seminar 4 injections Flashcards
how would you know if you need a bigger syringe for an injection you are giving
if the syringe is more than 2/3/75 % full than a bigger syringe should be used
what determines the gauge of needle that you would use during an injection
-Viscosity of medication
-location of injection
-Type of injection (ie SC or IM)
what things need to go on a syringe label
-2 client identifiers
-Name of medication
-dose/volume
-route
which size of syringe would you typically use for a subQ injection
usually a 1-3 mL syringe
how much fluid is usually injected with a subQ injection
usually less than 1 mL
when would you administer a SubQ injection at a 45 degree angle
if 2.5 cm of tissue can be grasped at the site
when would you administer a SubQ injection at a 90 degree angle
if 5 cm of tissue can be grasped at the site
Do you rotate subQ injection sites
Yes and rotate body site completely if it is not insulin
what are good locations for subQ injections
anywhere that you can pinch an inch
where is the preferred site for heparin injections
usually in the abdo (other sites can be used) and at least 5cm away from umbilicus
what angle is heparin injected at
90 degrees
what order do you draw insulin
-for inserting the air go cloudy to clear
-for drawing the insulin clear to cloudy
(remember R-N so regular insulin which is clear to NPH insulin which is cloudy)
what are the sites in order of how fast they absorb that insulin is injected
abdomen is the quickest then arms then thighs then buttox
how many mL do you need to prime a subQ butterfly with
prime with 0.21 mL
how long can a subQ butterfly be used for?
can be used for up to 7 days
what size of syringe do you use for an IM injection
usually a 1-3 mL syringe
what is the prefered site for an IM injection in adults
Ventrogluteal
how many mL is typically administered in an IM injection
usually 3mL
what structures would you use to landmark an IM injection into the ventrogluteal area
-greatertrochanter (the bump of your hip)
-Iliac crest
-anterior superior iliac spine (the ridge thats in front of the iliac crest
how many mL can be injected to the deltoid
up to 2 mL
how do you landmark for a deltoid injection
inject 3-5 cm below the acromion process
how many mL can be injected into the vastus lateralis
up to 3 mL
how do you landmark for a vastus lateralis injection
inject into the outer middle third of the thigh
how many mL can be injected into the rectus femoris
up to 3 mL
where do you inject if you want to inject into the rectus femoris
the front of the thigh
do you ever inject into the dorso gluteal area
no not a site of injection that is used anymore
what are some risks associated with IM injections
Pain
Tissue necrosis
Hitting bone
injury to blood vessels
what are some risks associated with SC injections
-accidental injection into IM or IV
-lipohypertrophy
-infection
what is lipohypertrophy
when fat tissue builds up from giving an injection in the same spot to many times
what does the gauge on the needle refer to
The diameter of the inner lumen of the needle
what is the best gauge to use for an IM injection
22 G
