Answer to Question 1

D
Feedback:
Administer bethanechol and all oral forms of direct-acting cholinergic agonists on an empty stomach to decrease nausea and vomiting. The other options do not correctly explain the rationale for administering bethanechol on an empty stomach.

Answer to Question 2

A
Feedback:
Preload is the amount of blood brought back to the heart to be pumped through the body. Vasodilation and shock will reduce preload because the pressure in the system is reduced, pushing less fluid through the vessels.
