Step-by-step explanation:
If you find clean folded linen on the floor in a patient's room, the first step you should take is to place the linen in the laundry hamper. This is important for maintaining hygiene and preventing the spread of germs. Returning the linen to the linen chart or using it to change the patient's bed linen would not be appropriate as it could introduce contaminants into the patient's environment. It's also important to inform the nurse about the situation so that they are aware and can take any necessary action.
