Question

which anticholinergic effect does the nurse monitor in a patient taking promethazine hydrochloride?
diarrhea
paresthesias
blurred vision
increased salivation

Explanation:

Anticholinergic effects block the action of acetylcholine. Promethazine hydrochloride can cause blurred vision as an anticholinergic side - effect. Diarrhea is not an anticholinergic effect (anticholinergics tend to cause constipation). Paresthesias are not related to anticholinergic action. Anticholinergics decrease, not increase, salivation.

Answer:

Blurred vision
