Final answer:
PT/PTA conference documentations are held as needed, not on a fixed schedule. They occur to discuss and assess patient care, progress, and treatment plans. The correct frequency for these meetings is when the patient's condition or care necessitates it.
Step-by-step explanation:
PT/PTA conference documentations, which refer to meetings between a Physical Therapist (PT) and a Physical Therapist Assistant (PTA), are held as needed. These meetings are essential for discussing patient progress, treatment plans, and any adjustments that might be required. The frequency of these discussions is not fixed to a specific timeline such as annually or biennially, but occurs based on the requirements of the patient's care, changes in their condition, or when there is a need to reassess treatment goals. Therefore, option d. As needed is the correct answer to when PT/PTA conference documentations are held.
