Select all that apply. 1. Biological valves have a higher incidence of clot formation than do mechanical valves.
2. Biological valves wear out faster than mechanical valves.
3. Mechanical valves sometimes have an audible click.
4. Infections are harder to treat in mechanical valves.
5. There is a higher risk of hemorrhage in the years after surgery if a biologic valve is used.

Rationale 1: The incidence of clot formation is higher in mechanical vales than in biological valves.
Rationale 2: Mechanical valves wear out more slowly than biological valves.
Rationale 3: Mechanical valves may make an audible clicking noise with each beat.
Rationale 4: Should an infection occur in a mechanical valve, it can be difficult to treat. Infections in biological valves are easier to treat.
Rationale 5: The risk of hemorrhage is related to anticoagulation, which is not necessary with biologic valves.
