The nurse provides care to a patient admitted with a respiratory disorder. Which laboratory finding is most concerning?
Oxygen saturation 96%
Blood pH 7.32
Hemoglobin level 12 mg/dL
PaO2 80 mm Hg
The Correct Answer is B
A. Oxygen saturation 96%. This is a normal oxygen saturation level, so it is not a concern.
B. Blood pH 7.32. A pH below 7.35 indicates acidosis, which is concerning in a patient with a respiratory disorder, as it may indicate respiratory failure.
C. Hemoglobin level 12 mg/dL. This is a normal hemoglobin level for most adults and does not indicate a critical problem.
D. PaO2 80 mm Hg. While slightly lower than the normal range (normal is 80–100 mm Hg), this is not the most concerning finding.

Explanation
A. Temperature: While temperature monitoring is important, hypothermia is not the most immediate concern after general anesthesia.
B. Heart rate: Although heart rate should be monitored, it is not the first priority in assessing an anesthetized patient.
C. Respirations: Airway and breathing are the top priorities in the PACU. General anesthesia can depress respiratory function, increasing the risk of airway obstruction or hypoventilation. Ensuring adequate ventilation is the first step in assessment.
D. Blood pressure: Blood pressure is important but secondary to airway and breathing in the initial assessment.
