Final answer:
The nurse should instruct the client to avoid bending beyond 90 degrees at the hip and crossing the legs while seated.
Step-by-step explanation:
The nurse should include the instruction to avoid bending beyond 90 degrees at the hip when reviewing hip precautions with the client. This is because bending beyond 90 degrees can put stress on the hip joint and increase the risk of dislocation or further injury. The client should also be taught to avoid crossing the legs while seated, as this can also increase stress on the hip joint. Sitting on low chairs without support is not recommended, as it can be difficult for the client to get up from a low position and may increase the risk of falls. Engaging in high-impact activities is not recommended for a quick recovery, as it can put excessive stress on the healing hip joint.
