A nurse aide notices a resident's room floor is wet from a recently mopped area. What is the priority action to prevent a fall?

  1. APlace a 'wet floor' caution sign and block access until dry
  2. BLeave the floor as is since it will dry quickly
  3. CMop the floor again to dry it faster
  4. DTell the resident verbally to be careful when walking
Show answer & explanation

Correct answer: A. Place a 'wet floor' caution sign and block access until dry

Placing a visible wet floor sign and restricting access until the floor is dry is the standard safety measure to prevent slips and falls. A verbal warning alone or leaving the area unmarked does not adequately protect residents, especially those with cognitive or mobility impairments.

Why the other options are wrong

  • B. Leaving a wet floor unmarked risks a slip-and-fall injury.
  • C. Mopping again does not dry the floor and adds more moisture.
  • D. Verbal warnings may be forgotten or not heard by all residents.

Wet Floor Hazard Prevention

A fall-prevention practice requiring visible warning signage and restricted access whenever floors are wet to reduce slip risk.

  • Wet floor signs must be clearly visible
  • Block access if possible until floor dries
  • Applies to spills, mopping, and weather tracked-in water

Memory trick: See wet, set the sign — silence isn't a safety plan.
