On an International Service Learning trip to Costa Rica, I traveled with other students and opened clinics in Heredia and Alajuela, provinces of Costa Rica. These clinics were free and for the local underserved population of the provinces. This trip worked closely with Costa Rican doctors. As a student on this trip, the others and I took the place of nurses, and performed patient interviews, collected medical history, took vital signs such as blood pressure, and performed physical exams that included auscultation of the heart and lungs and patient specific tests for diabetes, malnutrition, and parasites. This trip honed critical-thinking skills, communication skills across the language barrier, and working with others in a medical team.
