ICU Board Exam Started: Jul 12, 2026 18:31 Page 1 of 1 Attempt #503 Overall: 0 / 4 questions answered Question 1 / 4 Not answered A 55-year-old with pneumonia develops respiratory failure requiring intubation. Chest X-ray shows bilateral infiltrates and PaO2/FiO2 ratio is 150. Most appropriate ventilation strategy: A. Pressure control ventilation at high pressures B. Lung-protective ventilation with low tidal volumes (6 mL/kg) C. High-frequency oscillatory ventilation D. Spontaneous breathing trial E. Immediate extubation Show Answer & Explanation Correct Answer: B Explanation: Lung-protective ventilation reduces mortality in ARDS and should be initiated in all mechanically ventilated patients.

Most appropriate next step: A. Continue fluids only B. Add vasopressor to maintain MAP >65 mmHg C. Reduce fluid administration D. Give only antibiotics E. Discontinue all medications Show Answer & Explanation Correct Answer: B Explanation: Vasopressors should be initiated if hypotension persists after adequate fluid resuscitation to maintain organ perfusion.

Most appropriate initial management: A. Aggressive fluid resuscitation B. Lung-protective ventilation and conservative fluid strategy C. High FiO2 to maintain oxygen saturation >95% D. Prone positioning immediately E. Neuromuscular blockade Show Answer & Explanation Correct Answer: B Explanation: Conservative fluid strategy and lung-protective ventilation improve outcomes in ARDS.

Most appropriate next intervention: A. Increase tidal volume B. Add PEEP and consider prone positioning C. Reduce tidal volume D. Sedate and paralyze only E. Change ventilator mode Show Answer & Explanation Correct Answer: B Explanation: PEEP helps recruit alveoli and improve oxygenation; prone positioning improves outcomes in severe ARDS.
