When teaching a school-age child and the parent how to administer insulin, which of the following instructions should the nurse include?
Correct Answer: C
Rationale: It is essential to give insulin at room temperature to prevent discomfort during administration. Cold insulin can cause stinging and pain, which can be avoided by allowing the insulin to reach room temperature before administration. Storing insulin in the refrigerator is correct for long-term storage, but it should be brought to room temperature before use. Rotating injection sites is important to prevent lipohypertrophy, a condition characterized by fatty lumps that can develop if injections are consistently given in the same area. Administering insulin within 30 minutes of a meal is generally recommended to match the insulin peak action with the peak glucose levels after eating, but giving insulin at room temperature is more crucial to ensure comfort and proper absorption.
