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

Diabetes Mellitus
Normal Blood Glucose99 mg/dl – upper level of normalHemoglobin A1c
Type II MedicationsStimulates the pancreas to release more insulin and to
increase sensitivity of body cells to insulinGiven twice daily, before meals
Glyburide (Diabeta) Glucophage (Metformin) Rosiglitazone (Avandia)

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

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

Blood Glucose Monitoring
Done 2-4 times per day if on subq insulin

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