When obtaining an adolescent's health history, which intervention is most important for the nurse to implement?

Choice A reason: Evaluating vital signs and lab findings is important, but it is not the most critical intervention when obtaining an adolescent’s health history. These are objective measures, but they do not encourage open communication. Choice B reason: Asking the parents to leave the room is the most important intervention. Adolescents are more likely to disclose sensitive information such as sexual activity, substance use, or mental health concerns when privacy is ensured. This builds trust and allows for accurate assessment. Choice C reason: Assessing for illicit drug use is important, but it should be done after establishing rapport and ensuring privacy. Without privacy, the adolescent may withhold information. Choice D reason: Obtaining a smoking history is relevant, but prioritizing it first does not address the broader need for confidentiality and trust. Smoking history can be obtained later in the interview.
