Key functions of primary care.

• A. Diagnosis, Treatment, Referral, Billing
• B. First contact, Continuity, Comprehensiveness, Coordination
• C. Research, Education, Advocacy, Policy
• D. Emergency care, Triage, Imaging, Prescriptions

Answer: (B)

The four main functions of primary care are first contact, continuity, comprehensiveness, and coordination. First contact means primary care serves as the entry point for health concerns, making care readily accessible when a new problem arises. Continuity refers to an ongoing relationship between a patient and a primary care clinician over time, which builds trust, deepens understanding of the patient’s history, and improves management of chronic conditions. Comprehensiveness captures the broad scope of care provided in primary care—from preventive services to acute treatment and chronic disease management—addressing a wide range of health needs in one setting. Coordination involves organizing care across the health system, including referrals to specialists and integration with community resources, so care is coherent and efficient.

This set best reflects what primary care aims to deliver: a reachable, long-term, wide-ranging, and well-integrated approach to health. The other options emphasize tasks like diagnosis, treatment, referral, and billing, which are common in many settings but don’t alone define primary care’s essential functions. The option listing research, education, advocacy, and policy highlights broader healthcare roles outside everyday clinical practice, and the one focusing on emergency care, triage, imaging, and prescriptions points to urgent or hospital-based care rather than ongoing primary care.
