Procedures for Administering the Three Types of Injections.
This lesson discusses the procedures for administering the three types of injections. The basic preparation (checking the doctor's order, washing hands, assembling needle and syringe, and drawing medication) is basically the same for all types of administering medication. Remember that this course by itself does not present sufficient training for you to be proficient in administering injections. You need "hands-on" training under the guidance of a qualified person before you begin administering injections.
2.0 General Information
An intramuscular (IM) injection is the preferred route of administering medication when fairly rapid-acting and long-lasting dosage of medication is required. Some medications that are irritating to the subcutaneous tissue may be given into the deep muscle tissue. Injection of medication into muscle tissue forms a deposit of medication that is absorbed gradually into the bloodstream. An intramuscular injection is the safest, easiest, and best tolerated of the injection routes. Remember the following guidelines:
a. The needle should be not less than one inch in length or more than one and one-half inches long (20 to 22 gauge). A needle one and one-fourth inches long (20 to 22 gauge) is commonly used.
b. A maximum volume of medication of five milliliters per injection can be administered at one site to an adult.
