The nurse is teaching a child with type I diabetes mellitus to administer insulin. The child is receiving a combination of short-acting and long-acting insulin. The nurse knows that the child has appropriately learned the technique when the child:

The correct answer is B: Draws up the short-acting insulin into the syringe first. This is because when administering a combination of short-acting and long-acting insulin, it is crucial to draw up the short-acting insulin first to prevent contamination or mixing of the two insulins. Short-acting insulin should be clear and colorless, while long-acting insulin is cloudy. Drawing up the short-acting insulin first ensures accurate dosing and prevents altering the long-acting insulin's effectiveness. Administering the insulin IM into rotating sites (A) is incorrect as insulin is typically administered subcutaneously. Wiping off the needle with an alcohol swab (C) is a good practice for hygiene but does not affect the order of drawing up insulin. Administering the insulin into a doll at a 30-degree angle (D) is irrelevant and not a recommended technique for insulin administration.
