Answer to Question 1

C
Feedback:
Isosorbide dinitrate's effective dose is usually determined by increasing the dose until the patient experiences a headache, which will indicate maximum tolerable dose. The development of nausea does not indicate maximum tolerable dose. The patient should not see halos around lights with isosorbide dinitrate. The patient will not have an increase in heart rate.

Answer to Question 2

B
Feedback:
Cholinergic drugs are used to treat atony of the smooth muscle of the gastrointestinal tract and urinary systems. Anticholinergic agents will decrease muscle strength. Muscle relaxants will decrease muscle strength. Selective serotonin reuptake inhibitors are not used for atony of the smooth muscle of the gastrointestinal tract.
