Infection Control · single question

When using a digital sensor on an HIV-positive patient, what is the CORRECT infection control protocol?

  1. Standard barriers only — HIV status requires no additional precautions
  2. Sterilize in autoclave between uses
  3. Double barrier plus disinfecting wipe after removal of outer barrier
  4. Single barrier only (plastic wrap)
Show answer and explanation

Correct answer: C. Double barrier plus disinfecting wipe after removal of outer barrier

  • A. Incorrect. Universal precautions require barrier protection for all patients. Standard barriers must include the double-barrier protocol for sensors.
  • B. Incorrect. Digital sensors contain electronic components and CANNOT be autoclaved.
  • C. Correct. Recommended protocol: DOUBLE BARRIER (inner sensor sheath + outer plastic sleeve). After use, carefully remove outer barrier, then wipe sensor with an approved disinfecting wipe. This applies to ALL patients under universal precautions — HIV status does not change the protocol beyond standard precautions.
  • D. Incorrect. A single barrier is insufficient for digital sensors.
