Which statement indicates to the nurse that a client understands the post-operative care after a femoral head prosthetic insertion?

The statement indicating an understanding of post-operative care after a femoral head prosthetic insertion is the one that mentions using a raised toilet seat. This choice reflects knowledge of necessary precautions to ensure safety and comfort during recovery. After a hip replacement, patients often experience limited range of motion, especially in the early stages of recovery. A raised toilet seat can help prevent excessive hip flexion, reducing the risk of dislocating the new joint and making it easier for the patient to sit down and stand up.

The other statements do not demonstrate the appropriate understanding of post-operative care. Engaging in any physical activity immediately is not advisable as it could lead to complications or injury. Walking without assistance too soon can also pose a risk of falls and destabilization of the newly implanted prosthesis. While avoiding stairs altogether might seem cautious, it's important for the patient to understand safe mobility techniques with assistance or when cleared by a healthcare provider, rather than completely abstaining from stairs.
