Free AAMA Certified Medical Assistant (CMA) Practice Question

During an intramuscular injection using the Z-track method, you are required to administer an irritant medication that can cause staining of the skin. After positioning the needle at a 90-degree angle to the injection site and displacing the skin and subcutaneous tissues laterally, what should be your next step to correctly perform this method?

  • Inject the medication slowly and steadily, then wait 10 seconds before withdrawing the needle.

  • Aspirate for blood to ensure the needle is not in a blood vessel before injecting the medication.

  • Withdraw the needle immediately after injecting to prevent the medication from damaging tissue.

  • Release the displaced skin and subcutaneous tissues before injecting the medication.
