Term | Definition |
Insulin Regimens for type 1 DM: types of insulin | Rapid, short, intermediate & long-acting
-Given 1 or more x a day based on glucose results |
Other ways to administer insulin? | Pump (con't), pens |
Rapid acting insulin: (Pg. 915) | Lispro insulin (Humalog), Aspart insulin (Novolog), Glulisine insulin (Apidra)
-Administer before meals
-Onset is rapid: 10-30 mins (<15)
-Administer in conjunction w intermediate or long-acting insulins = glycemic control between meals & at nights |
Short acting insulin: | Regular insulin (Humulin R, Novolin R)
-Administer 30-60 min before meals |
Short-acting insulin is available in 2 concentrations:
U-500
U-100 | U-500; for complete insulin resistance, NEVER administered IV
U-100; for most clients; can be given IV |
Intermediate-acting Insulin: | NPH insulin (Humulin N), detemir insulin (Levemir)
-For glycemic control between meals & at nights
NOT administered before meals |
Intermediate-acting insulin contains ____ ? | Protamine (a protein), causes a delay in the insulin absorption or onset and extends the duration of action of the insulin |
How is NPH insulin administered? | SUB Q |
What is the only insulin that can mix w short-acting insulin? | NPH insulin (Humulin N) .. immediate-acting insulin |
How is determir insulin (Levemir) administered? | SUB Q |
Can you mix determir insulin (Levemir) with other insulin? | No |
Long-acting insulin: | Glargine insulin (Lantus)
Peak-less, trough-less
Administered once daily, anytime during the day but always at same time |
How does Lantus work? | Microprecipitates; dissolves slowly over 24 hours & maintains a steady blood sugar level |
How is lantus administered? | SUB q, never IV |
At what angle do you inject insulin? | 90 degree; 45 if thin |
When mixing a rapid or short-acting insulin w a longer-acting insulin which one do you draw up first? | Draw up the shorter-acting insulin first (regular) & then the longer-acting insulin
-reduces risk of introducing the longer acting insulin into the short-acting vial |
S/S of hypoglycemia: | Mild shakiness, mental confusion, sweating, palpitations, headache, lack of coordination, blurred vision, seizures & coma |
How can you avoid hypoglycemia: | Avoid excess insulin, extreme exercise, alcohol on an empty stomach |
Hypoglycemia level? | 70 or less |
What should we give a hypoglycemic client? | 15-20g of a readily absorbable carb (4-6oz of fruit juice or regular soft drink, 3-4 glucose tablets, 8-10 hard candies, or 1 tbsp of honey)
-recheck glucose in 15 min |
If carbs are given and still not in NL? | Give 15-20 more and recheck in 15 |
How much does BG increase over 30 mins following ingestion of 10g of carbs? | 40mg/dl |
What if hypoglycemic patient is unconscious or unable to swallow? | Administer glucagon subq or IM (repeat if 10 minutes) & notify provider
-In acute care, nurse gives IV 50% dextrose, conscious in 20 |
S/S of hyperglycemia? | Hot, dry skin, fruity breath |
If pt is hyperglycemic?
fluids, insulin, BG, urine | oral fluid/nonsugary prevent dehydration, administer insulin, restrict exercise w BG >250, test urine for ketones |
Oral hypoglycemics:
1. Metformin HCI (Glucophage)
action- | Reduces production of glucose by the liver (gluconeogenesis)
-Increases tissue sensitivity of insulin |
S/e of metformin? | (Glucophage)
-GI effects (gas, anorexia, nausea/vomit), lactic acidosis
* stop med for 48hr before radio test w iodinated contrast dye |
Education on metformin?
food? supplements? pregnancy? crush or chew? | Take w food, take vit b & folic acid supplements
can take during pregnancy
never crush or chew med |
What are..
Glipizide (Glucotrol), Glimepiride (Amaryl), Glyburide (Diabeta, glynase prestab) | Second-generation sulfonlyureas
-Stimulate insulin release from the pancreas = decrease in BG levels
-increase tissue sensitivity to insulin |
S/e of second generation sulfonylureas (oral anti diabetics) | Monitor for hypoglycemia |
Education for second generation? | Administer 30 mins before a meal
-avoid alcohol |
What is lipohypertrophy? and lipoatrophy? and how can you prevent it? | Increased swelling of fat
Loss of fat tissue
-Rotate injection sites within one anatomic site; prevents day to day changes in absorption rate |
Foot care:
-wash feet how often and with what?
-how do you dry & what to avoid | Daily w mild soap & warm water (test w hands)
-Pat dry, especially in-between the toes, avoid lotions between toes |
What should you use on sweaty feet?

w cotton & lamb wool |
Avoid what kind of shoes? | Open-toe, open-heal, slippers w/o souls, plastic shoes
NO barefoot |
What kind of stockings?
Heating pads okay? | Clean, absorbent stockings, cotton/wool (better absorption)
