Step-by-step explanation:
The nurse should tell the AP to complete the task of performing blood glucose monitoring of a client who has a prescription for short-acting insulin prior to breakfast first. This task is important because it is time-sensitive and must be done before the client consumes any food. Monitoring blood glucose levels is essential for clients with diabetes who require insulin injections to manage their blood glucose levels. By completing this task first, the AP can ensure that the client receives the necessary medication and their blood glucose levels are properly monitored.
