A patient who is 72 hours postoperative repair of a bowel obstruction
suddenly demonstrates shortness of breath and his respiratory rate increases
from 22 to 45/min. His SpO2 went from 95% to 88% acutely. An arterial
blood gas sample obtained while the patient is receiving oxygen via a nasal
cannula at 6L/min reveals the following results:
pH 7.40
pCO2 27
pO2 50
A chest x-ray is obtained and a "ground-glass-like appearance" is reported.
Auscultation of the lungs reveals diffuse crackles that were not present
previously.
The findings described above should lead the nurse to believe that the
patient has:
A. Acute respiratory distress syndrome
B. A pulmonary embolus
C. A spontaneous pneumothorax
D. Aspiration pneumonia
