Answer to Question 1

B
When a drug binds to a receptor, it mimics or blocks the actions of the usual endogenous regula-tory molecules, either increasing or decreasing the rate of the physiologic activity normally con-trolled by that receptor. It does not alter the activity of the receptor and does not give the receptor a new function.

Answer to Question 2

D
Balanced anesthesia is the use of a combination of drugs, along with an inhaled anesthetic, to produce effects that cannot safely be accomplished with inhalation anesthesia alone. These ad-junct drugs are used to help induce anesthesia, provide muscle relaxation, and increase analgesia so that a lower and safer dose of the inhalation anesthetic can be used. The other three options describe characteristics of an ideal anesthetic, which does not exist; to get these effects, a com-bination of other drugs must be used.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
