What is the primary function of an expert witness in medical-legal cases?

Establishes the standard of care for the profession. A medical expert must testify. The trial will rely on the records. The patient's testimony is decisive.

Correct Answer:

Establishes the standard of care for the profession.

Explanation:

The essential job of an expert witness in medical-legal cases is to establish the standard of care for the profession. The court relies on the expert to describe what a reasonably competent practitioner would have done in similar circumstances, using the practitioner’s training, customary practices, and accepted guidelines. This standard serves as the benchmark to judge whether the clinician’s actions were negligent and whether any breach caused harm. While trial records and the patient’s testimony help build the factual picture—showing what happened and what the patient experienced—they do not define the professional duty itself.
