Which action should the nurse take first when a client reports hunger, thirst, and fatigue with polyuria?

• A. Administration prescribed insulin
• B. Notify the health care provider immediately
• C. Determine client's blood glucose level
• D. Provide a peanut butter and graham cracker snack

Answer: (C)

The initial action is to determine the client's blood glucose level. Hunger, thirst, fatigue, and frequent urination can signal abnormal glycemic control, but you need an immediate, objective measurement to decide what to do next. A quick finger-stick glucose reading tells you whether the patient is hypoglycemic, hyperglycemic, or within a concerning range, and guides the appropriate intervention. If the reading is low, treat with fast-acting carbohydrate and recheck; if high, follow protocol for hyperglycemia and notify the provider as needed; if normal, continue close monitoring. Administering insulin or other actions without first knowing the glucose level could cause harm or unnecessary delays.
