E. Concurrent use of medication metabolized by the same pathway
CORRECT ANSWERS ANS: C, E
Liver failure decreases metabolism and thus increase the concentration of medication. This may
require decreasing the dosage of medication. When two medications are metabolized in the same
way, they may compete for metabolism, thereby increasing the concentration of one or both

medication. The dose might need increased. Peripheral vascular disease may impair distribution,
and more of the medication may be needed.
