Which of the following statements is true regarding medical assistants?

The statement that medical assistants are legally bound to obtain continuing education to maintain a license is accurate, particularly because many states and professional organizations require this for certification renewal. Continuing education ensures that medical assistants stay current with the latest medical practices, technologies, and regulations, which is essential in a rapidly evolving healthcare environment. While the scope of practice may vary by state, the emphasis on ongoing education and training remains a key aspect of maintaining professional competency in the medical field.

In contrast to this, the other statements do not correctly represent the role of medical assistants. They do not require direct supervision by a physician or nurse at all times, and they do not need a license to practice in all states, as many are certified rather than licensed. Moreover, while their duties may overlap with those of Certified Nursing Assistants, medical assistants typically have a broader scope of practice that includes administrative tasks, which differentiates their role from that of CNAs.
