What structural feature can help prevent splash contamination in living areas?

Avoiding fountains in resident care areas is vital for infection prevention because water features can be sources of splash contamination. Fountains, even those designed for aesthetic purposes, can disperse water droplets into the air, potentially carrying pathogens. These droplets can settle on surfaces, increasing the risk of infection transmission among residents and staff.

Infection control in nursing homes emphasizes minimizing any factors that could contribute to contamination in shared or living areas. By eliminating fountains, the risk of splashing and subsequent contamination is significantly reduced, leading to a safer environment for residents, particularly those who may have compromised immune systems.

The other options may not directly address the risk of splash contamination or could introduce other issues that may not be conducive to infection control.
