A patient's arterial blood gas (ABG) values include a pH of 7.48, a PaCO2 of 38, and an HCO3- of 30. Around which acid-base imbalance would the nurse plan the patient's care?
Correct answer
B
Rationale
Metabolic alkalosis is indicated by a high pH (7.48) and elevated HCO3- (30 mEq/L), with normal PaCO2, suggesting no respiratory involvement.
