Which of the following is located within the NIH?

The National Library of Medicine (NLM) is indeed located within the National Institutes of Health (NIH) in Bethesda, Maryland. As one of the largest biomedical libraries in the world, NLM provides access to a vast collection of medical literature, databases, and resources that support research and public health initiatives. Its integration within the NIH allows for collaboration with other institutes and centers focused on health, medicine, and biomedical research.

The other organizations mentioned, while critical to health and public safety, are not part of the NIH. The Centers for Disease Control and Prevention (CDC) operates under the Department of Health and Human Services and focuses on preventing disease and promoting public health. The Food and Drug Administration (FDA), also part of the Department of Health and Human Services, is responsible for regulating food and drug products to ensure safety and efficacy. The National Institute for Occupational Safety and Health (NIOSH) is a part of the CDC and focuses on ensuring safe and healthy working conditions. Each of these agencies has its own distinct mission and regulatory framework that is separate from the NIH.
