Which of the following is an example of a clinical contact surface?

  1. Floor

  2. Countertops

  3. Ceiling

  4. Window

The correct answer is: Countertops

Clinical contact surfaces are those surfaces that come into direct contact with patients or medical equipment during patient care, increasing the risk of spreading infections. While the floor, ceiling, and window are all surfaces in a clinical setting, they are not considered clinical contact surfaces as they generally do not come into direct contact with patients or medical equipment. Countertops, on the other hand, are used to hold and perform medical procedures or place medical equipment, making them high-touch surfaces that require regular cleaning and disinfection to prevent the spread of infections.
