Which healthcare professional is primarily responsible for diagnosing diseases?

• A. Medical assistant
• B. Physician
• C. Health information technician
• D. Physical therapist

Answer: (B)

Diagnosing diseases requires extensive medical training to recognize patterns of symptoms, interpret tests, and determine a medical condition. Physicians are specifically trained through medical school, residency, and board certification to make these diagnoses and then develop treatment plans. Medical assistants help with administrative tasks and basic clinical tasks under supervision; they do not establish medical diagnoses. Health information technicians manage records and coding, supporting data accuracy but not diagnosing conditions. Physical therapists evaluate movement and functional impairments and plan rehabilitation, but they do not typically assign disease diagnoses. So, the professional primarily responsible for diagnosing diseases is the physician.
