After 7 hours in restraints and a total of 30-mg haloperidol in divided doses, a client complains of stiffness in his neck and his tongue "pulling to one side." These extrapyramidal symptoms (EPS) will most likely be relieved by the administration of:
A. Lorazepam (Ativan)
B. Benztropine (Cogentin)
C. Thiothixene (Navane)
D. Flurazepan (Dalmane)
Correct Answer: B
Explanation/Reference:
Explanation:
(A) Lorazepam is an antianxiety agent that produces muscle relaxation and inhibits cortical and limbic arousal. It has no action in the basal ganglia of the brain. (B) Benztropine acts to reduce EPS by blocking excess CNS cholinergic activity associated with dopamine deficiency in the basal ganglia by displacing acetylcholine at the receptor site. (C) Thiothixene is an antipsychotic known to block dopamine in the limbic system, thereby causing EPS. (D)Flurazepan is a hypnotic that acts in the limbic system, thalamus, and hypothalamus of the CNS to produce sleep. It has no known action in the vasal ganglia.
