Which statement best describes the autoclave's role in infection control?

• A. To sterilize equipment and instruments by using steam under pressure.
• B. To disinfect surfaces with antiseptic wipes.
• C. To store sterile supplies in a dry cabinet.
• D. To heat patient specimens for preservation.

Answer: (A)

Sterilization using steam under pressure is what the autoclave does in infection control: it destroys all forms of microbial life, including spores, by exposing instruments to high-temperature, high-humidity steam under pressure. This makes instruments completely sterile for patient use. This differs from disinfection, which lowers the microbial load but may not kill spores and is usually done with chemical agents on surfaces. Autoclaving isn’t about storing supplies—storage needs dry, clean conditions to maintain sterility—and it isn’t used to heat specimens for preservation, which uses other methods like fixation or cooling. Typical cycles involve steam at about 121°C under pressure (roughly 15 psi) for a defined time to ensure sterility.
