PARENTERAL MEDICATIONS Flashcards
angle of intradermal
10-15 degrees
angle of intravenous
25 degrees
angle of subcutaneous
45 degrees
angle of intramuscular
90 degrees
a type of syringe consisting of a hollow cylinder, usually of glass or plastic, a tightly fitting piston, and a hollow needle ( hypodermic needle ), used for withdrawing blood samples, injecting medicine, etc.
hypodermic
- 1cc syringe
- used for subcutaneous or intradermal injections of medicines, vaccines, or other substances
tuberculin
100 units syringe for insulin
insulin
recommended for immunization programmes because they are designed to prevent re-use by locking automatically after a single use
ADS / auto-disable syringe
push the hypodermic needle to the syringe end
non-luer lock / luer slip
requires the hypodermic needle to be screwed on, rotating the needle clockwise can achieve a very tight fit bond between the needle and the syringe
luer lock
recommended needle size for ID
23-27 gauge
recommended needle size for SQ
24-26 gauge
recommended needle size for IM
20-22 / 23-26 gauge
where to store syringes and needles after use?
puncture-proof disposal containers
true or false: never bend of break needles before disposal
true
true or false: you should recap needles after use
false - never recap used needles
how to properly recap needle/
one-handed scoop method / fishing method
a way to minimize discomfort and pain when administering injections is to apply ___ compress
cold
- slow absorbing
- can deliver only small amount of drug
- breaks skin barrier
intradermal
sites for ID injection
- beneath scapula
- upper chest
- inner lower arm
formula for skin test
0.9 cc saline + 0.1 cc drug
true or false: massage ID site after injecting
false
- onset of drug reaction faster than oral
- requires sterile technique
- breaks skin barrier
- more expensive than oral
- slower than IM
subcutaneous
some meds injected subcutaneously:
- insulin
- growth hormone
- epinephrine
- heparin
common sites for SQ injection
- outer aspect of upper arm
- anterior aspect of the thighs
- abdomen
guideline for administering insulin through SQ
needle should remain embedded for 5 seconds after pushing the plunger
what should you do when there is bleeding after SQ injection?
apply pressure
- pain from irritating drugs is minimized
- larger volume can be administered
- rapidly absorbed
intramuscular
common sites for IM injection
- ventrogluteal
- vastus lateralis
- rectus femoris
- deltoid
- dorsogluteal
max volume of meds for large muscle
3 ml
max volume of meds for babies, elderly, emaciated px during IM
2 ml
a technique in which the provider slightly pulls and holds pressure on the skin when giving an injection, which leaves a zigzag path behind when they remove the needle and release the skin
z-track method
best site for IM injections for infants, toddlers and children
vastus lateralis
- rapid effect
- limited to highly soluble drugs
- drug distribution inhibited by poor circulation
intravenous
___ equipment and drug solution are essential for all parenteral therapy or administration
sterile
