Diabetes Mellitus 2

Exogenous Insulin
______: must be injected- Required for type 1 diabetes; and may be needed for the patient with Type 2 diabetes who cannot control blood glucose by other means.
Human insulin
Types of Insulin: ________- genetically engineered to be like human insulin. Animal insulin is more expensive, and have parts that are not useful to humans. Most widely used type of insulin. Decreased likehood of allergic reaction.
Insulins differ
______ in regard to onset, peak action, and duration. Varies in each person, Poor kidney function will last longer and increases risk of hypoglycemia.
Different types
_______ of insulins may be used for combination therapy. -Rapid acting: Laspro (Humalog), Aspart (Novolog), Glalister (Aspida), Exubera. -Short acting: Regular. Intermediate acting: NHP or Lente. Long acting: Lantus (Glaritus) , Levimir (Delemir).
Administration of insulin
Cannot be taken orally. SQ injection for self-administration. IV administration: use regular. Lantus cannot be mixed with any other insulins. Insulin can be stored at room temperature for up to one month. Flocculation of insulin: NPH molecule remain in clumps...wont work if this occurs.
Basal Insulin
Insulin Management: ________- Baseline insulin required to maintain normal glucose volumes while fasting between meals.
Bolus insulin
_______ (meal _____): occurs with meals, insulin required to curve the raise in the blood glucose following a meal.
Conventional Therapy
______: attempt to mimic normal body regulation of insulin. NHP and Regular (R/P). insulin. -N/R one injection/day: usually 30 mins before someone eats breakfast- Regular effects breakfast, NPH effects lunch and Hyperglycemia around dinner.
Somogyi effect
-NPH given at dinner peaks in the middle of the night causing a increase in blood glucose. Body Counterregulatory hormones are released causing blood glucose to rise. Care provider may increase dinner NPH, causing more severe nocturnal hypoglycemia and possibly higher FBS.
Somogyi effect: Solution
_________- Test 2-3 am glucose. If low, then move NPH to at bedtime, so that peak of NPH is shifted to later in early morning.
Dawn Phenomenon
______: Release of growth hormone, cortisol, glucagon between 4am - 11am contribute to: an increase in blood glucose. NPH given at dinner time is waning in action, and therefore will not control rise in blood glucose.
Dawn phenomenon: Solution
______: Test blood glucose 02-03. If it is normal, and FBS is elevated, the rise in blood glucose is likely related to Dawn Phenonomenon. Solution is the same: move NPH to bedtime.
Dawn phenomenon: Solution
______: The action of the NPH insulin given at Dinner time poops out before morning--- There is no basal insulin left in the system, and the blood sugar naturally rises...______ move NHP to bedtime.
Conventional Therapy
-N/R twice a day: Same as 1 injections but dinner is covered along with fasting blood glucose.
Conventional Therapy
-N/R 3 injections/day: NPH and Regular, Regular, and NPH later in the evening.
______: MDI= multiple dose injections. Baseline insulin and at meal time insulin. Fasting insulin provides both basal and bolus coverage.The pump more closely stimulates the physiological fueling of the pancreas, increases flexibility in lifestyle.
N + Log
Humalog is right before a meal, after a meal, great for children and Elderly.
Carbohydrate Counting
Allows someone with diabetes to match insulin to food eaten, rather than eating to feed insulin.
_____: Starches- 15 g of ____ in one serving; Fruits/Juices- 15g of ____ in one half cup; Milk- 12 g of ____ in one serving; Honey, Table sugar, syrup and candy
Why use

Insulin Sensitivity Factor
______ (ISF): Also called correction factor: how much one unit of insulin will lower the blood glucose (different for each patient).
Bolus Insulin
_____: amount given pre-meal, depends on...glucose goal, premeal blood glucose, insulin sensitivity factor (ISF).
Insulin Therapy: Disadvantages
______: You gotta inject it- hurt (insulin doesn't hurt). Hypoglycemia- if insulin is not managed correctly. Lipodystrophy: stop injecting in those sites, it may go away isn't painful.
Where to inject
Insulin Therapy: ______- Most rapid to least rapid insulin absorption: Abdomen, arms, thighs, buttocks. In Lantus doesnt matter where you apply. Pattern rotation: rotate within injection sites, rather than rotating to a different area with each injection. May decrease variability in absorption from day to day.
