28. Diabetes Mellitus: Patho • Insulin is secreted by the Islets of Langerhans (Beta Cells) • Insulin lowers blood glucose levels after meals • Insulin moves glucose from the blood into the muscle, fat, liver, and cells • Types • I-IDDM • II-NIDDM

29. Diabetes Mellitus • Normal Blood Glucose • 99 mg/dl – upper level of normal • Hemoglobin A1c • Type II Medications • Stimulates the pancreas to release more insulin and to increase sensitivity of body cells to insulin • Given twice daily, before meals • Glyburide (Diabeta) • Glucophage (Metformin) • Rosiglitazone (Avandia)

31. Insulin: Nursing Implications • Monitor & assess for hypoglycemia • Anxiety/restlessness • Tremors • Diaphoretic • Cool/pale • Altered LOC • Confusion…lethargy…unconscious • Glucagon • 1mg dose-may repeat in 15” • Give subq or IM if unresponsive

32. Insulin: Subcutaneous • Given 1-4 times daily • Room Temperature for 30 Minutes • Gently roll, look for flocculation • Must use syringe that matches the insulin (U-100) • Verify dosages with another Nurse • If mixing do not keep in syringe longer than 15 minutes

33. Drawing Up 2 Insulins

34. Done 2-4 times per day if on subq insulin Done 3-4 times per week if on oral hypoglycemic (Oral Diabetic) therapy Sliding Scale Blood Glucose Monitoring

35. Heparin • Mechanism of action • Low dose • Prevents conversion of prothrombin to thrombin • High dose • Prevents conversion of fibrinogen to fibrin
