During weekly output QA on a linac, a reading comes back outside the department's tolerance limit, and physics has placed the unit on hold for review. The therapist must finish the log entry before the shift ends, and the department requires the reading, the limit it missed, and the response in the record. What should the QA entry for this out-of-tolerance result contain?
Select an answer to reveal the explanation.
Short Explanation
You’ll want the entry to show the measured reading, the limit it missed, what you did in response, and when and on which equipment the check occurred. That gives physics a clear record of both the finding and how you handled it. Documentation is part of the QA result, not a note to add later.
Full Explanation
The entry should include the measured reading, the tolerance limit it failed to meet, the steps taken in response, and the date, time, and equipment used. Together, these details make the out-of-tolerance event traceable and show both the finding and how it was handled. A record with the reading, limit, response, and check date and time still lacks the equipment used, so it may not establish which unit produced the result. A record with the reading, missed limit, response, and linac identifier lacks the date and time, making it difficult to place the event reliably in the QA timeline. A record with the reading, limit, date, time, and equipment used omits the response, leaving no account of the actions taken after the failure. Each incomplete record captures useful QA information but misses a distinct detail required here. Exam caveat: follow the department’s approved documentation and escalation procedure, since local forms may require additional fields or specific wording. Practical check: before signing, compare the entry with the QA worksheet and confirm that the result, applicable limit, response, timestamp, and unit identifier are all present.
