Critical CARE Scenario & WITH Rationales A University
Q1.
A patient with septic shock and acute respiratory distress syndrome (ARDS) has a
PaO2/FiO2 ratio of 90 on volume-controlled ventilation. Despite optimizing PEEP and
recruitment maneuvers, oxygenation remains refractory. Which intervention is most likely
to improve oxygenation while minimizing additional lung injury?
A. Increase FiO2 to 1.0 and maintain current B. Initiate prone positioning for at least 16
ventilator settings hours per day
C. Switch to airway pressure release D. Administer a neuromuscular blocking
ventilation (APRV) with a high PEEP agent infusion for 48 hours
Correct: B - Initiate prone positioning for at least 16 hours per day
Rationale:Prone positioning improves ventilation-perfusion matching and reduces mortality in
severe ARDS (PaO2/FiO2 < 150) when applied for 16 hours/day. Increasing FiO2 alone does
not address underlying shunt and risks oxygen toxicity. APRV and neuromuscular blockade
are adjuncts but are not the primary evidence-based intervention for refractory hypoxemia in
this context.
Q2.
A patient with a history of chronic kidney disease (CKD) and heart failure is admitted with
fluid overload. The provider prescribes furosemide 80 mg IV push. Which laboratory value,
if present, would most likely predict diuretic resistance and require a change in
management?
A. Serum albumin 2.8 g/dL B. Serum sodium 128 mEq/L
C. Serum creatinine 3.2 mg/dL D. Urine sodium 25 mEq/L after furosemide
administration
Correct: D - Urine sodium 25 mEq/L after furosemide administration
Rationale:A spot urine sodium <50 mEq/L after a loop diuretic indicates inadequate
natriuresis and diuretic resistance, requiring higher doses, continuous infusion, or addition of
a thiazide. Hypoalbuminemia, hyponatremia, and elevated creatinine are common but do not
directly confirm resistance to the administered dose.

Q3.
In a patient with diabetic ketoacidosis (DKA) and a serum potassium of 3.2 mEq/L on
admission, which sequence of interventions is most appropriate?
A. Start insulin infusion immediately and B. Administer potassium replacement before
recheck potassium in 2 hours starting insulin infusion
C. Give sodium bicarbonate to correct D. Begin normal saline at 500 mL/hr and
acidosis before insulin insulin only after potassium is >4.0
Correct: B - Administer potassium replacement before starting insulin infusion
Rationale:Insulin drives potassium intracellularly, worsening hypokalemia and risking fatal
arrhythmias. Potassium must be repleted to a safe level (typically >3.3 mEq/L) before
initiating insulin. Bicarbonate is not first-line and is reserved for severe acidosis with pH <6.9.
Rapid saline alone does not correct hyperglycemia or acidosis.
Q4.
Which finding in a patient with acute pancreatitis best predicts the development of
persistent organ failure and a need for intensive care admission?
A. Serum lipase level >3 times the upper B. Presence of pancreatic necrosis on
limit of normal contrast-enhanced CT within 72 hours
C. Blood urea nitrogen (BUN) rising from 15 D. Elevated C-reactive protein (CRP) of 150
to 25 mg/dL at 24 hours mg/L at 48 hours
Correct: C - Blood urea nitrogen (BUN) rising from 15 to 25 mg/dL at 24 hours
Rationale:A rising BUN at 24 hours is a validated marker of persistent systemic inflammatory
response and predicts severe pancreatitis, organ failure, and mortality. Lipase elevation
confirms diagnosis but not severity. CT findings are often not definitive early. CRP >150 at 48
hours is less specific and later.
Q5.
A patient with a large pulmonary embolism develops hypotension and signs of obstructive
shock. Which intervention is contraindicated in this setting?
A. Administration of a bolus of 500 mL B. Systemic thrombolytic therapy
isotonic crystalloid
C. Mechanical thrombectomy via catheter D. Initiation of vasopressors such as
norepinephrine
Correct: A - Administration of a bolus of 500 mL isotonic crystalloid
