An example of an ancillary service would include?

• A. Radiology.
• B. Environmental services.
• C. Nutrition.
• D. Security.

Answer: (A)

Ancillary services are hospital departments that provide specialized clinical support to patient care beyond the core treatment by physicians. Radiology fits this role because imaging studies like X-rays, CTs, and MRIs supply crucial diagnostic information that guides diagnoses and treatment plans. While environmental services, nutrition, and security are essential support functions that keep the hospital running, they are usually categorized as facility or non-clinical support rather than ancillary clinical services. So radiology is the classic example of an ancillary service.
