Deviance is defined as behavior that violates social norms and causes disapproval or condemnation from others. It can suck people into deviant lifestyles from which it is difficult to escape due to social stigma. Deviance ranges from admired or odd behavior to more serious bad behavior and includes examples such as homosexuality, drug addiction, teenage pregnancy, prostitution, and mental illness. Understanding cultural diversity is important for nurses to effectively communicate with clients from different backgrounds.
