A nurse is reinforcing teaching about self-administration of insulin with a parent of a school-age child who has a new diagnosis of diabetes mellitus. Which of the following statements by the parent indicates a need for further teaching?

Choice A reason: Aspiration before insulin injection is outdated and unnecessary, as modern subcutaneous injections into adipose tissue pose minimal risk of entering a vessel. This practice delays administration and increases discomfort. The parent’s statement reflects incorrect technique, indicating a need for further teaching to ensure safe insulin delivery in diabetes management. Choice B reason: Insulin injections into adipose tissue (e.g., abdomen, thigh) ensure proper subcutaneous absorption, minimizing intramuscular injection risk. This statement is correct, as insulin is effectively absorbed in areas with sufficient fat, supporting glycemic control. The parent’s understanding aligns with standard practice, requiring no further teaching on injection site selection. Choice C reason: A 90-degree angle is appropriate for subcutaneous insulin injections in children with adequate adipose tissue, ensuring proper drug delivery. This statement is correct, reflecting proper technique for insulin administration to achieve consistent absorption and glycemic control, indicating the parent understands this aspect of diabetes management. Choice D reason: Rotating injection sites after two injections prevents lipodystrophy, ensuring consistent insulin absorption. This statement is correct, as site rotation minimizes tissue damage and maintains efficacy in diabetes management. The parent’s understanding is accurate, requiring no further teaching on this critical aspect of insulin administration technique.
