Which of the following can be a primary care physician (PCP)?

• A. Family physician
• B. Pediatrician
• C. Internist
• D. All of these are correct.

Answer: (D)

Being a primary care physician means serving as the first contact for patients, providing ongoing, comprehensive care, and coordinating other medical services as needed. Family medicine, pediatrics, and internal medicine are all specialties trained to fill that role for different patient groups. A family physician treats people of all ages, addressing preventive care, acute illnesses, and chronic conditions in a continuous care relationship. A pediatrician focuses on children from infancy through adolescence, handling vaccines, growth and development, common childhood illnesses, and family health guidance. An internist typically cares for adults, managing preventive care and multiple chronic conditions, often serving as the ongoing PCP for adult patients. Since each specialty can function as the main source of care and coordinate referrals and treatments, all three can be primary care physicians.
