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
