Question 2

Action

Answer 2

Bethanechol chloride is a cholinergic agent that acts by stimulating the release of acetylcholine at the nerve ending, thereby activating the parasympathetic nervous system. It significantly increases the tone of the detrusor urinae muscle, usually producing a contraction that can sufficiently initiate micturition and bladder emptying. It also modulates gastric motility, increases gastric tone and restores impaired rhythmic peristalsis.

Question 3

Teaching

Answer 3

Patient should avoid activities requiring coordination until drug effects are realized, as drug may cause light-headedness or dizziness.
Instruct patient to rise slowly from a sitting/supine position to help prevent dizziness.
This drug may cause syncope, flushing, diarrhea, stomach cramps, excessive tear production, miosis, or urinary urgency.
Patient should take drug at least 1 h before or 2 h after meals, as nausea and vomiting may occur if taken soon before or after eating.
Instruct patient to take a missed dose as soon as possible if it is less than 1 h late. If missed dose is more than 2 h past normal dosing time, then skip the missed dose.
