What document does an office manager receive to appear in court with a patient's medical record?

The correct choice is a subpoena duces tecum, a legal document that commands an individual to appear in court with specific documents or records—in this case, a patient’s medical record. This type of subpoena is important in legal situations where the information contained within medical records is needed for evidence.

The office manager would receive this document to ensure compliance with the request to provide physical evidence in court while remaining bound by confidentiality laws and patient rights. This is crucial in legal proceedings, particularly in cases involving patient care or outcomes, where medical records can provide essential context.

Other options do hold relevance in medical and legal contexts but do not serve the purpose of authorizing an office manager to present medical records in court. A durable power of attorney relates to the authority granted to another person to make decisions on behalf of a patient but does not pertain to court proceedings requiring the production of documents. A living will outlines a patient's wishes regarding end-of-life care but does not involve the legal summon of records. Informed consent is a document that ensures a patient is educated about the treatment they are receiving; it is also not a court document regarding medical records.
