The nurse is caring for two clients who recently had open heart valve replacement surgery. One received a tissue (or biologic) valve replacement and the other a mechanical valve replacement. Which information should be omitted/excluded from the teaching plan for the client with a tissue valve?

Choosing between a mechanical and tissue valve involves weighing the thrombogenic risk against the structural durability of the prosthesis. Tissue valves are less prone to clot formation but have a shorter lifespan, whereas mechanical valves are highly durable but require strict pharmacological management to prevent thromboembolism. A. Assessment for signs and symptoms of heart failure is a critical component of teaching for all valve replacement patients. Regardless of the type of valve used, the patient must be monitored for signs of valvular dysfunction, such as weight gain, edema, or dyspnea, which could indicate the new valve is failing. B. Participation in a cardiac rehabilitation program is highly recommended for all patients following open-heart surgery. These programs provide supervised exercise and education to improve cardiovascular efficiency and facilitate a safe return to daily activities, regardless of whether a tissue or mechanical valve was implanted. C. Care of the surgical incisions is essential teaching for any patient who has undergone a sternotomy or thoracotomy. Preventing surgical site infections through proper wound care and monitoring for redness or drainage is a priority for any postoperative cardiac patient to ensure successful healing. D. Lifelong anticoagulation therapy, typically with warfarin, is mandatory for mechanical valves because their non-biological surfaces are highly thrombogenic. Tissue valves (bioprosthetic) do not require lifelong anticoagulation, usually only requiring short-term therapy or daily aspirin, making this instruction unnecessary and incorrect for a client with a tissue valve.
