A patient taking haloperidol has a temperature of 39.5°C, severe muscle rigidity, confusion, and an increasing pulse rate. Which action should the nurse take first?
Correct answer: B. Stop the antipsychotic and notify the prescriber urgently
- A. Give the next dose with food to reduce stomach upset
- B. Stop the antipsychotic and notify the prescriber urgently
- C. Encourage ambulation to reduce the muscle stiffness
- D. Offer reassurance and place the patient in group therapy
Explanation
The combination of high fever, severe rigidity, altered mental status, and autonomic changes suggests neuroleptic malignant syndrome. The antipsychotic must be withheld and urgent medical treatment started because the condition can cause renal failure and death. This is a safety and circulation priority, not a routine side effect.
