This document discusses genetics and its application in nursing. It defines genetics as the study of heredity and variation in traits from one generation to the next. Genetic nurses perform risk assessments and educate families about genetic conditions. Some key applications of genetics in nursing include genetic testing and counseling, newborn screening to prevent conditions like PKU, and managing care for patients with genetic disorders. The impact on families can include social stigma, discrimination, lowered self-esteem, stress, and lack of opportunities for those with physical or mental health issues resulting from genetic conditions.
