Final answer:
The therapist should adjust the client's position using props like pillows or wedges to ensure comfort and safety during the session.
Step-by-step explanation:
If a client is unable to lie on her back with her legs straight out or head flat on the table, the therapist should adjust the position of the client to ensure comfort and prevent strain or pain. Accommodations such as using pillows or wedges for support, adjusting the headrest, or allowing the client to lie on their side can be made. Client comfort and safety should be the top priority during therapy sessions.
