Q1.
A patient with septic shock has a cardiac index of 2.1 L/min/m², systemic vascular
resistance index of 1200 dyn-sec-cm-m², and pulmonary artery occlusion pressure of 8
mm Hg. Despite norepinephrine at 0.5 mcg/kg/min, mean arterial pressure remains 55 mm
Hg. What is the most appropriate next intervention?
A. Add vasopressin at 0.04 units/min B. Increase norepinephrine to 1 mcg/kg/min
C. Administer a 500 mL crystalloid bolus D. Start dobutamine at 5 mcg/kg/min
Correct: C - Administer a 500 mL crystalloid bolus
Rationale:The low PAOP (8) and low CI indicate hypovolemia; fluid is first-line before adding
or escalating vasopressors. Vasopressin is a second-line agent, dobutamine is used for low
cardiac output with adequate preload, and increasing norepinephrine alone won't correct
hypovolemia.
Q2.
During volume-controlled ventilation, the airway pressure waveform shows a sudden
increase in peak inspiratory pressure with no change in plateau pressure. Which condition
is most likely?
A. Bronchospasm B. Tension pneumothorax
C. Mainstem bronchus intubation D. Pulmonary edema
Correct: A - Bronchospasm
Rationale:An increase in peak pressure with unchanged plateau suggests increased airway
resistance, as in bronchospasm. Tension pneumothorax and mainstem intubation increase
both peak and plateau pressures; pulmonary edema reduces compliance, raising plateau
pressure as well.
Q3.
A patient receiving continuous sedation with propofol develops metabolic acidosis with
elevated lactate and elevated triglycerides. Which alternative sedation agent is most
appropriate?
A. Dexmedetomidine B. Midazolam

CARE Nursing CCRN Adult Graduate
C. Fentanyl D. Ketamine
Correct: A - Dexmedetomidine
Rationale:Propofol infusion syndrome is suspected; dexmedetomidine provides sedation
without the metabolic risks. Midazolam may cause accumulation, fentanyl is an analgesic,
and ketamine is not ideal for prolonged sedation in this context.
Q4.
A patient with subarachnoid hemorrhage develops acute neurologic decline. Transcranial
Doppler shows mean flow velocity of 220 cm/s in the middle cerebral artery. What is the
most appropriate immediate intervention?
A. Induced hypertension and nimodipine B. Immediate intubation and hyperventilation
C. Intravenous mannitol bolus D. Emergent craniotomy
Correct: A - Induced hypertension and nimodipine
Rationale:Elevated MCA velocity indicates vasospasm; induced hypertension and nimodipine
are first-line to improve perfusion. Hyperventilation may worsen vasospasm, mannitol treats
cerebral edema, and craniotomy is for surgical lesions like aneurysm clipping, not acute
vasospasm.
Q5.
A patient with acute kidney injury and hyperkalemia (K+ 6.8 mEq/L) has an ECG showing
peaked T waves. Which intervention should be initiated first?
A. IV calcium gluconate B. IV insulin with dextrose
C. Sodium bicarbonate infusion D. Emergent hemodialysis
Correct: A - IV calcium gluconate
Rationale:Calcium stabilizes the myocardium immediately, protecting against arrhythmias.
Insulin/glucose shifts potassium intracellularly, bicarbonate is less effective, and dialysis takes
time to arrange.
Q6.
A patient with diabetic ketoacidosis has a serum potassium of 2.9 mEq/L. Which
potassium replacement strategy is most appropriate before starting insulin therapy?
A. Hold insulin until potassium is >3.3 B. Administer insulin immediately with
mEq/L potassium in IV fluids
C. Give 40 mEq oral potassium D. Start insulin and monitor potassium
closely
