A nurse educator is reviewing medication dosages and factors that influence medication
metabolism with a group of nurses. Medication dosages may need to be decreased for which of
the following reasons? (Select all that apply.)
A. Increased renal excretion
B. Increased medication-metabolizing enzymes
C. Liver failure

E. Concurrent use of medication metabolized by the same pathway - ANS 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 medications.

dosage. Increased medication-metabolizing enzymes can decrease the concentration of the
medication. The dose might need increased. Peripheral vascular disease may impair
distribution, and more of the medication may be needed.
