HSC 343 EXAM QUESTIONS WITH 100%
CORRECT ANSWERS
What is the onset and duration of regular insulin?
Onset: 0.5-1 hour
Duration: 6-10 hours
Humulin R
Regular insulin is a drug but it also is what our pancreas secrete
What is the onset and duration of NPH insulin?
INTERMEDIATE ACTING
Onset: 1-2 hours
Duration: 16-24 hours
Humulin N, NPH
What are the S&S of an insulin overdose?
hypoglycemia (weakness, sweating, headache, ↑ HR, anxiety, tremor, mental/visual
disturbances)
Insulin overdose is all due to what?
hypoglycemic release of epinephrine, and hypokalemia (insulin drives K+ from serum into cells).
How do you treat an insulin overdose?
conscious give them something to eat such as sugar
If a patient regularly takes insulin in the abdomen, how will the onset differ if taken in the
arm?
The onset will take longer
,Onset and duration of insulin Glargine
LONG ACTING
Onset: 1 hour
Duration: 24 hours
Lantus
Onset and Duration of insulin Lispro
RAPID ACTING
Onset: .25-.5 hour
Duration: 3-6.5 hours
Humalog
Onset and Duration of insulin Aspart
RAPID ACTING
Onset: 0.2-0.3 hour
Duration: 3-5
Aspart
Absorption from different anatomical
sites from insulin
Insulin given SC. Absorption is greatest
from abdomen>arm>
thigh>hip.
How many injections do most people need per day?
Most people need 2 injections/day of regular/NPH mixture.
What increases/decreases insulin need?
, Food, stress, and infection increase insulin need
Exercise decreases insulin need
How to mix insulin
When mixing Insulins, draw up the SHORT-ACTING insulin into the syringe first, then NPH
(which is cloudy insulin)
This way you will not contaminate the short-acting insulin with NPH!
Endocrine System MOA
Hypothalamus (Releasing Hormone)
Pituitary
(Stimulating Hormone)
Endocrine Gland
(Effector Hormone)
Which insulin is cloudy?
NPh
What insulin can be given IV?
Regular, Aspart, Lispro and Glulisine
Insulin Glargine (Lantus)
Long-acting. Used for adults and children with type 1 DM, or type 2 DM patients needing a
long-acting insulin. Injected SC once daily at bedtime.
Insulin Glargine (Lantus) Risks
Beware of hypoglycemia! Works better with people who have a fix diet! Do not give IV, do not
mix with other insulins
Insulin Aspart (Novolog)
