Question Of The Day, The Nursing Process
Q. A client has the following arterial blood gas values: pH, 7.30; PaO2, 89 mm Hg; PaCO2, 50 mm Hg; and HCO3–, 26 mEq/L. Based on these values, the nurse should suspect which condition?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

Correct Answer: A
Explanation: This client has a below-normal (acidic) blood pH value and an above-normal partial pressure of arterial carbon dioxide (PaCO2) value, indicating respiratory acidosis. In respiratory alkalosis, the pH value is above normal and the PaCO2 value is below normal. In metabolic acidosis, the pH and bicarbonate (HCO3–) values are below normal. In metabolic alkalosis, the pH and HCO3– values are above normal.
