Show answer & explanation

Correct answer: B. Remove all visible debris and hair from the surface.

Before disinfection, it is crucial to remove all visible dirt, debris, and hair from the surface. Organic matter can inactivate disinfectants, making them less effective. This pre-cleaning step ensures the disinfectant can work properly.

Why the other options are wrong

  • A. Spraying disinfectant on a dirty surface will be less effective as organic matter can interfere with its action.
  • C. Antiseptics are for skin, not for disinfecting inanimate surfaces.
  • D. Wiping with a clean cloth might remove some debris, but the primary first step is the active removal of all visible contaminants.

The essential step of physically removing all visible dirt, debris, and organic matter from a surface or item before applying a disinfectant.

  • Organic matter can inactivate disinfectants.
  • Ensures disinfectant efficacy.
