Answer to Question 1

C
Feedback:
The patient will require a reduced dose of phenytoin (Dilantin) because disulfiram interferes with the metabolism of phenytoin. The patient will not require more frequent administration of disulfiram. The patient will not require a larger dose of disulfiram. The patient will not require increased administration of phenytoin.

Answer to Question 2

B
Feedback:
Decreased capillary permeability is among the effects of first-generation drugs. H1 receptor antagonists do not affect vitamin D, uric acid, or neurotransmitters.
