Family Medicine
Exam Materials
Course Introduction
Family Medicine is a medical specialty devoted to comprehensive healthcare for people of all ages, focusing on the holistic treatment of individuals and families within the context of their communities. This course emphasizes preventive care, diagnosis, and management of common acute and chronic illnesses across all life stages. Students will explore concepts such as continuity of care, patient-centered communication, health promotion, and coordination with other healthcare professionals. Through a combination of lectures, case discussions, and clinical experiences, the course prepares future practitioners to deliver evidence-based, compassionate, and culturally competent care in a primary care setting.
