A 46-year-old female client has been on antipsychotic neuroleptic medication for the past three days. She has had a decrease in psychotic behavior and appears to be responding well to the medication. On the fourth day, the client's blood pressure increases, she becomes pale and febrile, and demonstrates muscular rigidity. Which action will the nurse initiate?
Correct Answer: B
Rationale: These symptoms are indicative of neuroleptic malignant syndrome (NMS), which is a severe and life-threatening reaction to neuroleptic drugs. The major symptoms include fever, rigidity, autonomic instability, and encephalopathy. Respiratory failure, cardiovascular collapse, arrhythmias, and/or renal failure can lead to death. This is an emergency situation requiring immediate critical care, thus the correct action is to transfer the client to the ICU (B). Seizure precautions (A) are not relevant in this scenario. Merely describing the symptoms to the charge nurse and documenting them (C) or taking no action assuming these are common side effects (D) fail to address the critical nature of the situation and the urgency of immediate intervention.
