Question 1 of 5

A nurse is reviewing the ABG results for a client. The client's results are pH 7.47,PaCO2 30 mm Hg HCO3 25 mEq/L,and SaO2 90%. The nurse should identify that the client is experiencing which of the following acid-base imbalances?

Correct Answer: C

Rationale: The correct answer is C: Metabolic alkalosis. The pH is elevated (alkalotic) at 7.47, indicating an alkalotic state. The HCO3 level is also elevated at 25 mEq/L, which is consistent with metabolic alkalosis. The PaCO2 level is low at 30 mm Hg, indicating a compensatory respiratory response to the alkalotic state. The SaO2 level of 90% is not directly related to acid-base balance but may be affected by the underlying condition causing metabolic alkalosis.

Incorrect choices:
A: Metabolic acidosis - pH would be <7.35, HCO3 would be low.
B: Respiratory acidosis - pH would be <7.35, PaCO2 would be high.
D: Respiratory alkalosis - pH would be >7.45, PaCO2 would be low.
In summary, the client's ABG results indicate metabolic alkalosis based on the elevated pH and
