Question

A nurse is preparing to mix NPH insulin and insulin aspart in a single syringe for a client who has type 2 diabetes mellitus. Identify the sequence the nurse should follow.

A) Inject air into the vial equal to amount of insulin aspart prescribed.
B) Withdraw the prescribed volume of insulin aspart into the syringe.
C) Inject air into the vial equal to the amount of NPH insulin prescribed.
D) Withdraw the prescribed volume of NPH insulin into the syringe.

Answer 1

To mix NPH insulin and insulin aspart in one syringe for a type 2 diabetes patient, inject air into the NPH insulin vial, then into the insulin aspart vial before withdrawing the insulin aspart and then the NPH insulin. This sequence ensures no contamination of the rapid-acting insulin with the intermediate-acting insulin, which is essential for proper diabetes management.

Step-by-step explanation:

When a nurse is preparing to mix NPH insulin and insulin aspart for a client with type 2 diabetes mellitus, the correct sequence follows a specific procedure to ensure safety and efficacy. The steps for drawing up insulin are as follows:

1. Inject air into the NPH insulin vial equal to the amount of NPH insulin prescribed.
2. Withdraw the needle without drawing up the NPH insulin.
3. Inject air into the insulin aspart vial equal to the amount of insulin aspart prescribed.
4. Withdraw the prescribed volume of insulin aspart into the syringe.
5. Reinsert the needle into the NPH insulin vial.
6. Turn the vial upside down and withdraw the prescribed volume of NPH insulin.

This sequence ensures that the short-acting or rapid-acting insulin (insulin aspart) is drawn up first, preventing contamination of the short-acting insulin with the intermediate-acting insulin (NPH). Understanding this procedure is critical in managing blood glucose levels for individuals with diabetes mellitus, utilizing proper techniques for insulin injections.
