What is the annual stereotactic accessories/lockouts tolerance?

• A. functional
• B. non-functional
• C. partial
• D. conditional

Answer: (A)

The annual tolerance for stereotactic accessories/lockouts is testing whether these safety-critical components are functioning properly. For an annual check, you want to confirm that the accessories and lockout mechanisms operate as intended under normal conditions, providing reliable locking, release, and interlocks during treatment. That’s why the best choice is that they are functional — a pass means the safety features are performing their job correctly. If a device were non-functional, it would fail the test and need service; partial would imply incomplete operation, and conditional would suggest it only works under certain circumstances, which isn’t acceptable for a universal annual safety check.
