Dear Nancy,

Do medical assistants perform their duties under an RN’s or an NP’s license? Are they allowed to administer injections, such as hepatitis B or TB skin tests?


Nancy Brent replies:

Dear Carla,

The term “medical assistant” is a name that is applied with much variety in healthcare settings. Some have been trained by a physician or other healthcare provider in their office, while others have graduated from a school that prepares medical assistants to work in the healthcare field. Those who graduate from a school for medical assistants must pass a national exam and then are certified.

Medical assistants are required to work under a physician’s direction, but their duties and responsibilities vary from state to state. For example, some states require a phlebotomy course for medical assistants who draw blood, while other states do not. The decision as to whether they can do vaccinations, administer medications and other tasks, rests with the state agency and law that regulates medical assistants.
