Answer to Question 1

ANS: D
Meperidine and promethazine have a synergistic effect on each other with a clinical effect that is substantially greater than the combined effect of the two.

Answer to Question 2

ANS: B
Cimetidine is an enzyme inhibitor that decreases the metabolism of drugs such as theophylline. If the cimetidine is discontinued, the theophylline dose should be decreased to avoid toxicity. The nurse should observe the patient for increased theophylline effects.
