BupropionInsomnia, agitationLowers seizure threshold; avoid in eating disorders and seizure disorders
TCAs (amitriptyline)Anticholinergic effects, orthostasis, sedationOverdose is cardiotoxic; limit supply in clients at risk of suicide

NGN-style case and teaching

Safety assessment is the priority.

functions Clinical judgment case — new energy

A client started on sertraline 2 weeks ago for major depression is suddenly cheerful, more energetic, and gave away a favorite guitar. What should the nurse do first?

  1. Recognize cues: sudden improvement in mood or energy early in treatment plus giving away possessions.
  2. Analyze: these can be warning signs of a suicide plan.
  3. Act: ask directly about suicidal thoughts, plan, and means.
  4. Ensure safety per protocol and notify the provider.

Answer. Assess suicide risk directly by asking about thoughts, plan, and means, and keep the client safe per protocol.

  • Keep taking the medication; improvement takes weeks.
  • Do not stop suddenly; talk to the provider about tapering.
  • Avoid alcohol and check with the pharmacist before taking other drugs or supplements, including St. John's wort.
  • Report worsening mood, thoughts of self-harm, agitation, or fever with confusion.
