Answer to Question 1

A
Diphenhydramine, trihexyphenidyl, benztropine, and other anticholinergic medications may be used
to treat dystonias, but because the client is drooling the nurse must assume swallowing is difficult, if
not impossible. Therefore oral medication is not an option. Medication should be administered
intramuscularly. In this case the option given is diphenhydramine.

Answer to Question 2

ANS: D
Muscarinic receptor blockade includes atropinelike side effects such as dry mouth, blurred vision,
and constipation. Option A: Gynecomastia is associated with decreased prolactin levels. Option B:
Movement defects are associated with dopamine blockade. Option C: Orthostatic hypotension is
associated with a1 antagonism.
