Chapter 20 Part 2 Flashcards
drug
amount/dosage
patient
time
route
5 rights of drug administration
show assistant drug container before drawing it up
check 3 times
never use unlabled or expired
right drug
once when getting out of pixus or off shelf
when drug is removed from container (drawn up)
when container is replaced
check 3 times
right drug
measure carefully and accurately
use correct size syringe
right amount/dosage
ask patients name
check wristband
birthdate
right patient
physician or practitioner determined
NOT rad tech
right time
oral
sublinguil
topical
parenteral
right route
the way administered
most common route
make sure they are conscious
head elevated
oral
under tongue
allow to dissolve
never swallowed
nitroglycerin common one
sublingual
directly on skin
unit dosage device (transdermal patch)
precise dose released over time
topical route
by injection or route other than digestive tract
intramuscular(ex: epi-pen)
intradermal(ex: TB)
subcutaneous
intravenous(ex: IV)
parenteral
if drug is injected incorrectly may cause nerve damage and introduce microorganisms into system
parenteral
rapid onset
(ex: epi-pen)
intramuscular
like a TB test
intradermal
slow constant absorption
subcutaneous
immediate onset
intravenous
drug container
syringe
needle
angiocaths
supplies for injection
ampule
vial
IV bag
larger bottle
what drug comes in (containers)
sealed glass container
single dose
ampule
hold upright
flick top with fingers for contents to go to bottom
guaze around top
break at score line
do not contaminate needle as going into glass container
ampule method
small glass (plastic) bottle with sealed rubber top
vial
pull back plunger to get air in syringe then insert into top
held in non-dominant hand
syringe in dominant hand
hold uipside down
swipe top with alcohol wipe before needle insertion
vial method
plastic discard after use
tip
barrel
plunger
syringe
leur lock syringe
holds tip and needle in place
type of syringe
where needle attaches
tip
calibration scales
barrel
inside part that fits into barrel
plunger
use for precise measurement of small amount of drug
tuberculin syringe
insuline syringe
reduce number of needle sticks (white ring on port)
needless injection system
hub
cannula (shaft)
bevel
needle parts
refers to diameter
larger = smaller diameter
needle guage
18 gauge to draw up drug
smaller diameter to inject(25 gauge is common)
correct size
gauge information
refers to shaft (cannula) portion of needle
(.25-5 inches)
length
shorter needle
longer bevel (due to shallow angle)
subcutaneous injections
intramuscular injections
longer needle
rapid onset
example is epi-pen
angle at tip of needle
bevel
long bevel
shallow injection angle
subcutaneous injection
short(small) bevel
steeper angle
covers short distance
intravenous injection
leave catheter behind to administer drugs through
flexible less likely to harm vein
safer
angiocaths
when you pull needle out the needle is drawn into protective sheath
prevents unintended needle pokes for healthcare worker
angiocath safety
used for small veins
come in gauge sizes
butterfly needle
tourniquet
alcohol swab
betadine
cotton balls
gauze
latex free gloves
hypo allergenic tape
arm board
other parenteral supplies
absorbed directly into blood stream
more rapid onset of effects
route other than digestion
parenteral method of administration
the ability of a liquid to flow easily
viscosity
thicker fluid
flows slowly
high viscosity
25 gauge
45° angle for average patient
sites: thigh, upper back,upper arm, abdominal
subcutaneous (administration) injection
anterior thigh
upper back
outer surface of arm
lower abdomen
sommon sites for subcutaneious injection
90° angle of insertion
1-3 inches into body
19-25 guage needle depending on viscosity
intramuscular injection
deltoid muscle of upper arm
vastis lateralis muscle in lateral thigh
gluteus maximus muscle of the buttock
common site for intramuscular injection
check label 3 times
never use open container
check expiration date
good habit to not use drug someone else has prepared
if prepared for someone or by someone else, show bottle before use
preparing IV injection
when taken off shelf
when removed from container
when container is replaced
3 checks for correct drug
right drug
single administration
by Bolus or IV push
infusion of large volume of fluid
IV injection methods
drug injected slowly
single administration of IV injection
amount of fluid injected
bolus
rapid injection
IV push
called a drip infusion
certain amount of medication over time
IV infusion
monitor patient
if drip stops check injection site for infiltration
severe swelling and pain, stop immediately
apply warm cloth
IV drip precautions
name of drug
dosage
route of administration
localtion of injection
time administered
expiration date
lot #
documentation of drug administration
for tracking purposes incase of problem
documentation of lot #
basilic vein
cephalic and basilica veins
common IV injection sites
on posterior of hand
cephalic vein
basilica vein
on medial side of anterior surface of forearm or elbow
basilic vein
escape of drug out of the blood vessel into surrounding tissue
extravasation
infiltration
remove needle
apply pressure
hold warm compress on site
get nurse
extravasation/infiltration procedures
gadolinium based (rare earth metal)
most common MRI contrast material
shorten relaxation time of atoms in body
what contrast accomplishes
orally or IV
contrast administration
magnevist
omniscan
optimark
brands of contrast
kidney disease
renal failure
contrast is contradicted in these patients
get into connective tissue and harden them
result of contrast in patient with renal problems
