32. Two days after a cholecystectomy, a 42-year-old woman has shortness of breath. Her temperature is 37.5 C (99.5 F), blood pressure is 110/70 mm Hg, pulse is 103/min, and respirations are 24/min. There is abdominal tenderness. Examination shows no other abnormalities. An x-ray film of the chest shows minimal linear markings in the right lower lobe. Arterial blood gas analysis on 45% oxygen shows:
pH 7.41
PCO2 40 mm Hg
PO2 52 mm Hg
Which of the following is the most likely explanation for her hypoxia?
A) Acute respiratory distress syndrome
B) Atelectasis
C) Congestive heart failure
D) Fat embolism syndrome
E) Pneumonia
F) Pneumothorax

sigh reflex along with normal deep breathing is absent in spontaneously breathing postoperative patients. the result is increased collapse of alveoli, arteriovenous shunting of blood in the pulmonary circulation, and systemic hypoxia.
