A nurse is preparing an in-service presentation about the use of automated external defibrillators (AEDs). Which of the following instructions should the nurse include in the teaching?

A. Use a cotton-tip applicator to relieve itching inside the cast.: Inserting any object into the cast can damage the underlying skin, cause abrasions, or introduce infection. Scratching inside the cast may also compromise cast integrity.

B. Report any drainage from the casted leg.: Drainage can indicate bleeding, wound infection, or impaired circulation under the cast, all of which require prompt evaluation. Early reporting helps prevent complications such as compartment syndrome or infection progression.

C. Keep the casted leg flat for the first 24 hr.: Elevation, not a flat position, is recommended in the first 24 to 48 hours to minimize swelling and pain. Keeping the leg flat can increase edema, which may impair circulation and delay healing.

D. Apply a heating pad to the casted leg.: External heat should be avoided because it can cause burns under the cast where the skin cannot be directly monitored. Heat also increases blood flow and swelling, which can worsen pain and increase pressure within the cast.

A. "I will take my insulin 30 minutes before exercise.": Administering insulin immediately before exercise increases the risk of hypoglycemia. Timing of insulin should be coordinated with meals and activity, and clients should monitor blood glucose closely before and after exercise.

B. "I will limit my fluid intake to 1 liter daily.": Restricting fluids is not recommended for clients with diabetes, as adequate hydration helps prevent hyperglycemia and supports kidney function. Limiting fluids could increase the risk of dehydration and complicate blood glucose control.

C. "I will eat a low-residue diet.": A low-residue diet is typically used for gastrointestinal disorders, not diabetes management. Clients with diabetes benefit from a balanced diet that includes fiber to help regulate blood glucose and promote overall health.

D. "I will use a mirror to inspect my feet daily.": Daily foot inspection is an important self-care practice for clients with diabetes to identify early signs of injury, infection, or neuropathy. Using a mirror helps the client see areas that are difficult to view, supporting prevention of complications such as ulcers.
