Lesson 2: Procedures for Administering the Three
Types of Injections
a. The subcutaneous (SQ) method of injection is commonly ordered for medication that requires a slower absorption rate than IM injections provide.
b. The needle must pass through the epidermis and dermis to reach the subcutaneous fatty (adipose) tissue (see figure 2-7). Small volumes of medication that are voluble and nonirritating to body tissues are administered by this method. A variety of medications, such as insulin and some immunizations, are given subcutaneously.
a. Follow procedures outlined in paragraph 2-3.
b. Select injection site and position patient.
c. Prepare the Injection Site. Clean the site with an antiseptic pad using a circular motion from the center point outward about two inches.
d. Remove Needle Guard. The needle cover should be pulled straight off. Any twisting motion or a sideward motion may bend the needle. Do not touch the needle. Lay the needle cover on a clean, flat surface.
e. Stabilize Injection Site. Pinch up tissue on the upper arm or upper thigh, whichever you have chosen (see fig 2-7).
f. Insert Needle.
g. Aspirate the Syringe. Refer to paragraph 2-3n above.
h. Inject the Medicine. Press the plunger into the barrel with the thumb slowly and steadily until all medication is expelled. Medication should be injected slowly. Rapid injection will put pressure on the tissue and cause pain.
i. Remove the Needle. Place an antiseptic pad slightly above the injection site. Withdraw needle quickly at same 45-degree angle as inserted and bring pad down on injection site.
j. Massage the Site. Gently massage the injection site with an antiseptic pad after you remove the needle unless medication guidance indicates otherwise.
k. Cover Injection Site. Place an adhesive bandage over the injection site to protect clothes if bleeding occurs and to prevent infection.
l. Perform Postinjection Patient Care. Refer to paragraph 2-3u.
