How often should a tonometer tip be sterilized?

  1. After every use

  2. Before every use

  3. Once a day

  4. Once a week

The correct answer is: Before every use

A Sterilizing the tonometer tip after every use would require frequent sterilization which could potentially damage the equipment or degrade its accuracy. C: Sterilizing the tonometer tip once a day may not be sufficient to prevent the spread of bacteria and other pathogens. D: Sterilizing the tonometer tip once a week may be too infrequent to effectively prevent the transmission of infections between patients. It is recommended to sterilize the tonometer tip before every use to ensure proper hygiene and safety for both the patient and the equipment.
