Final answer:
Reinforce that the client should change the infusion site every 2 to 3 days, disconnect the pump during showering, and avoid exposing the insulin or pump to extreme temperatures to manage blood glucose levels effectively in type 1 diabetes.
Step-by-step explanation:
The nurse should emphasize to the client with type 1 diabetes mellitus using a subcutaneous insulin infusion pump certain key points to ensure effective management of their condition. It is critical to change the infusion site every 2 to 3 days, not weekly, to prevent infection and ensure proper absorption of insulin. The insulin vial that is in use may be kept at room temperature to avoid cold insulin injections, however, any additional vials should be stored in the refrigerator. The student should also disconnect the pump during showering to prevent damage to the device as it is not typically waterproof. Moreover, the pump should not be exposed to direct sunlight as extreme temperatures can affect the pump's functionality and the insulin's stability but rather it should be kept at room temperature and out of direct sunlight. Understanding these factors is essential in the management of blood glucose levels to maintain them within the target range.
