A patient's blood gases show a pH of 7.53 and bicarbonate level of 36 mEq/L. The nurse prepares to treat this patient for which acid-base disorder?
1. Respiratory acidosis
2. Metabolic acidosis
3. Respiratory alkalosis
4. Metabolic alkalosis
4
Rationale 1: Respiratory acidosis is consistent with a pH lower than 7.35.
Rationale 2: Metabolic acidosis is consistent with pH lower than 7.35.
Rationale 3: Respiratory alkalosis is associated with a pH greater than 7.45 and a PaCO2 of less than 35 mmHG. It is caused by respiratory-related conditions.
Rationale 4: When the patient is in metabolic alkalosis, arterial blood gases (ABGs) show a pH greater than 7.45 and bicarbonate level greater than 26 mEq/L.
