Multisystem Critical Care Competency Assessment for Expert-Level ICU Nursing Practice in
Complex, High-Acuity Clinical Environments
, 2
Total Questions: 150 Multiple-Choice Questions
Difficulty Level: Advanced to Expert (Designed to challenge experienced critical care nurses with
complex, nuanced, and multi-faceted clinical scenarios)
Target Audience: Seasoned ICU nurses, CCRN-certified professionals, critical care educators, and
advanced practice nurses seeking validation of expert-level clinical judgment, prioritization
skills, and evidence-based practice in high-acuity critical care settings
SECTION ONE: Advanced Hemodynamic Monitoring and Cardiovascular Critical Care
(Questions 1–20)
Question 1
A 68-year-old male patient, 72 hours post-cardiac surgery, presents with the following
hemodynamic profile: cardiac output (CO) 3.8 L/min, cardiac index (CI) 1.9 L/min/m²,
pulmonary artery wedge pressure (PAWP) 28 mmHg, central venous pressure (CVP) 18 mmHg,
systemic vascular resistance (SVR) 1,850 dynes/sec/cm⁻⁵, and mixed venous oxygen saturation
(SvO₂) 48%. The patient is on norepinephrine 0.5 mcg/kg/min and dobutamine 7.5 mcg/kg/min.
Which of the following interventions is most appropriate?
A. Increase dobutamine to optimize cardiac contractility
B. Increase norepinephrine to improve systemic vascular resistance
C. Initiate intra-aortic balloon pump (IABP) counterpulsation
D. Administer a 500 mL normal saline bolus to increase preload
-detailed answer 100% correct :- C
Rationale: This patient exhibits cardiogenic shock with severe pump failure (CI < 2.0, PAWP > 24,
elevated CVP, elevated SVR, SvO₂ < 50%) despite maximal inotropic and vasopressor support.
IABP is indicated to reduce afterload, enhance coronary perfusion, and improve myocardial
oxygen supply-demand balance. Increasing dobutamine may precipitate arrhythmias or
myocardial ischemia; increasing norepinephrine would worsen afterload; and fluid resuscitation
is contraindicated in the setting of elevated filling pressures (PAWP 28 mmHg).
Question 2
A patient with acute decompensated heart failure (ADHF) and preserved ejection fraction
(HFpEF) is admitted to the ICU with severe pulmonary edema. The patient is hypertensive (BP
195/110 mmHg) and tachycardic (HR 115 bpm). Which initial vasoactive therapy is most
appropriate?
, 3
A. Nitroglycerin infusion
B. Sodium nitroprusside infusion
C. Dobutamine infusion
D. Milrinone infusion
-detailed answer 100% correct :- A
Rationale: In HFpEF with hypertensive emergency, afterload reduction is paramount.
Nitroglycerin provides preload reduction (venous dilation) with some afterload reduction.
Sodium nitroprusside, while effective for afterload reduction, may cause coronary steal and is
less preferred in HFpEF. Dobutamine and milrinone are inotropes that increase myocardial
oxygen demand and are generally reserved for reduced ejection fraction HF with cardiogenic
shock.
Question 3
A patient with a pulmonary artery catheter exhibits the following pattern: the PA waveform is
present but demonstrates progressive loss of the dicrotic notch, with the diastolic pressure
trend increasing from 8 mmHg to 18 mmHg over 4 hours. The patient's oxygenation has
deteriorated, and the chest X-ray shows new bilateral infiltrates. What is the most likely
diagnosis?
A. Pulmonary embolism
B. Acute respiratory distress syndrome (ARDS)
C. Left ventricular failure with worsening pulmonary edema
D. Pulmonary artery catheter migration
-detailed answer 100% correct :- C
Rationale: Progressive elevation of PA diastolic pressure (which correlates with PAWP in the
absence of pulmonary hypertension) indicates increasing left ventricular filling pressures,
consistent with worsening left ventricular failure. This is further supported by worsening
oxygenation and new bilateral infiltrates. Pulmonary embolism typically presents with elevated
PA pressures but sudden onset, and ARDS would not explain the progressive hemodynamic
changes.
Question 4
A 72-year-old female patient with end-stage renal disease on hemodialysis develops refractory
hypotension during dialysis. She is admitted to the ICU with BP 78/40 mmHg, HR 112 bpm, and
, 4
JVD distended. Bedside echocardiography reveals a large pericardial effusion with signs of right
ventricular diastolic collapse. What is the most appropriate immediate intervention?
A. Administer 1 liter normal saline bolus
B. Start norepinephrine infusion
C. Prepare for emergency pericardiocentesis
D. Administer epinephrine 1 mg IV push
-detailed answer 100% correct :- C
Rationale: The combination of refractory hypotension, JVD, and echocardiographic evidence of
right ventricular diastolic collapse in a patient with renal failure indicates cardiac tamponade, a
life-threatening emergency. Emergency pericardiocentesis is the definitive treatment. Fluid
resuscitation and vasopressors are temporizing measures at best, and epinephrine is not
appropriate for tamponade.
Question 5
A patient with severe aortic stenosis is admitted with chest pain, pulmonary edema, and
hypotension. Which medication is strictly contraindicated in this patient?
A. Norepinephrine
B. Phenylephrine
C. Nitroglycerin
D. Dobutamine
-detailed answer 100% correct :- C
Rationale: Nitroglycerin causes venodilation, reducing preload. In severe aortic stenosis, cardiac
output is fixed and preload-dependent. Nitroglycerin can precipitate catastrophic hypotension
and cardiovascular collapse. Vasopressors like norepinephrine and phenylephrine are actually
indicated to maintain coronary perfusion pressure, and dobutamine may be used cautiously for
inotropic support.
Question 6
A patient is receiving intra-aortic balloon pump (IABP) therapy with 1:1 augmentation. The
nurse notes the following arterial waveform: balloon inflates at the dicrotic notch and deflates
just before systole. The augmented diastolic pressure is 140 mmHg, and the peak systolic
pressure is 90 mmHg. What is the most appropriate nursing action?
