An arterial blood gas sample shows pH 7.36, PaCO2 50 mmHg and HCO3 28 mEq/L. How should the nurse interpret these results?
Correct answer: C. Compensated respiratory acidosis
- A. Uncompensated respiratory alkalosis
- B. Partially compensated metabolic acidosis
- C. Compensated respiratory acidosis
- D. Uncompensated metabolic alkalosis
Explanation
The raised PaCO2 indicates respiratory acidosis, while the raised bicarbonate shows renal compensation. The pH has returned to the normal range, so the respiratory acidosis is compensated rather than uncompensated.
