This item hinges on understanding facilities that offer a mix of medical and everyday support for a limited stay. A short-term care facility is defined as a place that provides both clinical services (medical, nursing, rehabilitation) and nonmedical assistance (daily living support) for a temporary period, typically after hospitalization or surgery, with the goal of returning the person home or to another setting soon. It’s the temporary nature and the combination of medical and nonmedical services that set it apart from longer-term care options. The other options aren’t about facilities: a soft wall system is a temporary barrier for containment, a vector is a disease-carrying organism, and walk-off mats are entryway cleaning mats.

Engineering controls are about physically changing the workplace to reduce exposure. They act at the source or in the environment to prevent contaminants from reaching workers, such as installing ventilation to dilute airborne hazards, using sealed containment, or enclosing the process with a biosafety cabinet. Work practice controls, by contrast, are about how tasks are performed to minimize exposure. They rely on procedural actions, training, and proper handling techniques rather than altering the environment itself. Examples include following specific safe-handling procedures and performing tasks in a manner that reduces risk. So the option describes engineering controls as physically modifying the environment to contain contaminants, which is exactly the distinction: engineering controls change the surroundings to lower exposure, while work practice controls SAMPLEdepend on how people perform the work. The other statements either describe administrative procedures, claim irrelevance, or equate PPE with administrative controls, none of which capture the fundamental difference.

The Safety Data Sheet (SDS) is the official document provided by the manufacturer that lists the hazards, safe handling, and emergency information for a chemical product. It gives you the hazard classification, ingredients, first-aid measures, personal protective equipment recommendations, spill response, storage, and disposal guidance. In infection control and risk assessment, the SDS is the primary reference for understanding chemical hazards in cleaners, disinfectants, and solvents and for determining appropriate controls and precautions. The other terms aren’t the standardized name for this document; historically the term MSDS was used, but the current standard is SDS.

Air sampling is the process of collecting air samples and analyzing them to measure contaminant concentrations in the workplace air. This approach lets you assess exposure levels, compare them to allowed limits, and determine whether current controls are effective or if additional measures are needed. A vector refers to an organism that transmits disease, not a sampling method. Abatement is about reducing or eliminating hazards, not measuring them. Acute health effects describe immediate health responses, not the act of collecting and analyzing air contaminants.
