Determining Site & Needle Size Amount & Characteristic of Medication Amount & Condition of Muscle Mass Frequency of Injection Type of Medication Age Recommended Route

Comfortable Injections Appropriate Needle Position of Client Relax muscle Proper Injection Site Rotate sites Insert Needle Quickly Hold syringe steady Diversion Z-Track

IM Injection: Z Track Pull skin laterally Hold taut w/nondominant hand Release skin after needle removed Less pain and more effective delivery

Complications of IM Injections Infection Lipodystrophy Nerve Damage Ecchymosis

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

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)

Insulin: Subcutaneous (35-10, p.743 P&P) Rapid-acting (lispro, aspart- Novolog) Short-acting (Regular) (CLEAR) Intermediate-acting (NPH) (CLOUDY) Long-acting Glargine (Lantus)*

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

Drawing Up 2 Insulins

Blood Glucose Monitoring 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

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