Which of the following tasks can a Physician Assistant perform?

The task that a Physician Assistant can perform is conducting exams. Physician Assistants are trained healthcare professionals who work under the supervision of physicians. One of their primary responsibilities is to assess patients, which includes conducting physical exams, taking medical histories, and evaluating patients' conditions. They provide essential diagnostic and therapeutic services, allowing them to be integral members of the healthcare team.

The other options do not accurately reflect the typical scope of practice for Physician Assistants. Performing complex surgeries usually requires the skills and expertise of specially trained surgeons. Managing insurance claims is typically handled by administrative personnel or billing specialists, not clinical providers. Developing pharmaceutical treatments requires deep expertise in pharmacology and is generally within the realm of researchers or specialists in drug development, rather than the responsibilities of a Physician Assistant.
