X-ray sensor/digital sensor barrier technique — what is the correct infection control protocol?
Show answer and explanation
Correct answer: D. Double plastic barrier, single wipe
- A. Single barrier with double wipe does not provide adequate protection for a digital sensor.
- B. Single barrier alone is insufficient — risk of contamination through a single barrier.
- C. Digital sensors cannot be immersed in liquid disinfectants — this would damage the electronics.
- D. Correct. For digital X-ray sensors: use a DOUBLE plastic barrier (two layers of plastic wrapping), and perform a SINGLE wipe of the sensor surface with an appropriate disinfectant between patients. The double barrier protects the expensive sensor from saliva contamination while the wipe ensures surface disinfection.
