Infection Control · single question

Before exposing a radiograph on an HIV-positive patient, the appropriate infection-control approach for the sensor/film is:

  1. No barrier is required for this patient
  2. Use a barrier (bag) and then disinfect by double-wiping ('one bag, double wipe')
  3. Heat-sterilize the digital sensor in an autoclave
  4. Cold-sterilize the sensor by immersion only
Show answer and explanation

Correct answer: B. Use a barrier (bag) and then disinfect by double-wiping ('one bag, double wipe')

  • A. Standard precautions apply to EVERY patient; barriers are always used.
  • B. Correct. Bag the sensor as a barrier, then disinfect with the double-wipe technique (clean, then disinfect).
  • C. Autoclaving destroys most digital sensors.
  • D. Immersion can damage sensors and is not the recommended method.

Note: Standard (universal) precautions mean the protocol is identical for HIV-positive and all other patients.
