A client who is taking methylprednisolone reports feeling thirsty. Which action should the nurse take first?

A. Monitor urinary output: While monitoring output is important, it does not provide immediate diagnostic information regarding the cause of the client’s thirst. It is a supportive action but not the most efficient first step to investigate potential hyperglycemia.B. Notify the healthcare provider (HCP): Notifying the HCP is appropriate if there are abnormal findings or the client’s condition worsens. However, the nurse should gather objective data—such as a blood glucose reading—before contacting the provider.C. Prepare to give insulin: Insulin should not be administered without confirmation of elevated blood glucose. Giving insulin without verifying hyperglycemia could lead to serious complications, including hypoglycemia.D. Obtain fingerstick blood glucose: Methylprednisolone, a corticosteroid, can raise blood glucose levels, and excessive thirst is a classic symptom of hyperglycemia. Checking the client’s blood glucose is the most appropriate first action to determine if elevated glucose is causing the symptom.
