Endocrine glands
ductless glands that empty their secretions directly into the bloody stream
Hormones
chemical substances secreted by the endocrine glands
Pancreas
Beta cells of the Islet of Langerhans in the pancreas produce the hormone insulin
Insulin
hormones that regulate glucose metabolism and the transporting of glucose across the cell membrane
Indication
Diabetes Mellitus is a disorder of carbohydrate
Classification of Diabetes
Type 1: (IDDM) Insulin dependent diabetes mellitus=little to no insulin produced
Type 2: (NIDDM) non-insulin dependent diabetes mellitus=decrease in production of insulin, decrease in cell sensitivity to insulin, onset insidious, can treat with oral drug and/or insulin
Forms of Insulin
Animal:
1-Porcine: Pig
2-Bovine: Beef
Human
1-Synthetic: Humulin
2-Semisynthetic: Novolibn
Insulin strength/concentration
u100=every 1ml contains 100u
u500=every 1 ml contains 500u
u30
Insulin routes(SubCu)
1-Abdomen 2-Back of arm 3-Front of thigh 4-upper buttocks
- 90 degree angle
- no massage area
- massage will increase absorbtion rate
- rotate injection site to prevent lipodystrophy
Insulin routes(Insulin pump)
- must be able to follow direction
- human insulin in pump
- either rapid acting or short acting
- subCu
- can stay in place for 2-3 days
Insulin routes(IV/IVP)
-iv push and bolus dose
Classification
1)rapid 2)short 3)intermediate 4)Long acting 5)mixed insulin
properties- protein-decrease rate of absorption zinc-modify onset and duration -dose-determined by HCP -frequency once or twice a day
Rapid Acting Insulin

onsent: 15mins, novolog 10-20mins
peak: 1-2hrs
duration: 3-4 hrs
route: SC
hypoglycemia: before lunch
Short Acting Insulin
route: SC, only IV route
Insulin Regular(Humulin R, Novolin R)
- onset:30-60mins
- peak:2-4hrs
- duration:5-7hrs
- route:SC
- hypoglycemia before lunch
(IV) Insulin Regular(Humulin R, Novolin R)
route: iv
onset: 10-30min

Lispro protamine and lispro(Humalog 75/25,Humalog 50/50) onset: 15-30min, peak: 4-8hrs, duration: 24hrs, route: sc
mixing insulin
- intermediate and mixed insulin=cloudy
- rapid, short, long=clear
- rotate in palms of hand to warm
- do not mix levemir/lantus(long acting insulin)
- air goes in cloudy first then clear, clear is withdrawn first then cloudy
- long lasting insulin is design to meet basal needs last for 24hrs period, pt should be educated to take at night, once a day, at the same time
storage of insulin
-stored in refrigerator unopened and unused, once open stored at room temp for a month
frequency of insulin
fingerstick AC(before meals) HS(hour of sleep)
- q6h if npo
- urine glucose, use fresh urine on second void
Hypoglycemia(side effects)
- N/v
- diarrhea, hunger, inability to concentrate
- confusion
- nervousness
- anxiety
- tremors
- tachycardia
Hypoglycemia(causes)
insulin reaction/shock
- too much insulin or wrong type
