Summary
This podcast episode gives nurses a practical, bedside-focused guide to insulin therapy, helping simplify one of the most important—and often confusing—areas of diabetes management. It reviews key insulin types, including rapid-acting insulin lispro, long-acting insulin glargine, and intermediate options like NPH insulin, highlighting onset, peak, and duration differences that drive dosing decisions. Nurses will learn how to safely administer insulin, adjust for meals and blood glucose trends, and recognize and treat hypoglycemia quickly. Real-world clinical tips are included to help nurses feel confident managing insulin in both inpatient and outpatient settings.

| 0:00.0 | In this section, I want to talk about insulin therapy. |
| 0:03.7 | First and foremost, let's talk a little bit about insulin administration. |
| 0:07.7 | So here I'm really focusing on subcue type of injections. |
| 0:13.0 | So those injection sites, abdomen is pretty much what everybody is going to use. |
| 0:19.1 | But in rare cases where that you know may not be an |
| 0:23.1 | option for some reason or something we do have other potential options but again everybody's |
