Answer to Question 1

ANS: B
Dilating the eye before eye examinations allows for better visualization of the interior of the globe. Anticholinergic drugs may produce drying of tears in the eye as an adverse effect of use. Obstruction of the canal of Schlemm results in glaucoma. Paralysis of the ciliary muscle is cycloplegia.

Answer to Question 2

ANS: B, D, F
These agents inhibit the metabolism of tolterodine, darifenacin, and solifenacin. Warfarin, phenytoin, and heparin are not influenced by these drugs.
