitoring for anterior
STEMI.
Q6: A patient with heart failure has the following mixed venous oxygen saturation (SvO₂)
readings: 55%. What does this indicate?
A. Adequate tissue oxygenation
B. Decreased oxygen delivery or increased oxygen consumption [CORRECT]
C. Hyperdynamic state
D. Sepsis with peripheral shunting
Correct Answer: B
Rationale: Normal SvO₂ is 60-80%. A value of 55% indicates inadequate oxygen delivery
relative to demand—causes include: low cardiac output, anemia, hypoxemia, or increased
metabolic demand (fever, shivering, agitation). This warrants investigation of cardiac output,
hemoglobin, and oxygenation. Adequate oxygenation (Option A) would show normal/high SvO₂.
Hyperdynamic sepsis (Options C, D) typically shows elevated SvO₂ (>80%) due to
maldistribution. Per BKAT-10, SvO₂ interpretation is a core hemodynamic monitoring
competency.

Q7: During temporary pacemaker insertion, the patient develops hiccups with each pacing spike.
What is the most likely cause?
A. Normal response to pacing
B. Diaphragmatic stimulation from lead malposition or high output [CORRECT]
C. Patient anxiety
D. Esophageal intubation
Correct Answer: B
Rationale: Hiccups during pacing indicate phrenic nerve/diaphragmatic stimulation—caused by:
(1) lead malposition (ventricular lead near phrenic nerve), (2) high pacing output capturing
diaphragm, or (3) perforation. This requires immediate assessment: check chest X-ray for lead
position, reduce output if capture threshold allows, or reposition lead. Not normal (Option A).
Anxiety (Option C) doesn't cause synchronous hiccups. Esophageal intubation (Option D) is
unrelated to pacing. This is a classic BKAT troubleshooting scenario.
Q8: A patient with aortic dissection (Stanford Type A) presents with BP 180/110 mmHg and
heart rate 95 bpm. Which medication combination is priority?
A. Nitroglycerin and morphine
B. IV beta-blockade (esmolol or labetalol) followed by vasodilator if needed [CORRECT]
C. Nitroprusside alone
D. Heparin bolus
Correct Answer: B
Rationale: Aortic dissection management prioritizes: (1) reduce shear stress (dP/dt) with beta-
blockade first—decreases heart rate and contractility, (2) then add vasodilators if BP remains
elevated. Beta-blockade before vasodilation prevents reflex tachycardia that increases shear
stress. Nitroprusside alone (Option C) causes reflex tachycardia. Heparin (Option D) is
contraindicated until dissection type/surgical plan confirmed—anticoagulation can cause
bleeding in Type A requiring surgery. Per ACC/AHA and AACN guidelines, beta-blockade is
mandatory first step.
Q9: A patient post-mitral valve replacement develops sudden severe respiratory distress,
hypotension, and muffled heart sounds. Which complication is suspected?
A. Pneumonia
B. Cardiac tamponade [CORRECT]
C. Pulmonary embolism
D. Acute MI
