A nurse is caring for a client who has type 1 diabetes mellitus and reports severe ankle pain after falling off a stepstool at home. Which of the following prescriptions should the nurse clarify with the provider?

A. Incorrect. Obtaining capillary blood glucose level every 2 hr is appropriate for a client who has type 1 diabetes mellitus, but it does not address the ankle injury. B. Incorrect. Checking the neurovascular status of the client's lower extremities every hour is important for a client who has an ankle injury, but it does not require clarification with the provider. C. Correct. Applying a cold pack to the client's ankle for 30 min every hour can reduce swelling and inflammation, but it can also impair circulation and increase the risk of tissue damage in a client who has diabetes mellitus. Therefore, the nurse should clarify this prescription with the provider before implementing it. D. Incorrect. Maintaining the affected ankle elevated and immobilized can help prevent further injury and promote healing, but it does not require clarification with the provider.
