The nurse is caring for a client who is having a mitral valve replacement with a mechanical valve. What instructions should the nurse be sure the client understands prior to being discharged?
A) The valve should last for 10 to 15 years.
B) The client will require anticoagulation.
C) There is a low potential for thrombi formations so anticoagulation is not necessary.
D) The valve is prone to calcification.
B
Feedback:
A mechanical valve should last at least 20 years. The disadvantages are the risk for thrombi and emboli, so anticoagulation are necessary. There is a risk of bleeding, and there can be a sudden malfunction in the valve. An allograft will last 10 to 15 years. A bioprosthetic valve does not require anticoagulation but is prone to deterioration and calcification.
