A medical technologist, Dan, received chemistry samples, including one from a patient, coded 556969, at basal state at 8AM for FBS testing. Unfortunately, Dan had to troubleshoot the chemistry analyzer, thus having to delay all chemistry tests for the AM shift. As a preventive measure, he refrigerated all the samples and endorsed them to the PM shifter, Ces. Ces managed to measure the glucose level of patient 556969 at 3PM, which was 120 mg/dL. If you were Ces, will you release the result as 120 mg/dL?
- A.
  
  Yes, because the FBS level of patient 556969 is really 120 mg/dL.
- B.
  
  No, because the actual FBS level of patient 556969 is 169 mg/dL.
- C.
  
  No, because the actual FBS level of patient 556969 is 127 mg/dL.
- D.
  
  No, because the actual FBS level of patient 556969 is 134 mg/dL.
13.

- B.
  
  8AM the day after tomorrow
- C.
  
  8AM in another time zone
- D.
