A patient who started risperidone reports breast enlargement and milk discharge. Which adverse effect should the nurse suspect?

Correct answer: A. Hyperprolactinaemia

  • A. Hyperprolactinaemia
  • B. Acute dystonia
  • C. Agranulocytosis
  • D. Tardive dyskinesia

Explanation

Risperidone can increase prolactin by blocking dopamine pathways, leading to galactorrhoea, breast changes and menstrual or sexual problems. Acute dystonia causes sudden muscle spasms, agranulocytosis causes severe infection risk, and tardive dyskinesia causes late repetitive movements.
