Target Audience: Experienced critical care nurses, CCRN candidates, and ICU
professionals seeking advanced certification and clinical competency validation
SECTION ONE: Hemodynamic Monitoring and
Cardiovascular Critical Care (Questions 1–25)
Question 1
A patient in the ICU who is 2 days post-cardiac surgery develops a sudden drop in
cardiac output, increased central venous pressure (CVP), and muffled heart sounds.
What is the most appropriate immediate nursing action?
A. Administer a 500 mL bolus of normal saline
B. Prepare for emergency pericardiocentesis
C. Increase the norepinephrine infusion rate
D. Obtain a 12-lead ECG
-detailed answer 100% correct :- B
Rationale: The triad of sudden hypotension, elevated CVP, and muffled heart sounds
(Beck's triad) is classic for cardiac tamponade, a life-threatening complication following
cardiac surgery. Emergency pericardiocentesis is the definitive intervention. Fluid bolus
would not address the compressive fluid in the pericardial space, and increasing
vasopressors would be temporizing at best.
Question 2
Which hemodynamic parameter is the most accurate indicator of left ventricular
preload?
, 3
A. Central venous pressure (CVP)
B. Pulmonary artery wedge pressure (PAWP)
C. Systemic vascular resistance (SVR)
D. Cardiac output (CO)
-detailed answer 100% correct :- B
Rationale: PAWP (also called pulmonary capillary wedge pressure) reflects left
ventricular end-diastolic pressure and is the most direct measure of left ventricular
preload. CVP reflects right ventricular preload, SVR measures afterload, and CO
measures overall cardiac function, not preload specifically.
Question 3
A patient with severe ARDS is on mechanical ventilation with PEEP of 15 cm H₂O. The
nurse notes a sudden drop in blood pressure from 110/70 to 82/50 mmHg and
decreased breath sounds on the right side. What is the priority intervention?
A. Administer IV bolus of normal saline
B. Notify the provider immediately for possible chest tube insertion
C. Increase the PEEP to 18 cm H₂O
D. Place the patient in high Fowler's position
-detailed answer 100% correct :- B
Rationale: The sudden hypotension and decreased breath sounds suggest tension
pneumothorax, a life-threatening complication of high PEEP mechanical ventilation. This
requires immediate provider notification for chest tube insertion. Fluid bolus won't
address the underlying problem, increasing PEEP would worsen the pneumothorax, and
positioning does not treat tension pneumothorax.

Question 4
The nurse is caring for a patient with a pulmonary artery catheter. Which finding
indicates the catheter has migrated into a wedged position and requires immediate
repositioning?
A. PAWP reading of 8 mmHg
B. Continuous pulmonary artery waveform with loss of respiratory variation
C. Wedged waveform with a PAWP tracing that does not return to pulmonary artery
waveform
D. CVP of 12 mmHg
-detailed answer 100% correct :- C
Rationale: A pulmonary artery catheter that remains in a wedged position (continuous
wedge tracing) indicates the balloon is inflated or the catheter has migrated distally.
This can cause pulmonary infarction and requires immediate repositioning.
Question 5
A patient has a mixed venous oxygen saturation (SvO₂) of 50%. Which interpretation is
most accurate?
A. The patient is adequately oxygenated
B. The patient is not being adequately oxygenated and may be hypovolemic
C. The patient has normal oxygen extraction
D. The patient requires immediate blood transfusion
-detailed answer 100% correct :- B
