Step-by-step explanation:
The correct answer to the question is (c) A maximum of 6 combined PT assistants/techs per supervisor. This means that each supervisor can supervise up to 6 PT assistants or techs.
For example, if there are 12 PT assistants/techs, there would need to be 2 supervisors. If there are 18 PT assistants/techs, there would need to be 3 supervisors.
The supervision ratio is an important factor in ensuring that PT assistants and techs receive appropriate oversight and guidance from their supervisors to provide quality care to their patients.
