Psychotic Disorders no. 4080

QUESTION: A dopamine receptor agonist such as bromocriptine (Parlodel) relieves muscle rigidity caused by antipsychotic medication by:

✘O a.) blocking dopamine receptors in the central nervous system (CNS).
✘O b.) blocking acetylcholine in the CNS.
✘O c.) activating norepinephrine in the CNS.
✓O d.) activating dopamine receptors in the CNS.

RATIONALE

RATIONALE: Extrapyramidal effects and the muscle rigidity induced by antipsychotic medications are caused by a low level of dopamine. Dopamine receptor agonists stimulate dopamine receptors and thereby reduce rigidity. They don't affect norepinephrine or acetylcholine.
