Arterial blood gas levels are obtained for the client

84. Arterial blood gas levels are obtained for the client. If the client’s results are pH 7.48, CO2 42 mm Hg,
and HCO3 32 mEq/L, the client is exhibiting which one of the following acid- base imbalances?
A. metabolic alkalosis
B. respiratory acidosis
C. metabolic acidosis
D. respiratory acidosis
ANS: A. The client’s pH is elevated at 7.48 (normal 7.35 to 7.45), the CO2 is normal at 42 mm Hg (normal 35
to 45 mm Hg), and the bicarbonate is elevated at 32 mEq/L (normal 22 to 26 mEq/L). The client is experiencing
metabolic alkalosis. In metabolic acidosis the client’s pH would be below 7.35, and the bicarbonate would be
below 22 mEq/L. In respiratory acidosis the client’s pH would be below 7.35, and the CO2 would be elevated
above 45 mm Hg. In respiratory alkalosis the client’s pH would be above 7.45, and the CO2 would be below 35
mm Hg.
