What best describes the required composition of a 5-member IACUC?

A 5-member IACUC (Institutional Animal Care and Use Committee) must include a specific composition as mandated by the Animal Welfare Act and associated regulations to ensure a balance of perspectives. The correct answer describes this composition accurately as it includes a veterinarian, a scientist, a nonscientist, and a public member not affiliated with the institution.

Including a veterinarian ensures that there is expertise in the medical and welfare aspects of the animals involved in research. The scientist brings knowledge about the research processes and methodologies, while the nonscientist provides a broader perspective that includes ethical considerations and public concerns. The public member, who is not affiliated with the institution, serves to represent community interests and ensure that the views of individuals outside of the scientific community are considered in decision-making.

This diverse composition is essential for promoting ethical oversight and welfare of animals used in research, as it allows for a well-rounded review of protocols and a thorough assessment of the impact of research activities on both animal welfare and community values. Other combinations do not fulfill the regulatory requirement, either lacking one of the necessary perspectives or not meeting the requirement for a member from the public who is not affiliated with the institution.
