Q

Insulin strength

A

Most patients use U-100 (U-40 and U-500 are available). The numeral following the “U” indicates the number of units of insulin per milliliter

Q

Source of Insulin

A

All insulins currently on market are “semi-synthetic” or “human” insulin (using recombinant DNA technology ) Some products are referred to as human insulin identical to insulin produced in pancreas (Humulin R, Humulin N, Humulin 70/30); Other products, referred to as human insulin analogs, are modified forms of human insulin (Humalog, insulin lispro):

immediate effects so blood glucose will drop fast so pt need to eat. don’t want pt blood glucose to bottom out

23
Q

Humulin N (Neutral Protamine Hagedorn) prepared

A

by conjugating regular insulin with protamine; the protamine decreases the solubility of NPH insulin and prolongs absorption (intermediate acting)

24
Q

Humulin N (Neutral Protamine Hagedorn) onset of action

A

is delayed and duration of action extended

25
Q

Humulin N (Neutral Protamine Hagedorn) given

A

twice daily to provide glycemic control between meals and during night

26
Q

Humulin N (Neutral Protamine Hagedorn) can be mixed with

A

with regular insulin (draw up regular first in syringe)

27
Q

Humulin N (Neutral Protamine Hagedorn) onset

A

60-120 min. Peaks: 6-14 hrs. Lasts 16-24 hrs

28
Q

Humulin N (Neutral Protamine Hagedorn) supplied

A

as a cloudy suspension

29
Q

if mixing humulin N with regular then draw up

A

regular (clear) insulin first then humlin N (cloudy)

30
Q

Lantus (insulin glargine)

A

long acting

31
Q

Lantus (insulin glargine) ia a

A

modified human insulin with a prolonged duration of action (at least 24 hours)

32
Q

Lantus (insulin glargine) given

A

once-daily subQ, recommended at night

33
Q

Lantus (insulin glargine) allows for

A

Allows for once-daily dosing; most like patient’s basal insulin release Lantus

34
Q

after injection of Lantus (insulin glargine) the

A

the acidic solution is neutralized, leading to formation of microprecipitates from which small amounts of insulin are slowly released; • Result is a relatively constant concentration over 24 hours with no pronounced peak

35
Q

Can you mix other types of insulin with Lantus?

A

no

36
Q

Does Lantus “look” funny?

A

YES, compared to NPH, it’s clear

37
Q

pt on lantus would also most likely been on what for meal time

A

rapid acting insulin

38
Q

when administering insulin you should know

A

your onset, peak, & duration times

39
Q

pts must _______ when receiving insulin

A

EAT

40
Q

Consider holding or lowering insulin dose if patient

A

is NPO…Consult physician

41
Q

when administering insulin look for

A

signs & symptoms of hypoglycemia

42
Q

signs & symptoms of hypoglycemia **

A

headache, light headedness; nervousness, apprehension, tremors; excess perspiration, cold, clammy skin; tachycardia, slurred speech, confusion

43
Q

signs of hypoglycemia appear when blood sugar level

A

is < 60 mg/dl (the more it drops the more pronounced the symptoms are

44
Q

pts must _______ when receiving insulin

A

EAT

45

46

47
Q

signs & symptoms of hypoglycemia **

A

headache, light headedness; nervousness, apprehension, tremors; excess perspiration, cold, clammy skin; tachycardia, slurred speech, confusion

48
Q

signs of hypoglycemia appear when blood sugar level

A

is < 60 mg/dl (the more it drops the more pronounced the symptoms are

49
Q

insulin keep at

A

room temperature but only for 1 month after opening (date). Keep Unopened bottles in refrigerator

50
Q

for injections absorption is

A

fastest in abdomen, then deltoid, thigh, and buttocks

51
Q

for injections rotating sites prevent

A

lipohypertrophy (increased swelling of fat tissue in skin) and lipoatrophy (loss of fatty tissue); • Rotation WITHIN on anatomic site is preferred

52
Q

The equivalency of 10-15 grams of glucose (approximate servings) are:

A

Four lifesavers ; 4 teaspoons of sugar ; 1/2 can of regular soda or juice (can be used for Treatment of Hypoglycemia)

53
Q

Once the acute episode of hypoglycemia has been treated,

A

a healthy, long-acting carbohydrate to maintain blood sugars in the appropriate range should be consumed. Half a sandwich is a reasonable option

54
Q

What if pt is hypoglycemic and is comatose & cannot take anything by mouth?

A

then use glucagon

55
Q

glucagon

A

causes a rapid release of glucose stores from the liver. It is an injection given intramuscularly to a patient who cannot take glucose by mouth. A response is usually seen in minutes and lasts for about 90 minutes.

56
Q

If glucagon is not available and the patient is not able to take anything by mouth,

A

emergency services (for example 911) should be called immediately. An intravenous route of glucose (Dextrose 50%) should be administered immediately.
