,Section A - Management OF CARE
Q1.
A patient with septic shock remains hypotensive despite adequate fluid resuscitation.
Which hemodynamic profile best supports the addition of norepinephrine over further
fluid boluses?
A. Cardiac index 2.8 L/min/m², systemic B. Cardiac index 4.2 L/min/m², systemic
vascular resistance 600 dynes-sec-cm, vascular resistance 900 dynes-sec-cm,
central venous pressure 12 mm Hg central venous pressure 8 mm Hg
C. Cardiac index 1.9 L/min/m², systemic D. Cardiac index 3.5 L/min/m², systemic
vascular resistance 1400 dynes-sec-cm, vascular resistance 450 dynes-sec-cm,
central venous pressure 6 mm Hg central venous pressure 14 mm Hg
Correct: A - Cardiac index 2.8 L/min/m², systemic vascular resistance 600 dynes-sec-cm,
central venous pressure 12 mm Hg
Rationale:In septic shock, vasoplegia with low SVR and normal/high cardiac output is the
hallmark. Option A shows low SVR (600) with adequate CI and filling pressures, indicating
vasodilation that would respond to norepinephrine. Option D also has low SVR but higher
CVP and CI, suggesting possible fluid overload and need for inodilator rather than pure
vasopressor. Option C indicates cardiogenic shock (low CI, high SVR). Option B shows
adequate SVR and CI, not requiring pressor.
Q2.
A patient on vancomycin and piperacillin-tazobactam develops acute kidney injury (AKI)
with a serum creatinine rise from 0.9 to 2.1 mg/dL over 48 hours. Which intervention is
most appropriate to minimize further nephrotoxicity?
A. Discontinue piperacillin-tazobactam, B. Continue both antibiotics, add IV
continue vancomycin, and monitor trough furosemide to maintain urine output
levels
C. Switch vancomycin to daptomycin and D. Switch piperacillin-tazobactam to
continue piperacillin-tazobactam cefepime and continue vancomycin with
therapeutic drug monitoring
Correct: D - Switch piperacillin-tazobactam to cefepime and continue vancomycin with
therapeutic drug monitoring
Page 3
, Section A - Management OF CARE
Rationale: Combination of vancomycin and piperacillin-tazobactam is associated with higher
AKI risk, especially when vancomycin troughs are elevated. The best action is to remove the
nephrotoxic combination while preserving coverage: cefepime replaces
piperacillin-tazobactam, and vancomycin is continued with TDM. Discontinuing piperacillin
alone (A) leaves vancomycin as the culprit; furosemide does not prevent tubular injury;
daptomycin is inactivated by surfactant and not ideal for pneumonia.
Q3.
In a patient with acute respiratory distress syndrome (ARDS) on volume-controlled
ventilation, plateau pressure is 32 cm HO and PaO/FiO ratio is 150. Which ventilation
strategy is most appropriate to improve oxygenation while limiting further lung injury?
A. Increase PEEP to 15 cm HO and reduce B. Increase tidal volume to 8 mL/kg ideal
tidal volume to 4 mL/kg ideal body weight body weight and keep PEEP at 10 cm HO
C. Switch to pressure-controlled ventilation D. Decrease respiratory rate to lower minute
with peak pressure 35 cm HO ventilation and allow permissive
hypercapnia
Correct: A - Increase PEEP to 15 cm HO and reduce tidal volume to 4 mL/kg ideal body
weight
Rationale:In ARDS, lung-protective ventilation (low tidal volume 4-6 mL/kg IBW) and higher
PEEP improve oxygenation and reduce ventilator-induced lung injury. Plateau pressure
should be kept 30 cm HO. Option A achieves both. Increasing tidal volume (B) worsens
injury; pressure control with high peak pressure (C) may still cause overdistension;
decreasing rate (D) doesn't address oxygenation.
Q4.
Which electrocardiographic finding is most indicative of hyperkalemia and warrants
immediate intervention?
A. Prolonged PR interval with a normal QRS B. Tall, peaked T waves with a widened
duration QRS complex
C. ST-segment depression with inverted T D. Shortened QT interval with prominent U
waves waves
Correct: B - Tall, peaked T waves with a widened QRS complex
Rationale:Hyperkalemia classically produces tall, peaked T waves, followed by QRS
widening, loss of P waves, and sine wave pattern. This requires emergent treatment.
Prolonged PR (A) is seen in first-degree block, not specific; ST depression (C) indicates
ischemia; short QT with U waves (D) is seen in hypokalemia, not hyperkalemia.
