Which task is not performed by PAs?

• A. Physical examination
• B. Ordering labs
• C. Prescribing antibiotics
• D. Fluoroscopy

Answer: (D)

Understanding this question comes down to the typical scope of practice for physician assistants. PAs are trained to perform comprehensive patient assessments, conduct physical examinations, order and interpret labs, and manage treatment plans, including prescribing antibiotics, all under physician supervision. Fluoroscopy, on the other hand, is a radiologic imaging technique that requires specialized equipment, radiation safety oversight, and personnel trained in radiology. While a PA may order fluoroscopy or use fluoroscopic guidance as part of a procedure in certain specialty settings, the act of performing fluoroscopy itself is not a standard independent duty of a PA. That imaging role is generally carried out by radiology staff and radiologists. So fluoroscopy is not something PAs routinely perform, whereas physical examinations, ordering labs, and prescribing antibiotics are all within the expected clinical responsibilities of PAs.
