A nurse is preparing to mix short-acting and intermediate-acting insulin in one syringe to administer to a client who has type 1 diabetes mellitus. Identify the sequence the nurse should follow. (Move the steps into the box on the right, placing them in the selected order of performance. Use all the steps.)
Explanation & Rationale
A. Draw up a volume of air equal to the volume of insulin from the intermediate-acting insulin vial. Air is first drawn into the syringe for the intermediate-acting insulin to prevent creating a vacuum when withdrawing it later. C. Inject the volume of air equal to the insulin dose from the short-acting insulin vial. Injecting air into the short-acting vial prevents vacuum formation and makes withdrawal easier. D. Withdraw the prescribed amount of insulin from the short-acting insulin vial. The short-acting insulin is withdrawn first to avoid contaminating it with intermediate-acting insulin. B. Inject the volume of air equal to the amount of insulin to withdraw from the intermediate-acting insulin vial. Air is injected into the intermediate-acting vial before withdrawal to facilitate drawing up the insulin. E. Withdraw the prescribed amount of insulin from the intermediate-acting insulin vial. Finally, the intermediate-acting insulin is withdrawn, completing the mixture in the syringe.
