What are symptoms of type 2 diabetes? - ANSWER-polyuria, polydypsia, polyphagia, weight loss, blurred
vision, yeast infections
What does metformin do? - ANSWER-Decreases the amount of glucose produced by the liver, increases
the body response to insulin
What are contraindications for metformin use? - ANSWER-Kidney impairment
What is the prime drug for mono therapy when treating diabetes? - ANSWER-Metformin
,What is the plan of action when it comes to metformin and contrast interaction? - ANSWER-Metformin
should be temp. D/C prior to the procedure at least 48 hrs and then shouldn't be restarted until renal
function is checked and confirmed to be okay
What do sulfonylureas drugs do? - ANSWER-Stimulate insulin release from the beta cells
What are some sulfonylureas drugs used to maintain diabetes? - ANSWER-Glipizide, Glyburide,
Glimepiride
What do Thiazolidinedione drugs do? - ANSWER-decrease liver glucose production, increase sensitivity
to insulin
what are contraindications of Thiazolidinedione drugs? - ANSWER-Heart failure
Special considerations for when someone is taking Thiazolidinedione drugs? - ANSWER-can cause liver
disturbances, so pts have to get liver panels checked every 3 months
What do GLP-1 agonist drugs do? - ANSWER-they work at the level of the beta cells, are agonists for a
protein that increases secretion of insulin
What are some rapid acting insulins? - ANSWER-ASPART, lispro, glulisine
what are some intermediate acting insulins? - ANSWER-NPH, 70/30, 50/50, 75/25
When should rapid acting insulins such as lispro be given? - ANSWER-should be given within 10 min of
meal time
When do rapid acting insulin such as lispro peak, and when is it gone - ANSWER-Peaks within 1 hr of
administration, gone between 3 and 5 hrs
when do intermediate insulins such as NPH peak and end? - ANSWER-Peak within 4-12 hrs after admin
, When do short acting insulins such as regular insulin peak? - ANSWER-Peak within 2-4 hrs after
administration
when do long lasting insulin such glargine(Lantus) and insulin detemir(Levemir) peak? - ANSWER-
Glargine has no peak, detemir peaks between 6-8 hrs and has a duration of 5-24 hrs
What are the steps for mixing insulins? - ANSWER-1.Air into cloudy
2.Air into clear
3.Draw up clear
4.Draw up cloudy
Considerations for insulin injections - ANSWER-Preferred injection site is on the abdomen 2 inches away
from the umbilicus, make sure to rotate sites, do not massage injection sites
What are normal Sugar levels - ANSWER-70-120
Under what sugar level do hypoglycemia symptoms occur? - ANSWER-Under 50
How does alcohol effect sugar levels? - ANSWER-Prevents the liver from generating glucose, so sugar
drops
What is the dawn phenomenon? - ANSWER-Overnight release of growth hormone that causes a release
of glucose between 5am-6am, causes AM hyperglycemia, manage by increasing overnight insulin
dose(intermediate to long acting)
What is Somogyi phenomenon? - ANSWER-rebound hyperglycemia response from overnight
hypoglycemia, treatment is aimed at preventing overnight hypoglycemia, advise that the client eat a
snack, decrease insulin dosage
what is diabetic foot - ANSWER-A common foot injury complication, damaged nerve fibers cause pain
and decreased sensation or numbness, decreased blood supply makes cuts and sores harder to heal,
may lead to amputation
