What do spills refer to in a healthcare context?

In a healthcare context, spills refer specifically to the unintentional release of liquids, which can create hazards in the environment. When liquids, such as medications, cleaning solutions, or bodily fluids, are spilled, they can pose a risk for slips, falls, and contamination of surfaces or equipment. This makes immediate attention and proper cleanup essential to maintain a safe and hygienic environment for both patients and healthcare staff.

The other options represent different actions or processes that are important in a healthcare setting but do not align with the definition of spills. Regularly cleaning surfaces is an important aspect of infection control, and collecting waste materials and refilling fluids are necessary tasks in patient care, yet these do not indicate the unintentional nature of liquid release that is encapsulated by the term "spills."
