stationary? - CORRECT ANSWER hip center, combined accuracy
check
14. After capturing hip center, you receive the unable to find
accurate hip center warning. The patients femoral head could have
dislocated, causing this warning. - CORRECT ANSWER true
15. After capturing hip center, you receive the unable to find
accurate hip center warning. This could have occurred if the femoral
array dropped out of the cameras field of view during the capture
process. - CORRECT ANSWER fasle
16. After capturing hip center, you receive the unable to find
accurate hip center warning. This could have occurred if the tibial

process. - CORRECT ANSWER false
,17. After capturing hip center, you receive the unable to find
accurate hip center warning. This could have occurred if the leg was
rotated in the wrong direction during the capture process - CORRECT
ANSWER false

the checkpoint was not put into hard and solid bone. - CORRECT
ANSWER true
20. When verifying the femoral checkpoint to enter bone prep, the
checkpoint result is greater than 1.0mm. This could have occurred if
the surgeon incorrectly placed the probe in the tibial checkpoint. -
CORRECT ANSWER true
21. When verifying the femoral checkpoint to enter bone prep, the

the femoral array was bumped. - CORRECT ANSWER true
22. After completing bone registration of the femur, the registration
result is greater than 1mm. This could have occurred if the
osteophytes were not segmented. - CORRECT ANSWER true
23. After completing bone registration of the femur, the registration
result is greater than 1mm. This could have occurred if the
osteophytes were removed before bone registration - CORRECT
ANSWER true

result is greater than 1mm. This could have occurred if the surgeon
pressed too hard with the probe when selecting points - CORRECT
ANSWER true

continues to be 1mm or higher. What should you do? - CORRECT
ANSWER confirm you have the correct patient information
recapture patient landmarks
check CT landmarks
confirm you have the correct operative side
28. After completing bone registration of the tibia, the registration
result is greater than 1mm. This could have occurred if the incorrect
operative side was selected. - CORRECT ANSWER true
29. After completing bone registration of the tibia, the registration
result is greater than 1mm. This could have occurred if the wrong
patient was selected. - CORRECT ANSWER true
