AAMA CMA Practice Question

A medical assistant is preparing to administer an intramuscular injection to an adult patient. Given considerations for proper medication delivery and patient comfort, which needle length and gauge are most appropriate for this procedure?

  • 1.5 to 2-inch length, 20 gauge, as a one-size-fits-all solution for all intramuscular injections

  • 1 to 1.5-inch length, 22 to 25 gauge, depending on medication viscosity

  • 2-inch length, 18 gauge, to ensure medication reaches deep muscle tissue in all patients

  • 0.5-inch length, 28 to 30 gauge, to minimize discomfort
