The nurse is administering haloperidol (Haldol) to a client experiencing delusions and hallucina-tions associated with schizophrenia. The nurse can expect symptom abatement as a result of the drug's action to:
1. Reduce the number of brain cells that crave dopamine
2. Block dopamine receptors, making dopamine less available
3. Enhance dopamine receptors, making more dopamine available
4. Cause increased cellular production of dopamine
ANS: 2
Excess dopamine is responsible for symptoms of psychosis such as delusions and hallucinations. Blocking dopamine receptors will result in reduction of primary symptoms. The other options do not reflect the action of typical antipsychotic medications.
