A heat-sensitive respiratory endoscope has been cleaned and requires processing before reuse. Which method is most appropriate?
Correct answer: B. High-level disinfection
- A. Low-level surface disinfection
- B. High-level disinfection
- C. Dry dusting with a sterile cloth
- D. Rinsing with ordinary tap water
Explanation
A respiratory endoscope contacts mucous membranes and is a semicritical item, so it requires high-level disinfection after thorough cleaning. Low-level disinfection and rinsing alone do not reliably remove the required range of microorganisms.

About Infection Prevention and Asepsis
Asepsis covers the chain of infection, hand hygiene, personal protective equipment, standard and transmission-based precautions, sterilisation, disinfection and safe waste disposal. The key distinction is between medical asepsis, which reduces microorganisms, and surgical asepsis, which maintains a sterile field during invasive procedures.
