Answer to Question 1

ANS: D
The inhibition of cholinergic activity (anticholinergic effects) causes pupil dilation, which increases intraocular pressure in patients with glaucoma. In patients with closed-angle glaucoma, anticholinergic medications can precipitate an acute attack. Anticholinergic agents may produce increased heart rate but not hypertension. Anticholinergic agents do not affect infections or diabetes.

Answer to Question 2

ANS: C
Anticholinergic agents inhibit the action of acetylcholine in the parasympathetic nervous system. These drugs occupy receptor sites at the parasympathetic nerve endings, preventing the action of acetylcholine. Inhibition of acetylcholine facilitates stimulation of the dopaminergic receptors, which relieves the symptoms associated with Parkinson's disease. Anticholinergic agents cause urinary retention, increase intraocular pressure, and increase the heart rate.
