When administering glargine, the nurse will explain that there is no peak time for this insulin. Glargine is a long-acting insulin that provides a steady level in the bloodstream, helping to keep blood sugar levels stable over a 24-hour period without the peaks and valleys that can occur with other insulin types. This means that glargine works continuously in the background, making it a fantastic option for maintaining basal insulin levels. It's important for the client to understand that while glargine controls blood sugar throughout the day and night, it doesn’t provide the rapid response needed for managing meals—thus they may still require mealtime insulin.
