What action must a PTA take when there is a change in a patient's condition?

When there is a change in a patient's condition, the appropriate action for a Physical Therapist Assistant (PTA) is to notify the supervising physical therapist immediately. This is crucial because the supervising physical therapist is responsible for the overall management of the patient's care, and any changes in a patient's status may require adjustments to the treatment plan or further evaluation. Timely communication allows for prompt decision-making which can significantly influence the patient's recovery and safety.

This action aligns with professional standards and best practices in physical therapy, ensuring that the collaborative approach to patient care is upheld. Attention to changes in a patient's condition is critical, as neglecting to communicate such changes could lead to inappropriate or ineffective treatment, potentially compromising patient safety and outcomes.
