A patient's arterial blood gas results are pH 7.48, PaCO2 30 mmHg and HCO3 23 mEq/L. How should the nurse interpret these results?

Correct answer: A. Uncompensated respiratory alkalosis

  • A. Uncompensated respiratory alkalosis
  • B. Uncompensated respiratory acidosis
  • C. Partially compensated metabolic alkalosis
  • D. Fully compensated metabolic acidosis

Explanation

The high pH shows alkalemia and the low PaCO2 identifies a respiratory cause. The normal bicarbonate indicates that significant metabolic compensation has not developed, so this is uncompensated respiratory alkalosis.
