Final answer:
Lispro insulin should be administered by the nurse within 15 minutes before a meal or immediately after starting to eat to manage blood glucose levels effectively.
Step-by-step explanation:
Lispro insulin is a rapid-acting insulin analogue used to control blood glucose levels in individuals with diabetes. It works quickly to lower blood glucose levels and is typically administered immediately before meals to coincide with the blood glucose rise that occurs after eating. The nurse should give lispro insulin within 15 minutes before a meal or right after the patient starts eating to ensure that insulin is available when the glucose from the meal starts to enter the blood.
Injecting lispro insulin at the correct time is crucial because it peaks rapidly and helps prevent postprandial hyperglycemia, which is the spike in blood glucose levels after eating. Additionally, understanding insulin tolerance and the body's response to insulin can help in managing diabetes effectively.
Patients with insulin responsive diabetes mellitus (IDDM) will experience a decrease in blood glucose levels upon injection of insulin, as it aids in the uptake and utilization of glucose by the body's cells. However, in insulin non-responsive patients, there may be little to no change in blood glucose levels due to issues such as defective insulin receptors or the presence of insulin antibodies.
