Final answer:
Rapid-acting insulin, such as insulin lispro and insulin aspart, act quickly to lower blood sugar levels. They are often used before or after meals. Nursing considerations include checking blood sugar levels and monitoring for hypoglycemia.
Step-by-step explanation:
Rapid-acting insulin, such as insulin lispro and insulin aspart, act quickly after injection to lower blood sugar levels. These insulins start working within 15 minutes, peak in about 1 hour, and last for 2-4 hours. They are often used before or after meals to control postprandial (after-meal) blood sugar spikes. Some nursing considerations for administering rapid-acting insulin include checking blood sugar levels before and after administration and monitoring for signs of hypoglycemia.
