The correct answer is d: must comply with the conditions of participation.
The Joint Commission is an independent, not-for-profit organization that accredits and certifies healthcare organizations in the United States. Accreditation by the Joint Commission means that a hospital has met certain standards for quality and safety, and must comply with the conditions of participation set by the Joint Commission. Accreditation does not automatically meet licensure or certification requirements, although it may be a requirement for some types of licensure or certification. Hospitals that meet certain additional criteria may also receive the designation of "magnet hospital" from the American Nurses Credentialing Center. This designation is recognized as a marker of excellence in nursing care.
