Rationale: The correct instruction the nurse should include is to avoid crossing the legs at the knees. This advice helps prevent dislocation of the new hip joint, which is a common concern after a total hip replacement surgery. Crossing the legs can place stress on the hip joint and increase the risk of dislocation. It is important for the client to follow this precaution to promote proper healing and reduce complications postoperatively.

Rationale: An Intracranial Pressure (ICP) of 20 mm Hg is at the upper limit of normal and may indicate increased intracranial pressure, which is a critical finding in a client with a severe head injury. Elevated ICP can lead to further brain damage and must be addressed promptly to prevent complications such as herniation. Monitoring and managing ICP are crucial in the care of patients with head injuries in the ICU.

Correct Answer: C

Rationale: Administering on-call sedation is crucial before a bronchoscopy to ensure the client is comfortable and adequately prepared for the procedure.
