Final answer:
A client with an arterial blood gas pH of 7.48 is experiencing metabolic alkalosis.
Step-by-step explanation:
A client with an arterial blood gas pH of 7.48 is experiencing alkalosis. Alkalosis is when the blood pH is higher than the normal range (7.35-7.45). In this case, since the pH is elevated, the client is experiencing metabolic alkalosis. This means that there is an excess of bicarbonate (HCO3-) in the blood. Metabolic alkalosis can be caused by factors like vomiting or excessive use of diuretics.
