Final answer:
The first nursing action would be to assess the client's ability to participate in PT.
Step-by-step explanation:
The first nursing action for a nurse caring for a client that requires physical therapy (PT) after discharge would be to assess the client's ability to participate in PT. This is important because it helps determine the client's current physical condition and any limitations that may affect their ability to engage in PT.
By assessing the client's ability, the nurse can then determine the appropriate PT program and tailor it to the client's specific needs, ensuring they receive the best possible care and support. This assessment also helps in identifying any potential risks or contraindications that may require modifications to the PT program.
