All the following are recognized complications of mechanical ventilation that can result from the use of high tidal volume and/or inspiratory pressure EXCEPT:

Correct Answer: D

Rationale: High tidal volume and inspiratory pressure may cause volutrauma, barotrauma, oxytrauma, and atelectotrauma, but they do not directly result in decreased surfactant production.

Correct Answer: B

Rationale: Marked tachypnea with recessions is more indicative of respiratory failure rather than circulatory failure.

Correct Answer: B

Rationale: Expiratory grunting is a compensatory mechanism in pneumonia to maintain end-expiratory lung volume and improve oxygenation, often seen in infants and young children.

Correct Answer: B

Rationale: A low Factor VII level is a poor prognostic sign in fulminant hepatitis, indicating severe hepatic dysfunction and impaired coagulation.

Correct Answer: B

Rationale: Large VSDs typically present with symptoms like heart failure and failure to thrive within 1-3 months of age.
