- The client/caregiver can state the action of insulin.
- Helps to control blood sugar levels in clients with type 1 diabetes mellitus.
- It is administered by insulin subcutaneous injection or insulin pump.
- Types of insulin are
- Humalog, Novolog (very short acting). The onset of action is 5 to 15 minutes, and the peak effect is after 30 to 60 minutes.
- Regular (short-acting). The onset of action is 30 minutes. The peak effect is after 2 to 5 hours.
- NPH (intermediate-acting). The onset of action is in 1 to 2.5 hours. The peak effect is after 8 to 14 hours.
- Lente (intermediate-acting). The onset of action is 1 to 2.5 hours. The peak effect is after 8 to 12 hours.
- Ultra Lente (long-acting). The onset of action is 4 to 6 hours. The peak effect is after 10 to 18 hours.
- Premixed combinations have the onset of action in 30 minutes. The peak effect is after 7 to 12 hours. Examples of combinations are 70/30 (70 intermediate/30 rapid-acting), 50/50 (50 intermediate/50 rapid-acting), and 75/25 (75 intermediate/25 rapid-acting).
- Lantus (insulin glargine). It has a constant long duration with no defined peak of action. It is usually given once a day and usually at bedtime.
- The client/caregiver can list possible adverse reactions to insulin.
- Hypoglycemia or low blood sugar
- Headache
- Sweating
- Hunger
- Nervousness
- Weakness
- Restlessness or sweating during sleep
- Hyperglycemia or high blood sugar
- Flushed
- Dry skin
- Nausea
- Fatigue
- Headache
- Dizziness
- Allergic reaction (seek emergency treatment)
- Hypoglycemia or low blood sugar
- The client/caregiver can list precautions when storing, preparing, and administering insulin.
- Keep insulin vials that are currently in use at room temperature. When not needed, store in the refrigerator. Never freeze insulin.
- Take insulin exactly as prescribed, and never adjust the dose without orders from the physician.
- Do not interchange beef, pork, or human insulins.
- Lantus insulin should never be mixed with other insulins.
- Never use insulin that has changed color or consistency.
- Rotate sites to prevent skin complications using the abdomen, upper and outer thighs, upper arms, and buttocks.
- Administer insulin promptly (within 5 minutes) after mixing insulins.
- Use only insulin syringes to administer insulin.
- Press—do not massage the injection site after administration of insulin.
- Dispose of syringes in an impermeable container.
- The client/caregiver can list other precautions when taking insulin.
- Limit cigarette smoking because it decreases the amount of insulin absorbed when given subcutaneously.
- Avoid alcohol and aspirin, which may increase the effect of insulin.
- Never omit meals.
- Carry a snack (source of simple sugar) at all times in case of low blood sugar.
- Wear a medical identification bracelet.
- Monitor and record blood or urine glucose levels.
- Monitor factors that affect the amount of insulin required:
- Follow diet closely as instructed.
- Exercise daily in constant amounts.
- Use stress management techniques.
- Obtain prompt treatment for any infections.
- Test blood sugar more frequently if a change in diet, activity, stress, illness, or infection occurs, and notify the physician.
- Keep follow-up appointments with the physician and laboratory.
- Report any signs of hypoglycemia, that is, headache, sweating, hunger, nervousness, and weakness.
- Report any signs of hyperglycemia, that is, flushed, dry skin; nausea; fatigue; headache; and dizziness.
- The client/caregiver can list measures to safely use an insulin pump.
- The insulin pump is used for continuous (24-hour) insulin delivery.
- The insulin pump has a pump reservoir and a computer chip that allows the user to control the exact amount of insulin being delivered and is battery operated.
- They are approximately the size of a beeper. It is attached to a thin plastic tube that has a soft cannula or needle at the end to deliver insulin.
- The cannula (needle) is inserted under the skin, usually on the abdomen. It needs to be changed every 3 days.
- The tubing can be disconnected when showering or swimming.
- The client/caregiver can demonstrate syringe preparation.
- Wash hands thoroughly.
- Assemble equipment: syringe, insulin, alcohol swab.
- Check that you are using the appropriate type of insulin and that it has not expired.
- Verify that you are using the appropriate type of syringe (only insulin syringe).
- Roll the insulin bottle gently to mix it.
- Cleanse the top of the bottle with alcohol.
- Pull the plunger of the syringe back the number of units of insulin to be injected, not allowing the needle to touch anything.
- Insert the needle into the bottle and inject air.
- Invert the bottle and syringe, and slowly withdraw the prescribed amount of insulin, being sure that the needle is under the fluid level.
- Check the syringe for air bubbles, and remove them by tapping the syringe. Draw up more insulin, and discard excess if necessary for an accurate amount.
- The client/caregiver can demonstrate the procedure for insulin injection.
- Wash hands. Check the previous rotation site and select the new site.
- Prepare the injection site by swabbing the center of the area with alcohol and moving outward in a circular manner about 2 inches. Allow the area to air dry.
- Pinch the skin approximately 2 inches with thumb and forefinger at the injection site, not touching the area that was cleaned.
- Inject the needle into the skin using a quick, firm motion at a 45-degree (normal weight) or 90-degree angle (obese patient).
- Inject insulin slowly into the tissue. Remove the needle, and hold the swab over the site briefly.
- Place the manufacturer’s needle guard to cover the needle and dispose syringe/needle in a safety container.
- The client/caregiver can list sites of the body for insulin injections.
- Upper arms
- Abdomen
- Thighs
- Buttocks
