A patient with a respiratory disorder has an arterial blood gas result of pH 7.25, PaCO2 28 mmHg and HCO3 12 mEq/L. How should the nurse interpret these results?
Correct answer: A. Metabolic acidosis with respiratory compensation
- A. Metabolic acidosis with respiratory compensation
- B. Respiratory acidosis without compensation
- C. Metabolic alkalosis with respiratory compensation
- D. Respiratory alkalosis without compensation
Explanation
The low pH and low bicarbonate show metabolic acidosis, while the low PaCO2 indicates compensatory hyperventilation. The pH remains abnormal, so compensation is only partial rather than complete.
