10
Q
Insulin functions
A
- carries glucose into body cells as their preferred source of energy
- promotes the livers storage of glucose as glycogen
- inhibits the breakdown of glycogen back into glucose

Q
Polyuria
A
excessive urine

19
Q
Diabetic BS check
A
- glucometer
- upper arm,forearm,calf,thigh
- fingertips preferred
20
Q
Normal A1c

below 7%
21
Q
Lagging site
A
- alternate sites to check glucose
- tells blood sugar 20 to 30 minutes prior
- upper arm,forearm,thigh, calf
22
Q
Most accurate glucometer reading
A
fingertip
23
Q
Meal plans for diabetes
A
- carb counting (15 g per meal)
- calorie counting (1500 per day)
24
Q
How much should a diabetic exercise?
A
- 150 minutes a week
- 3 days a week
- dont skip more than 2 days in a row
- exercise allows you to burn glucose
25
Hyperglycemia treatment
- insulin

Jet injector
given with air not needle
29
Insulin pump
continuous infusion
30

39
Ketoacidosis treatment
- insulin given through IV
- replace potassium/electrolytes
- monitor electrolytes and blood glucose
- urine is tested for glucose and ketones
40
What causes fruity breath odor?
ketoacidosis
