#1
What is the recommended method for sterilizing surgical instruments?
Autoclaving at high pressure and temperature
ExplanationAutoclaving ensures thorough sterilization by combining high pressure and temperature.
#2
Which of the following is NOT a critical step in instrument cleaning?
Rinsing instruments with cold water
ExplanationCold water rinsing is not effective in removing debris and contaminants from instruments.
#3
What is the recommended temperature for an autoclave to achieve sterilization?
121°C (250°F)
ExplanationThis temperature ensures efficient sterilization in an autoclave.
#4
Which of the following is NOT a method for sterilizing surgical instruments?
Boiling in cold water
ExplanationBoiling in cold water is not sufficient for sterilizing instruments effectively.
#5
What is the primary purpose of packaging instruments after sterilization?
To maintain sterility until use
