Q

How should you store insulin

A

Open vials at room temp, discard opened vials after recommended interval

Durable pens and dosing devices: do NOT refrigerate after open

Q

In T2DM, if A1c is not met and blood sugar is still rising, consider

A

Dosing insulin for basal and bolus coverage

start bolus with 1, 2, or 3 meals a day

Q

Where should all insulin injections be taken

A

in the abdomen- most consistent absorption

If unwilling to follow, do systemic site rotation BUT- always give insulin injection in same region at same time of day

Q

What is TDD (total daily dose)

A

A way to calculate the total amount of insulin a patient needs per day

  1. 4 units/kg in normal patients
  2. 5 units/kg in overweight
    alternate: weight in lbs/4

16
Q

What is “background” or “basal” insulin replacement

A

replacing insulin overnight when you are fasting between meals (40-50% of TDD)

17
Q

What is the “bolus insulin replacement”

A

The remaining 50-60% of TDD of insulin should be given to cover carbs and high blood sugar correction

18
Q

What is ideal basal:bolus ration

A

50:50
If it is not close to this, reassess
*Basal is further broken down into biggest dose (20%) at Bfast, then 15% at lunch and dinner

19
Q

How can you instruct a patient to titrate insulin

A

increase LONG acting 1 unit each day until FBS is 80-120
OR
increase LONG acting 1 unit q2-3 days until FBS is 80-120

20
Q

How can you tell a patient to relieve Sx of hypoglycemia

A

Eat 15 g of glucose (carbs)
Recheck your BG after 15 minutes
If still hypoglycemia, repeat until your BG normalizes
-If your next meal is >2 hrs away, eat a small snack after your blood glucose is normalized

21
Q

What are examples of “15g” of carbs

A
glucose tablets, gel tube 
2 tbsp raisins 
4 oz (1/2 cup) of juice/regular soda (not diet) 
1 tbsp sugar, honey, or corn syrup 
8oz nonfat or 1% milk 
hard candies, jelly beans, gumdrops
22
Q

What are good resources for diet planning

A

ChooseMyPlate.gov

Carb Counting book

23
Q

What should bolus insulin be based on

A

amount of carbs to be consumed

-Pts can self adjust their dose of bolus insulin based on what they’ll be eating (insulin:carb ratio)

24
Q

Per her ppt (not her PEARLS), how do we calculate how many carbs insulin covers

A

500/TDD
If TDD is 76 units insulin, 500/76= 7g
1 unit insulin covers 7g carbs (but you should round to like 10)
Insulin:Carb= 1:10

25
What is Correction Factor
The glucose lowering effect of 1 unit of rapid acting insulin 1700/TDD so if TDD is 76 units, 1700/76= 22, round to 25 Each unit of insulin will lower BG 25mg (for short acting insulin use 1500)
26
What is the "rule of 1800"
The "insulin sensitivity factor" which basically uses 1800 as the correction factor number instead of 1500 or 1700??
27
How do you calculate correction dose
Actual BG before meal (-) target BG (/) correction factor | Ex: 220 - 110 / 25 = appx 4 units
28
How do you calculate total mealtime dose
CHO insulin dose (rule of 500) + high BG correction dose= total meal insulin dose 7 units + 4 units= 11 units of insulin should be given for this meal
29
How should you instruct a patient to take NPH and Rapid acting dosing
Calculate TDD- give 2/3 in the morning (2/3 NPH, remainder R) and the 1/3 in the evening (2/3 NPH, remainder R) Give 30 min before eating
30
When making adjustments, which lab values do you fix first
Fix FBS first, then fix post prandial blood sugar | because, FBG represents the insulin given the night before!
31
What is sliding scale insulin
You adjust the dose of insulin based on the normal amount of CHO the patient eats
32
What is a relative contraindication to insulin therapy
Hypoglycemic unawareness- autonomic neuropathy or frequent episodes of hypoglycemia make it hard for the pt to recognize he is hypoglycemic
33
What is asymptomatic erratic gastric emptying
a d/o that severely hinders the ability to match insulin to meals- must do gastric emptying study
34
What effect does exercise have on BG
it can continue to lower BG for 6-8 hrs | so, tell pt to work out at a consistent time each day and avoid late night exercise until insulin doses are stable
35
How does a patient adjust when they are sick
Kcal intake usually decreases, as well as insulin sensitivity= It takes more insulin to control BG Try to maintain 120-150g CHO per day, and SBGM more frequently Also test for ketones!
36
What happens to insulin therapy after an islet cell or whole pancreas transplant
They usually can stop insulin | But, w/in 2 years of transplant they usually start some form of insulin therapy again
