Question 1
A 55-year-old man in the SICU with septic shock has a central
venous oxygen saturation (ScvO2) of 55% after initial fluid
resuscitation of 30 mL/kg. His hemoglobin is 8.5 g/dL, and mean
arterial pressure (MAP) is 65 mmHg on norepinephrine. What is
the most appropriate next step?
A. Transfuse packed red blood cells to goal hemoglobin >10
g/dL
B. Start dobutamine
C. Increase norepinephrine dose
1
,D. Administer hydrocortisone
E. Repeat fluid bolus
Answer: B
*Rationale: Persistent low ScvO2 (<70%) after adequate fluids
and MAP indicates inadequate oxygen delivery. Dobutamine
increases cardiac output. Transfusion is indicated if Hgb <7 g/dL
(or <8 with cardiac disease).*
Question 2
A patient is intubated with the following ABG: pH 7.21, PaCO2
60 mmHg, PaO2 85 mmHg, HCO3 24 mEq/L on FiO2 0.5. The
ventilator rate is 12 breaths/min. What is the most appropriate
change?
A. Increase FiO2 to 0.6
B. Increase rate to 18 breaths/min
C. Increase tidal volume from 450 mL to 550 mL
2
,D. Add PEEP of 10 cm H2O
E. Change to pressure control ventilation
Answer: B
Rationale: Acute respiratory acidosis (pH <7.30, PaCO2 >45,
normal HCO3) requires increased minute ventilation. Increasing
rate is safer than increasing tidal volume (barotrauma risk).
Question 3
Which of the following is a contraindication to therapeutic
hypothermia after cardiac arrest?
A. Time to ROSC of 40 minutes
B. Initial rhythm of ventricular fibrillation
C. Pregnancy
D. Age >75 years
E. Pre-arrest GCS of 14
3
, Answer: C
Rationale: Pregnancy, active bleeding, severe sepsis, and
prolonged downtime >60 minutes are contraindications. VF arrest
has best outcomes with hypothermia.
Question 4
A 28-year-old man with multiple gunshot wounds receives 15
units of packed red blood cells, 10 units of platelets, and 8 units
of plasma over 6 hours. He now has oozing from his IV sites and
chest tube. Laboratory studies show: PT 18 seconds (normal 12),
PTT 45 seconds (normal 25), fibrinogen 90 mg/dL, platelets
80,000/μL. What is the most appropriate next step?
A. Give additional 2 units of platelets
B. Give cryoprecipitate
C. Give vitamin K
