Ethnicity refers to a cultural group's shared social and cultural heritage. It is complex and not always clearly defined. Characteristics include common language, religion, traditions, and food preferences. Culture represents learned behaviors and influences how patients and nurses relate. It includes values, beliefs, and customs learned from family. Nurses must consider a patient's socialization, including extended family, community, and participation in cultural and religious practices and beliefs to provide appropriate care. Prejudice can negatively impact the care patients receive from nurses if present.
