Which supervision model requires the physician to be physically present in the building?

• A. General supervision
• B. Direct supervision
• C. Retrospective supervision
• D. Collaborative relationship

Answer: (B)

Direct supervision requires the supervising physician to be physically present in the same building during the procedure. This arrangement ensures immediate, hands-on guidance and the ability to intervene right away if anything goes wrong or needs adjustment, which is especially important for learners and high-risk tasks. By contrast, general supervision allows the supervisor to be available but not necessarily in the same room or building, retrospective supervision involves review after the fact, and a collaborative relationship describes a professional partnership without a formal on-site requirement.
