neuroleptic malignant syndrome (NMS) for help lower the
... [Show More] dopamine blockade? Correct Answer:
Bromocriptine (Paroled) is the recommended direct acting dopamine receptor agonist to help
decrease the dopamine blockade. Dan Rolene (Atrium) is a muscle relaxant. Benzotropine (Cogentin)
and Trihexyphenidyl (Arcane) are anticholinergic medications used for extrapyramidal side effects

actions? Correct Answer: Institute twice-weekly complete blood count with differentials and monitor
closely.
The recommended cut-points for discontinuation of clozapine are WBC of 2,000 to 3,000 or
granulocytes of 1,000 to 1,500 for agranulocytosis and severely compromised immune system. At a
WBC of 4,000, the recommendation is to closely monitor CBC with differential twice a week while
patient may continue clozapine in the absence of any other signs or symptoms.

Which of the following statements reflect the current understanding of dopamine (DA) pathways and
clinical symptoms in schizophrenia? Correct Answer: A) Negative symptoms are related to DA deficit
in the cerebral cortex; positive symptoms are related to DA excess in the nucleus accumbens and
mesolimbic system.
Negative symptoms & cognitive impairment are thought to be related to hypoactivity of the
mesocortical dopiminergic tract, which by its association with the prefrontal cortex and neocortex
contributes to motivation, planning, sequencing of behaviors in time, attention, and social behavior.
Positive symptoms (hallucination and delusions) are thought to be caused by dopamine hyperactivity [Show Less]
