A 60-year-old male patient is admitted to the medical unit with a bowel obstruction causing him to vomit frequently
What is the correct interpretation of the most recent arterial blood gas values for this patient: pH = 7.51; PaCO2 = 43 mm Hg; and HCO3– = 34 mEq/L?
a. Respiratory acidosis c. Respiratory alkalo-sis
b. Metabolic acidosis d. Metabolic alkalosis
ANS: D
The increased pH indicates alkalosis, and the HCO3– is increased, reflecting a primary metabolic problem most likely caused by the patient's vomiting.
