Are risk free for neuroleptic malignant syndrome (NMS) Ans: ANS: C Rationale : Atypical antipsychotics produce less D2 blockade; thus movement disorders are less of a problem. No evidence suggests that the medication remains in the system longer nor that it actsmore quickly to reduce delusions. The atypicals are not risk free for NMS. 2.
