- Deltoid limit to 1 mL. 1-1.5 in needle
- Aqueous solutions- 20 to 25 g
- oil-based- 18-25 g
- 1-4 mL
- children, elderly- 1-2 mL IM injections
- 26-27 g, usually less than 0.5 mL dose
- 1/4-1/2 in needle

- the effect of the body in the drug;
- movement of drug molecules in the body in relation to the drugs absorption, distribution, metabolism and excretion.
Commom Drug preperations
Capsule, elixir (med in liquid), enteric coated (prevent stomach irritation), extended release, liniment (rubbed into skin), lotion, lozenge (candy?) ointment, pill, powder, solution, suppository, suspension, syrup, tab, transdermal patch
Where does metabolism Primarily occur?
Why would the elderly have hard time metabolising (breaking down drugs)? (Biotransformation)
due to the aging process the liver has impaired functioning
Where does excretion of drugs primarily occur?
KIDNEYS, or lungs if drugs were inhaled
Distribution of drug in body
depends on the blood flow to the tissues, drugs ability to leave the bloodstream, and drugs ability to enter the cells
process were drugs alter cells physiology and affect the body
Anaphylactic reaction (Anaphylaxis)
life threatning and results in respiratory distress, sudden severe bronchospasms and cardiovascular collapse.
Unusual response to med
IM injection sites
- Deltoid (toddlers, adults) 5/8-1.5
- Vastus lateralis (infants, toddlers) 5/8-1in
- Ventrogluteal (adults) 1.5
- faster onset than SubQ
ID injection sites
- upper back
- under scapula
potential to cause developmental defects in fetus
Expected responses to meds based on ...
18-65 year old adults, 150 lbs
highest plasma concentration, should be measured when absorption of drug is complete.
drug at lowest concentration, specimen usually drawn within 30 mins interval before next dose.
amount of time it takes for 50% of blood conc of a drug to be eliminated from the body
carried out as specified until it is cancelled out by another order

Preferred system for Measurement of Drug Admin?
What should be done when admin of meds though NG tube?
- Powders or crushed tabs must be mixed with 15-30 mLs
- Check placement of tube
- Flush with 15-30 mLs of water
- if connected to suction, disconnect for 20-30 after adim of meds.

up to 1 week
Metric units of measurements?
- Meter (length)
- Liter (volume)
- Gram (weight)
3 Times the label should be checked during med prep and admin?
- 1. when reaching for container

- 3. when putting container back and before giving to pt
When are 2 witnesses needed in drug admin?

how long is a multidose vial good for?
Example of med that comes prefilled and should not have air expelled from syringe...
- Lovenox (enoxaparin)
- also provided in prefilled cartidges
First thing to do when going to mix 2 meds in one syringe?
Make sure the 2 drugs are compatible! do not mix more than 2 drugs in one syringe
Draw the med in the (BLANK) vial into the syringe FIRST.
- this prevents contents of the multidose vial from being contamined with meds inthe single dose vial.
