Which pharmacokinetic variables are important for a nurse to teach a client about insulin?

The important pharmacokinetic variables for a nurse to teach a client about insulin are peak, duration, and onset. Understanding these three elements is crucial for effective insulin management.

Onset refers to the time it takes for insulin to start lowering blood glucose levels after it has been administered. This knowledge helps clients to time their food intake appropriately to avoid hyperglycemia or hypoglycemia.

Peak indicates the time at which insulin reaches its maximum effect, which is vital for understanding when the risk of hypoglycemia is the greatest. Clients need to know when to monitor their blood glucose closely, especially if they are administering rapid-acting or short-acting insulins.

Duration refers to how long the insulin's effects last in the body. This informs clients about how long they can expect the insulin to work and helps them determine the timing of their next dose or food intake.

Together, these factors provide critical information that influences how and when clients manage their diabetes, ensuring they achieve optimal glycemic control and avoid potential complications.
