The client who has been taking glipizide for 6 months reports to the nurse that his urine has become darker since starting the medication. What is the nurse's first action?

A. While skipping meals can affect blood glucose levels, it is not a direct primary cause of DKA. In some cases, if a person with Type 1 diabetes skips a meal and does not adjust their insulin accordingly, it could lead to hyperglycemia. However, the absence of insulin is the critical factor in DKA.
B. Gastrointestinal disturbances, such as vomiting or diarrhea, can contribute to DKA by leading to dehydration and altering insulin absorption. However, they are not primary causes. The main concern is that they may cause the individual to skip insulin or not manage their diabetes effectively.
C. DKA is primarily caused by a lack of insulin, which leads to the body breaking down fat for energy instead of glucose. This process produces ketones, which can accumulate and lead to acidosis. For individuals with Type 1 diabetes, consistently taking insulin is crucial to prevent DKA.
D. An insulin overdose can lead to hypoglycemia, not DKA. When too much insulin is taken, it can cause blood glucose levels to drop too low, which is the opposite of what occurs in DKA.

A. While taking vital signs can provide useful information about the client's overall condition, it does not directly address the immediate concern of potential hypoglycemia. The priority is to assess blood glucose levels, as this will guide further actions.
B. Glucagon is used for severe hypoglycemia when the client is unable to consume glucose orally. However, before administering glucagon, it is essential to confirm hypoglycemia by checking the blood glucose level. This ensures that glucagon is only used when absolutely necessary.
C. Checking the blood glucose level will quickly determine whether the client is experiencing hypoglycemia. If the blood glucose is low, appropriate treatment (such as administering glucose or a fast-acting carbohydrate) can be initiated. If it’s within normal limits, other potential causes for the symptoms can be explored.

D. While it may be necessary to notify the physician depending on the outcome of the blood glucose reading or if the client’s condition worsens, it is not the first action. Immediate assessment of blood glucose is essential to determine the appropriate course of action.
