Answer to Question 1

C, D, E
Feedback:
Caution must be used when these drugs are used with any other central nervous system suppressants. Barbiturates can cause decreased effectiveness of theophylline, oral anticoagulants, beta-blockers, corticosteroids, hormonal contraceptives, phenylbutazones, metronidazole, quinidine, and carbamazepine. Combinations of barbiturate anesthetics and narcotics may produce apnea more commonly than occurs with other analgesics. Thyroid hormone and ibuprofen have no known drug interactions with barbiturates.

Answer to Question 2

B
Feedback:
Nizatidine differs from the other three drugs in that it is eliminated by the kidneys, with no first-pass metabolism in the liver. It is the drug of choice for patients with liver disease or dysfunction.
