Answer to Question 1

ANS: C
The autonomic nervous system can be subdivided into alpha- and beta-adrenergic receptors. Nicotine and muscarine are specific agonists of one type of cholinergic receptor. Afferent and efferent are sensory and motor nerves. An agonist is a molecule that activates a receptor by reproducing the effect of the neurotransmitter. An antagonist acts against and blocks a function.

Answer to Question 2

ANS: A
Beta-adrenergic blocking agents cause vasodilation and decreased heart rate, resulting in lowering of the blood pressure. A premedication assessment is to take baseline heart rate and blood pressure. Fluid retention may occur as a serious adverse effect but is not the most important assessment prior to the administration of a beta-adrenergic blocking agent. Mental status and urine output are not the most important assessments prior to the administration of a beta-adrenergic blocking agent.
