Who holds strict responsibility for discharge, evaluation, and reevaluation?

The correct choice is the physical therapist, as they are the professionals responsible for the overall management of patient care within a physical therapy setting. This includes critical tasks such as the discharge of patients, as well as their evaluation and reevaluation throughout the course of treatment.

Physical therapists are trained to assess a patient's progress and determine when it is appropriate to discharge them from services or when further intervention may still be necessary. They possess the qualifications to conduct comprehensive evaluations that inform treatment plans and the decision-making process regarding a patient's ongoing care.

The physical therapist assistant, while valuable in helping implement the treatment plans established by the physical therapist, does not hold the same level of responsibility for discharges or evaluations. Board members and the patient’s primary care physician also have roles in patient care, but they do not directly manage the therapeutic processes and responsibility inherent in discharges and evaluations in the same way that physical therapists do. Thus, the physical therapist has the ultimate responsibility for these critical aspects of patient care in the physical therapy environment.
