Answer to Question 1

d

Answer to Question 2

A
Muscarinic agonists are indicated to treat a patient with urinary retention.
Muscarinic agonists act on the heart to cause bradycardia, therefore they would not be indicated for a patient with a heart rate of 60/minute.
The use of a muscarinic agonist is contraindicated for patients with intestinal obstruction and for those recovering from recent surgery of the bowel.
Muscarinic agonists cause hypotension, therefore they would not be indicated for a patient with orthostatic hypotension.
