Answer to Question 1

B
Feedback:
Neostigmine (Prostigmin) stimulates the parasympathetic nervous system. It does not stimulate the sympathetic nervous system, cardiac system, or respiratory system.

Answer to Question 2

B
Feedback:
Oral and IV acyclovir are excreted in the urine, and the dose should be decreased in patients who are older or have renal impairment. The dose is not smaller due to herpes simplex. The dose is not higher in treating genital herpes. The dose should be lower if the creatinine level is above 4.0 mg/dL.
