NURS 3234 Chapter Notes - Chapter 10: Tuberculin, Greater Trochanter, Blood Vessel
Document Summary
Terminology: ampule: a sealed glass tube that holds medication. The top of an ampule is snapped away in order to access the medications, and it cannot be resealed: gauge: a term describing needle thickness. The higher the gauge number, the thinner the needle. Intradermal (intracutaneous) injection: the administration of a very small amounts of medication just below the skin. Intramuscular injection: a method used to administer medications into the deep muscle tissue. Injections into an existing intravenous line administer medications directly into the patient"s bloodstream bringing about an almost immediate effect. Draw an imaginary line from the trocanter to the iliac crest: the correct injection site is about 1 inch in an upward, inward direction from the center of your imaginary line. In the case of insulin, the subcutaneous site is used because a protein substance like insulin would be broken down and destroyed by the gastrointestinal tract.
