Which topic should the nurse include in planning a primary prevention class for adolescents?

The correct topic that the nurse should include in planning a primary prevention class for adolescents is suicide risks and prevention. Adolescents are particularly vulnerable to mental health issues, including suicidal ideation. Educating them about suicide risks and prevention strategies is crucial for early intervention and support. Choices A, B, and D are important topics, but when considering primary prevention for adolescents, addressing suicide risks and prevention takes precedence due to its immediate life-saving implications.
