What are the standard time and temperature parameters for achieving sterilization in an autoclave? ___________________?
Show answer Hide answer
Answer: D. 121°C 15 mts. x 15 lbs pr.
Explanation
Autoclave sterilization requires high temperature, adequate steam pressure, and sufficient exposure time. Standard parameters dictate heating to 121 degrees Celsius at fifteen pounds of pressure. Maintaining these conditions for a minimum of fifteen minutes ensures complete destruction of spores. Autoclaves utilize moist heat under pressure to penetrate and destroy resistant microbial endospores. Water boils at higher temperatures when placed under increased atmospheric pressure inside a sealed chamber. Biological indicators containing bacterial spores validate that autoclave cycles achieve true sterilization.
Hospitals and laboratories rely on strict adherence to these parameters to sterilize equipment safely. Inadequate temperature or time settings can result in unsterilized medical instruments and patient infections. Standardized sterilization cycles ensure safety and consistency across all biomedical facilities. Option A incorrectly specifies parameters associated with dry heat or different processing cycles. Option B incorrectly cites Fahrenheit units instead of Celsius for the required operating temperature. Option C specifies an inadequate time duration of fifteen seconds which fails to sterilize loads.
