When assessing a patient for readiness for discharge post-hip arthroplasty, which criterion is most critical?

Choice A rationale Safety during mobility is the most critical factor for discharge after a major orthopedic procedure like a hip arthroplasty. The ability to navigate stairs safely demonstrates sufficient muscle strength, balance, and adherence to weight-bearing restrictions. This functional independence is vital to prevent falls and hip dislocations in the home environment. Without this skill, the patient is at high risk for readmission and serious injury, making it the priority assessment before leaving the facility. Choice B rationale While pain management is important, expecting a patient to be completely independent of all pain medication shortly after a total hip replacement is unrealistic. Most patients will require a combination of around-the-clock non-opioids and as-needed medications to maintain comfort and facilitate physical therapy. The goal is controlled pain that allows for movement, not the total absence of medication. Therefore, this is not a mandatory or realistic criterion for immediate discharge. Choice C rationale Complete healing of a surgical wound takes weeks or months as the tissue goes through the proliferative and remodeling phases. At the time of discharge, which is often a few days post-surgery, the incision should be clean, dry, and intact with no signs of infection like purulent drainage or excessive redness. Expecting a completely healed wound site before discharge is not standard practice and would unnecessarily prolong the hospital stay beyond what is medically required. Choice D rationale Understanding the need for follow-up care is an important part of the discharge teaching plan, but it is not as critical as the patient's immediate physical safety and mobility. While knowing to see the surgeon in six months is helpful for long-term monitoring of the prosthetic joint, it does not address the immediate postoperative risks the patient faces in the first few days at home. Physical stability and safety always take precedence over long-term scheduling.
