Giving injections Flashcards
where are drugs that are admin via the IM route deposited
vascular muscle tissue
what is the benefit of depositing drugs into the vascular muscle tissue
allows for rapid abs into circulation
the deltoid muscle in the upper arm is most commonly used, what are the benefits of this site
easy to locate and access
other sites aside from the deltoid muscle in the upper arm are used when the injection volume exceeds x ml
1
why should safety needles be used for im injections
reduce the risk of needle stick injury
needle sizes are measured in gauges aka the x of the needle
diameter
what does needle selection depend on
viscosity of liquid
Public Health England
25 and 38
for im injections into the deltoid muscle what angle should the needle be injected at
90 right angle
T/F you need to clean arm site w alcohol wipe before injecting
false
though some hospitals may require this- check guidelines
what injecting technique helps keep the administered medication within the muscle
z track
press and pull skin away and inject. when released, sites dont line up= med stays in muscle not leaked out to skin
why would you aspirate after putting needle into deltoid for DEEP im injection?
to check not put in blood vessel, if blood appears, remove syringe and prepare enw inj, explain to px
rec for deep im inj w high risk intravascular admin, not for shallow IM
inject im med at what rate?
1ml/ 10 secs
How to reduce pain caused by im injection
correct technique
rotate injection site
explain benefits
relax muscle
distraction
smooth and quick
hold syringe steady
what can be preventing by rotating the injection site of im injections
indurations or abscesses
what route allows drugs like insulin and lmwh be absorbed slowly over a period of time
SC
why is the absorption of sc slower than im
unlike muscle, SC tissue does not have rich blood supply
small volumes below x ml of non irritant water soluble drugs can be administered by sc route
2
list some recommended sites for sc administration
lateral aspects of upper arm and thigh
umbilical region of abdomen
back
lower loins
what is the risk of inadvertent im injection of insulin
quick absorption risking hypoglycaemia
what gauge needle is commonly used for sc injections
25
what length of needle is recommended for IM
4-8mm
phe recommend that sc injections are given at what angle
45-90
why should you wait 10 secs before withdrawing needle in sc admin
prevent backtracking of drug
why should you not massage the injection site
can lead to bruising
admin is recorded on prescription charts, why is it important to also record the admin site
avoid lipohypertrophy
give one reason why it is important that you avoid injecting short needle pens into muscle layers
more painful and could cause bruising and bleeding
