What's first-pass effect? - ANS How much of an oral medication is metabolized in the liver

What would it mean if a medication had a high first-pass effect? - ANS A drug with a high

What's a prodrug? Who would it not be good for? - ANS It's not bioavailable until it's
metabolized in the liver. Wouldn't be good for a pt w/ a bad liver
Explain protein binding - ANS Drugs that bind to protein leave less circulating drug that's
available to the tissues, because the protein bound drug is held within the vascular system. A
decrease in protein levels will cause drug levels to rise and possibly be toxic. Multiple protein
bound drugs that compete for protein will result in higher blood levels of one or more of the
drugs.
, Synergistic VS additive effect - ANS Syn: Drugs work better in combination than alone
Add: Drugs with similar effects allow for less of each drug to be used to avoid A/Es

aren't missed and eliminated during the hospital stay (i.e. glaucoma drops, insulin) and to make
sure newly recorded meds aren't incompatible or redundant w/ meds the pt's already taking
Who does medication reconciliation and when is it done? - ANS The nurse upon
admission, transfer to a higher or lower level of care, and upon discharge. The list is compiled
by the nurse and reviewed with the provider.
When are peak and trough levels drawn? What do they tell you? - ANS PEAK: @ highest
concentration of the medicaton after giving and it tells you if you have a high enough blood level
of the drug to kill the bugs
TROUGH: Drawn immediately prior to the dose and tells you if the dose remains too high and
may lead to nephrotoxicity
In which trimester of pregnancy are meds most likely to be teratogenic? - ANS 1st
In which trimester of pregnancy is drug transfer to the fetus most likely? - ANS 3rd
