A nurse is caring for a client who is 3 days post operative from a right hip arthroplasty. While transferring to a chair, the client cries out in pain. The nurse should examine the client for which of the following manifestations of dislocation of the hip prosthesis?

A. Bulging in the area over the surgical incision: This could indicate a hematoma or fluid accumulation, not necessarily dislocation. B. Sensation of warmth over the surgical site: Mild warmth is expected postoperatively. Excess warmth may indicate infection, not dislocation. C. Shortening of the right leg: Limb shortening and external rotation are classic signs of prosthetic hip dislocation. This is a surgical emergency. D. Pallor following elevation of the right leg: Pallor may suggest vascular compromise, but it's not a hallmark sign of prosthesis dislocation.
