The primary function of a subpoena is to require a person to appear in court to give testimony. A subpoena is a legal document that commands an individual to attend a legal proceeding, such as a trial or deposition, and provide evidence or testimony relevant to a case. This tool is often used in legal contexts to ensure that witnesses can be compelled to appear and provide their account of events, thereby supporting the pursuit of justice.

In this context, the other options do not reflect the purpose of a subpoena. Granting permission for the release of medical records relates to consent and privacy laws, which are governed by regulations such as HIPAA, and do not involve a subpoena. Providing patients with information about their rights pertains to informed consent and advocacy, not the legal compelling of testimony. Managing healthcare facility operations involves administrative functions that are unrelated to the legal obligations enforced by a subpoena.
