Q

General insulin dosing principles

A

-inc/dec dose q2-4 days
-target FBS (A1c >10)first then PPG (A1c<10)
-pt can be taught how to adjust their own dose for exercise/meals

21
Q

Adjusting / Indivdualizing insulin doses

A

-carbohydrate ratio
-sensitivity factor
-overall principles

22
Q

Insulin to carb ratio

A

-guide for how much insulin one needs to cover an amount of carb in a meal or snack

23
Q

Average insulin to carb ratio

A

-1unit: 10-15g carbs adults
-1unit: 20-30g carbs children

24
Q

calculating insulin:carb ratio

A

-total carbs/day for 3-day
-establish avg carb intake amount per meal
-g of carbs/amt of bolus given
-60g/6unit= 1:10 ratio
-check blood sugar pre/post meal to determine effectiveness
-rule of 500

25
Q

rule of 500 to calc insulin:carb

A

-500/TDD = g/1unit
-500/40 units = 1:12.5g
-for 60g = 5 units insulin to cover meal

26
Q

more than one insulin:carb ration might be needed

A

-physical activity
-body weight
-insulin needs
-type of meal

27
Q

Insulin sensitivity factor (correction factor) CF or ISF

A

-rule of 1800 (1500 in case they on regular insulin)
-1800/TDD
-estimates how much 1 unit will lower blood glucose
-1800/90units = 20mg/dL lowered by 1 unit
-used most to add to a dose of prandial insulin when BG elevated
-caution just using to correct hyperglycemia often

28
Q

CF/ISF

A

=x:50>150

-add x units for every 50 over 150 (BG)
-x from rule of 1800
-50/20 = 2 units
-2 units for every 50mg/dL above 150

-if u give an hs dose, maybe half it

29
Q

Fasting hyperglycemia causes

A

-bedtime eating
-not enough insulin
-Somogyl effect

30
Q

Fasting hyperglycemia tx

A

-if once daily basal, inc dose or change to BID
-if BID, inc supper/bedtime dose
-if basal-bolus, inc basal or PM bolus depending on hs readings

31
Q

Prelunch hyper glycemia tx

A

-add/inc shortacting to am dose

32
Q

predinner hyperglycemia tx

A

-inc am basal or add short acting at lunch
-inc short-acting dose if applicable

33
Q

bedtime hyperglycemia tx

A

-add/inc dose short acting at dinner

34
Q

Fasting hypoglycemia tx

A

-dec evening insulin dose
-check timing of AM test and dose

35
Q

Pre lunch hypoglycemia tx

A

-dec/omit shortacting dose in AM

36
Q

Pre-dinner

A

-dec lunch bolus
-dec AM basal

37
Q

Bedtime hypoglycemia

Q

how to adjust insulin

A
