Physiological AdaptationQuestion 225 of 2368
A client has a pH of 7.30, a PaCO2 of 52 mmHg and an HCO3 of 24 mEq/L. Which acid-base imbalance does the nurse identify?
- Respiratory alkalosis
- Respiratory acidosis
- Metabolic acidosis
- Metabolic alkalosis
Show answer
Correct answer: Respiratory acidosis
A pH below 7.35 with a PaCO2 above 45 shows respiratory acidosis. The HCO3 is normal, so the cause is not metabolic.
