Study Notes
Deltoid
- Injection site located two to three fingers below the acromion process, above the axillary line.
- Administer 0.5-1 mL of clear, non-irritating solutions.
- Patient should relax arm at the side and flex the elbow.
Vastus Lateralis
- Injection site determined by dividing the upper leg into thirds using the greater trochanter and patella.
- Administer in the middle third, lateral aspect of the vastus lateralis muscle.
- Preferred site for infants, toddlers, and children during immunizations; patient may lie flat with knees bent or sit.
Ventrogluteal
- Locate injection site by placing the opposite palm on the greater trochanter and thumb pointing towards the groin.
- Index finger on the anterior superior iliac spine, spread fingers toward the midline.
- Injection given between index and middle fingers into the gluteus medius muscle; patient should lie on their side.
Needle Identification
- Needles categorized by two numbers: length and gauge.
Needle Length
- Measured in inches.
Needle Gauge
- Refers to the diameter of the needle.
Gauge and Diameter Relationship
- Larger gauge number equates to smaller diameter needle.
Needle Packaging
- Needles are pre-packaged in standard sizes that accompany syringes for intramuscular (IM), intradermal (ID), subcutaneous (subcut), and intravenous (IV) injections.
Intradermal
- Needle gauge ranges from 26 to 27.
- Needle length is 1/4 to 3/8 inch.
- Commonly used for diagnostic tests and sensitivity determination; primary injection site is the inner forearm.
Subcutaneous
- Needle gauge ranges from 25 to 28.
- Needle length is typically 1/2 to 5/8 inch (up to 7/8 inch for obese patients).
- Frequently used for insulin and heparin administration; can also be utilized for fluid administration.
Intramuscular
- Needle gauge ranges from 21 to 23.
- Needle length is generally 1 to 1.5 inches.
- Longer needles suitable for irritating medications; larger gauge (20 G) preferred for viscous solutions.
Intravenous
- Needle gauge between 18-24, with options including 16.
- Length varies depending on equipment (1/2 to 1.5 inches).
- Commonly used for blood tests, IV fluids, electrolyte solutions, and blood transfusions.
Intracardiac
- Needle gauge is 26.
- Length is 4 inches.
- Designated for emergency use only by qualified healthcare providers.
