What principle makes an autoclave effective for sterilising veterinary surgical instruments?
Correct answer: C. Saturated steam under pressure
- A. Dry heat at atmospheric pressure
- B. Ultraviolet light exposure
- C. Saturated steam under pressure
- D. Chemical disinfection in alcohol
Explanation
An autoclave uses saturated steam under pressure to transfer heat efficiently and destroy microorganisms, including bacterial spores. Boiling and alcohol disinfection may reduce contamination but do not provide the same reliable sterilisation.
