FFICM Patient Assessment and Evaluation 2

Question 1

A 68-year-old ICU patient has a urine output of 0.3 mL/kg/hr for 8 hours. Which KDIGO stage of acute kidney injury does this represent?

Accepted Answer

Stage 1

Answer

KDIGO Stage 1 AKI includes urine output <0.5 mL/kg/hr for 6–12 hours.

Question 2

When assessing a mechanically ventilated patient, which parameter best reflects respiratory system compliance?

Accepted Answer

Plateau pressure minus PEEP divided by tidal volume

Answer

Static compliance = tidal volume / (plateau pressure − PEEP), reflecting the elastic properties of the respiratory system.

Question 3

A patient's arterial blood gas shows pH 7.22, PaCO₂ 50 mmHg, HCO₃⁻ 20 mEq/L. What is the primary acid-base disorder?

Accepted Answer

Respiratory acidosis with metabolic acidosis

Answer

Expected HCO₃⁻ for acute respiratory acidosis with PaCO₂ 50 would be ~24 mEq/L; the low HCO₃⁻ indicates a concurrent metabolic acidosis.

Question 4

Which physical examination finding is most specific for cardiac tamponade in a critically ill patient?

Accepted Answer

Pulsus paradoxus >10 mmHg

Answer

Pulsus paradoxus >10 mmHg is the most specific bedside sign of hemodynamically significant tamponade.

Question 5

A SOFA score is being calculated for a patient with PaO₂/FiO₂ of 180 mmHg requiring mechanical ventilation. What respiratory SOFA subscore should be assigned?

Accepted Answer

3

Answer

A PaO₂/FiO₂ of 100–199 on respiratory support corresponds to a respiratory SOFA subscore of 3.
