Intramuscular Injection Quiz

What should you do for a patient who requires repeated injections? a. Massage the injection site. b. Rotate injection sites. c. Tap the injection site. d. Apply heat to the injection site before injection

b. Rotate injection sites. Rationale: Keep a rotation record that lists all available injection sites, divided into various body areas, for patients who require repeated injections. Rotate from a site in the first area to a site in each of the other areas.

What's the most commonly used site when giving an intramuscular (IM) injection to a healthy adult? a. Gluteus maximus b. Ventrogluteal c. Vastus lateralis d. Deltoid

b. Ventrogluteal Rationale: The ventrogluteal muscle is the most commonly used site for IM injection in adults because it can accommodate up to 5 mL of medication.

At what angle should you administer an intramuscular (IM) injection? a. 60 degrees b. 30 degrees c. 90 degrees d. 45 degrees

c. 90 degrees Rationale: To administer an IM injection, position the syringe at a 90-degree angle to the skin surface with the needle a few inches from the skin.

You're preparing to administer an intramuscular (IM) injection into the ventrogluteal muscle. Which landmarks should you use to locate the appropriate location? a. Anterior iliac spine and iliac crest b. Acromial process and axilla c. Posterior iliac spine and the greater trochanter of the femur d. Greater trochanter of the femur and the knee

a. Anterior iliac spine and iliac crest Rationale: To administer an IM injection into the ventrogluteal muscle, locate the greater trochanter of the femur with the heel of your hand. Then spread your index and middle fingers from the anterior superior iliac spine to as far along the iliac crest as you can reach.

What criteria should you use when determining which needle length to use for an intramuscular injection? a. Choice of injection site, the patient's size, and the amount of subcutaneous fat covering the muscle b. Viscosity of the medication, injection site, and patient's age c. Size of the syringe, the patient's age, and the choice of injection site d. Amount of medication to administer, viscosity of the medication, and amount of subcutaneous fat covering the muscle

a. Choice of injection site, the patient's size, and the amount of subcutaneous fat covering the muscle Rationale: Needle length choice depends on the injection site, the patient's size, and the amount of subcutaneous fat covering the muscle.

In which position should you place a patient to administer an intramuscular (IM) injection into the vastus lateralis muscle? a. Sitting position b. Standing position c. Lateral position d. Prone position

a. Sitting position Rationale: To administer an IM injection into the vastus lateralis muscle, have the patient sit or lie supine.

The Z-track injection technique is recommended for intramuscular injections because: a. it prevents drug leakage into subcutaneous tissue. b. it permits repeated injections at the same site. c. it creates a tunnel for drug absorption. d. it helps seal the drug into the dermis.

a. it prevents drug leakage into subcutaneous tissue. Rationale: By leaving a zigzag path that seals the needle track, the Z-track technique prevents drug leakage into the subcutaneous tissue, helps seal the drug in the muscle, and minimizes irritation.

The intramuscular route is commonly selected because it provides: a. decreased amount of drug absorption. b. absorption that's comparable to other routes. c. rapid systemic action. d. slow systemic action.

c. rapid systemic action. Rationale: Medications given deep into muscle give a rapid systemic action.

What should you do if blood appears when you're aspirating during an intramuscular (IM) injection? Continue the injection. a. Continue the injection. b. Stop the injection and massage the area. c. Stop the injection and clean the area. d. Stop the injection, withdraw the needle, and prepare a new syringe for injection in a new site.

d. Stop the injection, withdraw the needle, and prepare a new syringe for injection in a new site. Rationale: If blood appears when you're aspirating during an IM injection, the needle is in a blood vessel and you shouldn't inject the medication into that area. Instead, withdraw the needle and prepare a new syringe for injection in a new site.

Intramuscular (IM) injections are less painful for a patient than other types of injections because the: a. dermis has few sensory nerves. b. subcutaneous layer has few sensory nerves. c. fascia has few sensory nerves. d. muscle tissue has few sensory nerves.

d. muscle tissue has few sensory nerves. Rationale: The IM route is less painful for the patient because the muscle tissue has few sensory nerves.
