Which professional diagnoses, treats, and prevents disease or disorders and may specialize?

• A. Doctor of Medicine (MD)
• B. EMT
• C. Doctor of Chiropractic (DC)
• D. Psychiatrists

Answer: (A)

The main idea is identifying the professional who can diagnose, treat, and prevent disease or disorders across the body and may specialize. A Doctor of Medicine fits this role because MDs are trained as physicians to evaluate patients, make diagnoses, develop and carry out treatment plans, and emphasize preventive care through screening and health maintenance. They complete medical school, then residency, and can pursue numerous specialties such as internal medicine, surgery, pediatrics, or cardiology, which reflects the “may specialize” part. In contrast, an EMT provides emergency care without diagnosing diseases or managing ongoing treatment; a chiropractor focuses on musculoskeletal issues and spinal care rather than broad disease prevention; psychiatrists are physicians who specialize in mental health, diagnosing and treating mental disorders, but their scope is specific to that area rather than the full range of medical diseases and disorders.
