Question

For subcutaneous, intramuscular, and intradermal injections, research and describe the following: sites of administration, maximum volumes for each injection type, needle length and gauge ranges, type of syringe needed, and angles of needle insertion. How do you locate the injection sites? Why is it important to be sure that the correct needle size is used and to insert at the proper angle? Describe in detail what you would do if your dosage calculation exceeded the maximum volume allowed for the injection type and site.

Answer 1

A) Injection is a technique for delivering dongs by parenteral administration. That is, administration via a route other than trait. digestive Parenteral infection includes subcutaneous csc) > Intra muscular (IM) > Intravenous (IV) > Intra peritoneal (IR) > Intra cardiac (1) Intra articular CIA) > Intra cavernous injection. Types of injection siter:- Intramuscular (IM): - > An injection into muscle tissue (typically < 3 mL). Is large volumes require larger muscles Cegir vastus lateralis) > Smaller volumes Cup to IML) can be administered into smaller muscles (Deltoid). > Muscle sites should have good blood supply which helps the Medication to be absorbed more rapidly than sc route. subeuntaneous (se): Is Injection puto fatty layer which lies beneath the dernier se is for small volume injections <1 mL > Blood supply is less than muncle issue.
