Types of Injection Flashcards

Study Notes

Subcutaneous Injection (SC)

Administered at a 45° angle
Common sites: upper, outer arm; abdominal area; upper thigh
Volume: typically not more than 2 mL
Needle length: 1/2 to 5/8 inch; gauge: 25G to 27G
Common uses: insulin, allergy injections, immunizations

Intradermal Injection (ID)

Administered at a 10 to 15° angle
Used primarily for allergy testing and tuberculin testing
Administered just below the skin's surface with a fine gauge needle (26G or 27G)
Needle length: 3/8 to 5/8 inch; bevel facing upward to form a wheel or lump

Intramuscular Injection (IM)

Administered at a 90° angle
Directly injects medication into muscle tissue
Common sites:
- Deltoid (upper, outer arm)
- Ventrogluteal (lateral hip)
- Vastus lateralis (mid-portion of thigh)
- Dorsogluteal (upper, outer hip)

Z-track IM Injection

Administered at a 90° angle
Involves displacing muscle tissue to prevent leakage of medication

Dorsogluteal Site

Located in the upper-outer quadrant of the buttocks
Ideal for large-volume IM medications

Ventrogluteal Site

Identified by placing the palm over the greater trochanter of the hip
Thumb points toward the groin; index finger towards the anterior superior iliac spine

Vastus Lateralis Site

Located in the thigh region
Commonly used for IM injections, especially in infants and children

Deltoid Site

Identified by placing four fingers across the deltoid muscle
Top finger aligned with the acromion process for accurate placement
