Answer A measure of the extent of drug absorption for a given drug and route. Giving a med
through the IV, you will have 100% of the med in the bloodstream,none is lost.
15. First-Pass Effect
Answer The initial metabolism in the liver of a drug absorbed from theGI tract before the drug
reaches systemic circulation. If you give a PO med, the GIsystem digests, liver transforms, and
then it reaches the bloodstream. Not 100% ofthe med reaches the bloodstream, you lose some
as it travels.
