EXAM CHEAT TEST WITH ALL CORRECT
ANSWERS
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 Correct AnswerA. Acute respiratory
distress syndrome

On admission, your patient's arterial blood gas on room air is: pH
7.23, PaCO2 55, PaO2 90, HCO3 30. The correct arterial blood
gas interpretation is:
A. Uncompensated metabolic acidosis
B. Uncompensated respiratory alkalosis
C. Uncompensated respiratory acidosis
D. Uncompensated metabolic alkalosis Correct AnswerC.
Uncompensated respiratory acidosis
