Which of the following terms describes a person responsible for representing another's interests, particularly in health care?

The term that describes a person responsible for representing another's interests, particularly in health care, is ombudsman. An ombudsman typically serves as an advocate for patients, addressing their concerns and ensuring their rights are respected within the healthcare system. This role is essential in advocating for patients who may feel overwhelmed or powerless when navigating medical services.

In contrast, the other terms refer to specific healthcare professionals with specialized training. An otolaryngologist is a physician specializing in the diagnosis and treatment of ear, nose, and throat disorders. An orthopedist focuses on the musculoskeletal system, including bones, joints, ligaments, and muscles. An occupational therapist assists patients in improving the skills needed for daily living and working due to injury, illness, or disability. While these professionals play important roles in healthcare, they do not have the specific duty of representing a person's interests in the context of health care advocacy as an ombudsman does.
