Final answer:
Supervision of a PTALA must be by a licensed PT who is in immediate proximity to the PTALA, meaning they must be present and immediately available in the same facility.
Step-by-step explanation:
The supervision of a Physical Therapist Assistant License Applicant (PTALA) must be provided by a licensed Physical Therapist (PT). According to guidelines, the correct level of supervision is:
2) By a PT and in the immediate proximity of the PTALA
This means that a licensed PT must be physically present and immediately available in the same facility to provide direction, assistance, and oversight as needed during the time the PTALA is practicing. It is not sufficient for the supervising PT to be nearby; they must be in a position to respond instantly, which rules out option 1. A Physical Therapist Assistant (PTA) cannot supervise a PTALA, which eliminates options 3 and 4.
