A nurse is walking down the unit hall and sees a blood spill on the floor.
Which of the following agents should the nurse use to sanitize the floor?

Choice A rationale

Lowering a used mask below the chin to reuse it later is not safe as it can lead to contamination of the mask and facial area, increasing the risk of infection.

Choice B rationale

Removing the mask first before any other personal protective equipment (PPE) can lead to contamination and is not the recommended sequence for doffing PPE.

Choice C rationale

Discarding the mask only if it is wet and storing it for reuse is not safe. Masks should not be reused, as they can harbor infectious agents and increase the risk of contamination.

Choice D rationale

Untying the bottom ties first, then the top, and disposing of the mask without touching it ensures that the person removing the mask avoids contamination. This method adheres to proper doffing procedures and minimizes the risk of infection.

Choice A rationale

Limiting ambulation can increase the risk of complications such as deep vein thrombosis and does not necessarily reduce HAIs.

Choice B rationale

Encouraging the patient to turn, cough, and deep breathe every 2 hours helps prevent respiratory complications, improves lung function, and reduces the risk of pneumonia, a common HAI.

Choice C rationale

Keeping the room door closed does not prevent HAIs and might isolate the patient, reducing mobility and social interaction.

Choice D rationale

Regular monitoring of vital signs is essential but does not directly reduce the risk of HAIs. Other measures, like proper hygiene and mobilization, are more effective.
