Learning Injections

Tonya Eddy, RN, PhD

Current Standard

• "Give medications using enteral (oral,

sublingual, rectal, and buccal), parenteral (inhalation; intravenous, subcutaneous, and intramuscular injections; topical, transdermal) route of administration appropriate to the drug and the patient."

What to cover today:

• Available sites
• Needle selection
• Syringe selection
• Injection technique
• Hands-on Practice!

Let’s Start at the Very Beginning…

Available sites: frequently depends on medication needed, based on absorption needs.

• Intramuscular (IM) sites: ventrogluteal, deltoid,

vastus lateralis, rectus femoris (dorsogluteal not recommended)

• Subcutaneous (subq) sites: Back of the arms, top of

thigh, abdomen, lower back

• Intradermal (ID) sites: scapular, ventral forearm

IM Injection sites

Subq sites:

• Selection based
• n absorption

needs

ID sites:

• PPD’s
• Allergy testing

Needle selection

• Length: based on type of injection, selected site and size
• f client
• IM = 1-1.5 inches * ID = 0.5 inch or less
• Subq = 0.5 – 1 inch
• Gauge:
• needle diameter is numbered backward: 16 gauge is bigger

than 24 gauge

• Gauge selection is based on the viscosity of the fluid to be

injected

• Gauge of needle is what causes discomfort, not length

Syringe selection

• Based on amount of fluid to be administered and need for

accuracy

Drawing up medication

• Cleanse top of vial with

alcohol

• Inject amount of air equal

to amount to withdraw

• Without removing needle,

tip system and withdraw fluid

Prepare site

• Alcohol to intended site
• Gloves
• Pinch for subq
• Stretch for IM
• Pull taught for ID

Injection procedure

• IM: inject needle at 90 degree angle
• Subq: inject needle at 45-90 degree angle

depending on subcutaneous layer thickness

• ID: inject at 15 degree angle just past bevel
• Insert fast, inject slow for dispersion, withdraw

fast

Now let’s practice!!!!!
