Final answer:
The nurse's initial action would be to set up appointments with the hospital PT department.
Step-by-step explanation:
The nurse's initial action after reading the healthcare provider's order for physical therapy (PT) for a client who will be requiring rehabilitation after a total knee replacement would be to set up appointments according to the order with the hospital PT department. This is because in the early stages, PT is usually provided in a controlled facility, like a hospital, where the therapist can closely monitor the client's progress and adjust the therapy plan as needed.
Home health agencies are typically involved in later stages of rehabilitation when the client is stable and able to continue therapy at home with the guidance and instructions provided by the hospital PT department. Discussing the various types of settings for therapy and teaching the exercises needed for the client are also important actions, but they would generally occur after setting up the initial appointments with the hospital PT department.
