Insulin Flashcards
Type 2 diabetes
- Usually formed due to lifestyle habits
- onset peaks in 50’s but can occur at any age
- slow onset/asymptomatic
Insulin
A hormone secreted by the beta cells of the islets of Langerhans of the pancreas
- physiologic effect is to enhance body metabolism of glucose
- lowers blood glucose
Fasting Blood Glucose(FBS)
- 10-12 hours fasting
- normal 70-100 mg/dL
•Abnormal >100-126=impaired
> 126mg/dL =abnormal(diabetes)
Glyconsylated hemoglobin A1c(HbA1c)
- Normal= 4-6%
- Abnormal= >8% indicates poor diabetic control
- 9% and higher shows that the average glucose level has been around 200mg/dL
Insulin for type 1 and 2
Type one must have it by injection due to loss of function from beta cells
Type two “may” need it by injection of the body isn’t recognizing its own insulin properly
Rapid acting insulin
- given before meals
- onset:20-30 minutes
- Peak:30min-3hr
- Duration:3-5 hours
- novolog
- humalog
Short acting insulin
-(R) Regular insulin
•Onset:30min-1hr
•Peak:2-5 hrs
•Duration:5-12 hours
Novolin
Humulin
Intermediate Acting insulin
-Given to prolong action of insulin for longer coverage
- Onset:1-4 hours
- Peak:4-14 hours
- Duration:10-24 hours
Long acting insulin
-Given for long term effect, such as for 24 hour coverage
- Onset:1-4 hours
- Peak: Lantus has no peak, Levemir:6-8 hours
- Duration:24 hours
Read insulin labels correctly
- Humulin R=regular(short acting)
- Humulin N=NPH(Intermediate)
- Humulin 70/30= 70%N/30%R
Concentrations of insulin
•U-100 means there are 100 Units per 1mL(most common in US)
Insulin syringes
Two types of syringes 50 unit volume and 100
Insulin pen
- patients prefer pen
- Attach new needle each time and PRIME with two units of insulin
-give insulin in subcut routes
Storage of insulin
- May be stored at room temp for 18-20 months
- may be stored in fridge 18-30 months
-IF injected cold may:
Cause delay of absorption rate
Set off local reaction
Cause discomfort
Documentation of insulin
Include:
- blood glucose level @ time of administration
- # of Units given
- site given
