A patient begins therapy with a first generation antipsychotic medication. What teaching should a nurse provide related to the drug's strong dopaminergic effect?

A) Chew sugarless gum.
B) Increase dietary fiber.
C) Arise slowly from bed.
D) Report muscle stiffness.

First generation antipsychotic medications block dopamine receptors in both the limbic system and basal ganglia. Dystonia is likely to occur early in the course of treatment and is often heralded by sensations of muscle stiffness. Early intervention with an antiparkinsonian medication can increase the patient's comfort and prevent dystonic reactions. The incorrect responses apply to potential anticholinergic effects of first generation antipsychotic medications.
