Pharmacology for Nursing - Diabetic drugs Insulin Types & Memory Tricks (Peak, Onset, & Duration) RN
Summary
Highlights
This section introduces the core concepts of diabetic treatments, distinguishing between Type 1 (insulin-dependent) and Type 2 diabetes (lifestyle-related with insulin resistance). It outlines the foundational 'seven rules of insulin' that are crucial for NCLEX exams. Key takeaways include matching food intake with insulin peaks to prevent low blood sugar, identifying and treating hypoglycemia (sugar below 70), and knowing which insulin types are suitable for IV administration.
This part delves into long-acting insulins like Glargine and Detemir, noting their extended duration and lack of a peak, which minimizes hypoglycemia risk. A memory trick provided is 'glargine is large, detemir lasts all year.' It also covers NPH, an intermediate insulin, emphasizing that it's cloudy, always mixed, never given IV, and has a peak between 4-12 hours, with the most dangerous time being 5-6 hours post-administration.
Nurse Mike explains regular insulin, highlighting its unique role as the only insulin safe for IV administration (IV push or IV bag). Its peak is between 2-4 hours. The discussion then moves to rapid-acting insulins (Lispro, Aspart, Glulisine), which are the most critical due to their rapid onset (15 minutes) and peak (30-90 minutes). Memory tricks like 'Aspart, you gotta move your ass parts' and 'Lispro, less time' are used to remember their quick action. It's crucial to give these insulins when the patient is actively eating or food is bedside to prevent severe hypoglycemia.
This section tests understanding with NCLEX-style questions focusing on insulin peak times and appropriate actions. Examples include managing regular insulin when food isn't finished and advising a client on Aspart insulin to eat quickly. It reinforces the importance of memorizing peak times for different insulin types by referring to a study guide for daily review.
The video concludes by discussing insulin infusion pumps (Continuous Subcutaneous Insulin Infusion or CSI). The primary benefit is providing a steady insulin dose, reducing blood sugar fluctuations in Type 1 diabetics. Users typically check blood sugar four times daily and use a bolus button for meal times. A critical NCLEX point is to always assess the patient first, then the machine, in case of a pump malfunction.
