Which of the following procedures is typically performed by a medical assistant?

The procedure of administering an intramuscular injection is indeed one that is typically performed by a medical assistant. Medical assistants are trained to give various types of injections as part of their role in providing patient care and supporting physicians. Intramuscular injections involve delivering medication directly into a muscle, which is a common practice in outpatient settings for vaccinations, hormone therapies, and other medications requiring rapid absorption.

In contrast, chest tube insertion is a more advanced procedure typically performed by physicians or specialized healthcare providers, as it requires specific training and skills to manage the potential complications involved. Endoscopy is also a specialized procedure that involves visualizing the interior of the body, usually performed by gastroenterologists or surgeons. Similarly, cardiac surgery is a complex surgical procedure that requires the expertise of a cardiothoracic surgeon and a specialized surgical team. Thus, the responsibilities of a medical assistant focus on supportive tasks and basic procedures, making intramuscular injections an appropriate and typical task within their scope of practice.
