What authority does the board have regarding the administration of oaths?

The correct choice highlights a specific power granted to the board, which is to administer oaths and summon witnesses. This authority is significant as it underscores the board's role in maintaining the integrity of its regulatory processes. Administering oaths is a procedural function that ensures that individuals are obligated to provide truthful testimony in any proceedings that the board conducts. Summoning witnesses further empowers the board to gather evidence and obtain testimonies that may be necessary for investigations into professional conduct or disciplinary matters.

This function is crucial in regulatory and disciplinary actions, allowing the board to uphold standards within the profession, ensuring that practitioners are held accountable for their actions. Such authority contributes to preserving the integrity and professionalism of the physical therapy field in Florida. Each of the other options pertains to different responsibilities that the board may hold, but they do not reflect the specific administrative function of handling oaths and witness testimonies, which is critical for effective oversight and governance within the physical therapy domain.
