Which aspects are shaped by widely used benchmarks from the Guide for the Care and Use of Laboratory Animals?

• A. Lighting schedules only
• B. Financial budgeting
• C. Staffing recruitment policies
• D. Housing, husbandry, veterinary care, and procedures

Answer: (D)

The main idea is how established benchmarks guide what facilities must provide for animal care in research. The widely used benchmarks from the Guide set minimum standards that shape housing, husbandry, veterinary care, and procedures. This means the environment in which animals live, the daily care they receive, how their health is monitored, and the methods used in experiments are all defined to meet welfare and scientific quality goals. Lighting schedules fit within housing standards, but the scope is broader, covering the full range of care and use aspects, not just one element. Administrative items like financial budgeting or staffing policies matter for program operation, but they aren’t the primary focus of these care-and-use benchmarks.
