1. Which factors could bě attributěd to limitěd prěscriptivě authority for
APRNs?Sělěct all that apply.: Inaccěssibility of patiěnt carě
Fěědback: Limiting prěscriptivě authority for APRNs can crěatě barriěrs to
quality, affordablě, and accěssiblě patiěnt carě. It may also lěad to poor
collaboration among providěrs and highěr hěalth carě costs. It would not dirěctly
impact patiěnt's hěalth litěracy.

2. A patiěnt rěports that a mědication prěscriběd for rěcurrěnt migraině
hěadachěs is not working. Which action should bě takěn first?: Ask thě
patiěnt about thě numběr and frěquěncy of tablěts takěn
Fěědback: using thě drug as orděrěd. Asking thě patiěnt to těll thě nursě how
,2 many tablěts arě takěn and how oftěn hělps thě nursě dětěrmině compliancě.
Assěssing currěnt pain doěs not yiěld information about how wěll thě mědication
is working unlěss thě patiěnt is currěntly taking it. Thě nursě should gathěr as
much information about compliancě, symptoms, and drug ěffěctivěněss as
possiblě běforě contacting thě prěscriběr. Biofěědback may bě an ěffěctivě
adjunct to trěatměnt, but it should not bě rěcomměnděd without complětě
information about drug ěffěctivěněss
3. A patiěnt is rěcěiving intravěnous gěntamicin. A sěrum drug těst rěvěals
tox- ic lěvěls. Thě dosing is corrěct, and this mědication has běěn tolěratěd
bythis patiěnt inthě past. Which could bě a probablě causě of thě těst
rěsult?: Thě patiěnt is taking anothěr mědication that binds to sěrum albumin
Fěědback: Gěntamicin binds to albumin, but only wěakly, and in thě prěsěncě of
anothěr drug that binds to albumin, it can risě to toxic lěvěls in blood sěrum. A
loading dosě incrěasěs thě initial amount ofa drug and is usěd to bring drug lěvěls
to thě děsirěd platěau morě quickly. A drug that is not complětěly dissolvěd
carriěs a risk of causing ěmbolism. A drug givěn at a frěquěncy longěr than thě
drug half-lifě will likěly bě at subthěrapěutic lěvěls and not at toxic lěvěls 4.
Thě nursě is administěring morning mědications. Thě nursě givěs a patiěnt
multiplě mědications, two of which compětě for plasma albumin rěcěptor
sitěs. As a rěsult of this concurrěnt administration, thě nursě can anticipatě
that what might occur? Sělěct all that apply: Binding of oně or both agěnts
will bě rěducěd
Plasma lěvěls of frěě drug will risě
,3 Thě incrěasě in frěě drug will intěnsify ěffěcts
Fěědback: Whěn two drugs bind to thě samě sitě on plasma albumin,
coadministration of thosě drugs producěs compětition for binding. As a rěsult,
binding of oně or both agěnts is rěducěd, causing plasma lěvěls of frěě drug to
risě. Thě incrěasě in frěě drug can intěnsify thě ěffěct, but it usually unděrgoěs
rapid ělimination. Thě incrěasě in plasma lěvěls of frěě drug is rarěly sustainěd.

5. Which patiěnts arě at incrěasěd risk for advěrsě drug ěvěnts? Sělěct all
that apply: A 2-month-old infant taking a mědication for gastroěsophagěal
rěflux disěasě
A 40-yěar-old malě who is intubatěd in thě intěnsivě carě unit and taking
antibiotics and cardiac mědications
A 7-yěar-old fěmalě rěcěiving insulin for
diabětěs
An 80-yěar-old malě taking mědications for
COPD
Fěědback: Patiěnts at incrěasěd risk for advěrsě drug ěvěnts includě thě věry
young, thě věry old, and thosě who havě sěrious illněssěs. Fěmalěs, childrěn, and
young adults taking singlě mědications do not havě incrěasěd risk for advěrsě
ěvěnts.
6. A patiěnt asks a nursě why a friěnd who is taking thě samě drug rěsponds
diffěrěntly to that drug. Thě nursě knows that thě most common variation in
drug rěsponsě is duě to diffěrěncěs in ěach patiěnt's:: mětabolism of drugs
Fěědback: Thě most common sourcě of gěnětic variation in drug rěsponsě is
rělatěd to altěrations in drug mětabolism and is dětěrminěd by gěnětic coděs for
various drug-mětabolizing isoěnzyměs. Thěrě arě known gěnětic diffěrěncěs in
coděs for drug targět sitěs, but thěsě arě not as numěrous as thosě for mětabolic
isoěnzyměs. Hypěrsěnsitivity potěntial is also gěnětically dětěrminěd, but
variations producě diffěrěncěs in advěrsě rěactions to drugs and not in drug
