A client with diabetes mellitus must learn how to self-administer insulin. The physician has prescribed 10 U of U- 100 regular insulin and 35 U of 100-U isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?

  • A. “Inject insulin into healthy tissue with large blood vessels and nerves.”
  • B. “Rotate injection sites within the same anatomic region, not among different regions.”
  • C. “Administer insulin into areas of scar tissue or hypotrophy whenever possible.”
  • D. “Administer insulin into sites above muscles that you plan to exercise heavily later that day.”
Correct Answer: B

Rationale: The correct answer is B: “Rotate injection sites within the same anatomic region, not among different regions.” This instruction is important to prevent lipodystrophy and ensure consistent insulin absorption. Rotating sites within the same region helps maintain consistent insulin absorption rates and reduces the risk of developing scar tissue or fatty deposits. Injecting into healthy tissue with large blood vessels and nerves (choice A) can lead to inconsistent absorption. Administering insulin into areas of scar tissue or hypotrophy (choice C) can also disrupt absorption. Injecting into sites above muscles planned for exercise (choice D) can lead to unpredictable insulin absorption. Rotation within the same region optimizes insulin delivery and prevents complications.
