On a Processor Quality Control Chart (Form 1) record:
A. The facility name, processor ID, if applicable, film brand name, emulsion number from the QC box of film, and date month or days or week or years?

A

month and year

120
Q

To determine the control limits

A

Add and subtract 0.15 Optical Density (OD) to the MD average density.

Add and subtract 0.15 OD to the DD value.

Add and subtract 0.03 OD to the average Base plus Fog density.

120
Q

True or false. Changing the chemistry, as part of routine preventative processor maintenance is justification for re-establishing processor operating levels.

A

False it is not justification

120
Q

Re-establishment of operating levels and control limits should be done for the purpose of bringing an out of control processor into compliance.

A

False, should never be done for the purpose of bringing an out of control processor into compliance.

120
Q

True or false. The reason why a processor is out of control must be determined and the problem corrected.

A

True

120
Q

The regulations require that be performed each workday when radiographs are to be processed, before processing any patient films but after the processor warm-up.

A

processor quality control

120
Q

Equipment Required for daily processor quality control:

A
  • Sensitometer
  • Densitometer
  • Fresh Box of control film.
  • Form 1 Processor Quality Control Chart
  • Digital thermometer accurate to at least “ 0.5F
120
Q

in Maintain Processor Quality Control Charts for at least how many years?

A

one year

120
Q

In Daily Processor Quality Control, Actual sensitometric strips should be maintained for at least the

A

the current 6 weeks

120
Q

On Daily Processor Quality Control, CORRECTIVE ACTIONS: immediate action must be taken to correct any problems. Films must not be processed until processor is operating within limits set by the regulations. All corrective actions must be completed before patient films are taken, documented and records retained for a minimum of how many years?

A

2 years

120
Q

True or false. If the processor seldom has problems, do not discontinue the quality control program. The lack of problems indicates that the process is in control at the present time but does not predict the stability of the processor in the future.

A

True
