A patient taking medication for mental illness develops restlessness and an uncontrollable need to be in motion. A nurse can correctly analyze that these symptoms are related to which drug action?
a. Anticholinergic effects
b. Dopamine-blocking effects
c. Endocrine-stimulating effects
d. Ability to stimulate spinal nerves
ANS: B
Medications that block dopamine often produce disturbances of movement such as akathisia because dopamine affects neurons involved in both the thought processes and movement regulation. Anticholinergic effects include dry mouth, blurred vision, urinary retention, and constipation. Akathisia is not caused by endocrine stimulation or spinal nerve stimulation.
