A nurse is reviewing the discharge plan for a patient who has undergone hip replacement surgery. Which educational topic is most important to prevent postoperative complications?

Choice A reason: While weight management is beneficial for long-term joint health, it is not the most critical educational topic for preventing immediate postoperative complications. Discharge education must prioritize acute safety concerns and the recognition of life-threatening or surgical-failure events rather than lifestyle changes that take months to yield results. Choice B reason: There is no standard clinical requirement to avoid caffeine for 6 weeks following a total hip arthroplasty. While excessive caffeine might interfere with sleep or hydration, it does not pose a significant risk for surgical complications compared to the risk of sepsis, dislocation, or venous thromboembolism. Choice C reason: Infection is a major complication of joint replacement that can lead to surgical failure, hardware removal, or systemic sepsis. Instructing the patient on how to identify erythema, purulent drainage, increased warmth, or fever ensures early intervention, which is essential for salvaging the prosthetic joint and ensuring patient safety. Choice D reason: Planning a vacation is a secondary concern related to the patient's return to normal activities and psychosocial well-being. It does not contribute to the prevention of postoperative physiological complications and should not take precedence over instructions regarding wound care, activity restrictions, and medication adherence
