Final answer:
Hospital medical staff are indeed self-governing bodies responsible for peer-review activities, ensuring high standards in healthcare across various types of health institutions.
Step-by-step explanation:
The statement that a hospital's medical staff is a self-governing organization that typically has the responsibility for performing peer-review activities is true. In most healthcare institutions, be it a nonprofit health organization, a private hospital, or a governmental agency like Health and Social Services, the medical staff is organized to monitor the quality of care, review cases, and handle the credentials of new staff. The self-governance aspect allows medical professionals to regulate themselves to ensure standards and practices are maintained and to review the work of their peers critically. This is part and parcel of maintaining the quality of healthcare services and is a principle upheld in various healthcare systems.
