There is better medication absorption with IM injections True False
True
What degree is used for IM injections
90 degrees
You should massage a Z-track injection site True False
False
Technique to Sub-q injections
- 45 or 90 degree angle - pinch an inch - average to thin (not necessary in case of ample fat - inject slowly - wait 1 seconds before withdrawing needle (prevents leakage)
ID injections are used for
- allergy testing - administration of the TST (PPD) (Mantaux test)
Key points for ID injection
- hold skin taught - bevel UP - parallel to pt skin @ a 5-15 degree angle - insert needle slowly about 3mm (1/8) inch - bevel should be visible under skin - release skin, DO NOT aspirate - slowly inject creating a pale wheal - blot any blood; do not rub or cover w/bandage
Sub Q syringe size
1-3ml
Needle gauges used for ID injection
25-28 G that is 3/8 - 5/8 inches long
Sub q needle size and length
3/8 - 5/8 needle (obese pts may need longer) 25-27 G (can go up to 31G)
What angle do you give Sub-q injections
45 or 90 degrees
Injection degree for ID
5-15 degrees
Arm
Deltoid
Needle size for IM injection
Dependent on: - viscosity of med - pt muscle mass - 21-25 G needle - 1-3 inches long
Syringe size for IM injection
Dependent on: Volume of med Viscosity of med Patient muscle mass Usually between 1-5 mL
Why should you aspirate for IM injections?
Depending on the angle, to make sure that you are not injecting into the venous system (when aspirating, if you see blood, pull out because you are in a vessel)
You should always expel the nitrogen bubble from syringe for sub-q injections True False
False
Which medications should you NOT massage area of Sub-Q injection site?
Heparin LMWH Insulin
What types of medication is given Sub-q
Heparin/LMWH Insulin
Sub-q insulin site
Lateral aspect of mid upper arm Abdomen Front of thigh
Syringes used for ID injection
TB (tuberculin) syringe 1 mL syringe
What will you see when you do an ID injection?
Wheal
What is the point of the Z-Track method?
Zigzag path prevents the medication from reaching the subcutaneous layer or skin surface by sealing off the needle track.
