A school nurse is planning a presentation about identifying potential warning signs of suicide for high school students. Which of the following examples of behaviors should the nurse include in the teaching?

Choice A reason: Planning to attend a high school dance indicates social engagement, not a suicide warning sign. Suicidal ideation is associated with withdrawal, hopelessness, or mood instability, not positive social activities, making this choice incorrect for inclusion in the presentation. Choice B reason: Extreme mood swings are a key warning sign of suicide risk, reflecting emotional instability linked to depression or bipolar disorder. Rapid shifts in mood can indicate underlying psychological distress, increasing suicidal ideation, making this a critical behavior to include. Choice C reason: Seeking a tutor for academic help shows proactive problem-solving, not a suicide warning sign. It suggests motivation to improve, contrasting with hopelessness or withdrawal associated with suicide risk, making this choice incorrect for the presentation. Choice D reason: Volunteering at a homeless shelter indicates altruism and social engagement, not a suicide warning sign. Suicidal individuals often exhibit isolation or lack of purpose, making this positive behavior irrelevant for inclusion in the teaching.
