Increasing serotoneric activity in the amygdala diminishes symptoms of anxiety. D. Decreasing NE in the LC diminishes symptoms of anxiety. - Answer ️️ -A, C & D are all correct so the answer is B As a PMHNP, you know anti-psychotic meds have side effects.

Sedation We know that Dry mouth, drowsiness, dizziness, restlessness, wt gain, constipation & N/V are all SE but, Tardive Dyskinesia does not start for 1-2 years. My answer - B. *Tardive Dyskinesia (TD*) ** long standing blockage of DA2 in nigrostriatal pathway leads to TD Which Serotonin receptor antagonism makes an antipsychotic "atypical"? A. 5HT1A B. 5HT3A C. 5HT4A D. 5HT2A - Answer ️️ -Atypical antipsychotic drugs such as clozapine, olanzapine, quetiapine, risperidone, sertindole, and ziprasidone are potent 5-HT2a receptor antagonists and relatively weaker dopamine D2 antagonists. Commonly Prescribed Typical and Atypical Antipsychotic Medications Typical antipsychotics include: Haldol (haloperidol); Loxitane (loxapine); Mellaril (thioridazine); Geodon (ziprasidone) Moban (molindone); Seroquel (quetiapine) Navane (thiothixene); Zyprexa (olanzapine) Prolixin (fluphenazine); Serentil (mesoridazine) Stelazine (trifluoperazine); Trilafon (perphenazine) Thorazine (chlorpromazine) Atypical antipsychotics include: Abilify (aripiprazole); Clozaril (clozapine) Geodon (ziprasidone); Seroquel (quetiapine) Zyprexa (olanzapine) Which medication inhibits both dopamine and norepinephrine? A. Venlafaxine (effexor) B. Duloxetine (Cymbalta) C. Buproprion (Wellbutrin) D. Imipramine (Tofranil) - Answer ️️ -C. Buproprion (Wellbutrin) Bupropion inhibits the presynaptic reuptake of both dopamine (DA) and noradrenaline (NA), leading to increased levels of both of these neurotransmitters in the synaptic cleft Current understanding of Dopamine (DA) pathways &
