The bnurse badministers bamiodarone b(Cordarone) bto ba bclient bwith bventricular
btachycardia. bWhich bmonitoring bby bthe bnurse bis bnecessary bwith bthis bdrug? bSelect ball
bthat bapply.
a. bRespiratory brate
b. bQT binterval
c. bHeart brate band brhythm
d. bMagnesium blevel
e. bUrine boutput b- bCorrect bAnswer b- bAnswer: bQT binterval; bHeart brate band brhythm;
bMagnesium blevel
Rationale: bAmiodarone bcauses bprolongation bof bthe bQT binterval, bwhich bcan bprecipitate
bdysrhythmia. bAntidysrhythmic bmedications bcause bchanges bin bcardiac brhythm band brate;
btherefore bmonitoring bof bheart brate band brhythm bis bneeded.Electrolyte bdepletion,
bspecifically bpotassium band bmagnesium, bmay bpredispose bto bfurther bdysrhythmia.
bAlthough bit bis balways bimportant bto bmonitor bvital bsigns band burine boutput, bthese
bassessments bare bnot bspecific bto bamiodarone.
The bnurse bis bcaring bfor ba bclient bwith bacute bcoronary bsyndrome b(ACS) band batrial
bfibrillation bwho bhas ba bnew bprescription bfor bmetoprolol b(Lopressor). bWhich bmonitoring bis
bessential bwhen badministering bthe bmedication?
a. bST bsegment
b. bHeart brate
c. bTroponin
d. bMyoglobin b- bCorrect bAnswer b- bAnswer: bHeart brate
Rationale: bThe beffects bof bmetoprolol bare bto bdecrease bheart brate, bblood bpressure, band
bmyocardial boxygen bdemand. bST bsegment belevation bis bconsistent bwith bMI; bit bdoes bnot
baddress bmonitoring bof bmetoprolol. bElevation bin btroponin bis bconsistent bwith ba bdiagnosis
bof bMI bbut bdoes bnot baddress bneeded bmonitoring bfor bmetoprolol. bElevation bin bmyoglobin
bis bconsistent bwith bmyocardial binjury bin bACS bbut bdoes bnot baddress bneeded bmonitoring
brelated bto bmetoprolol.
The bnurse bis bcaring bfor ba bclient bwith batrial bfibrillation. bIn baddition bto ban bantidysrhythmic,
bwhat bmedication bdoes bthe bnurse bplan bto badminister?
a. bHeparin
b. bAtropine
c. bDobutamine
,d. bMagnesium bsulfate b- bCorrect bAnswer b- bAnswer: bHeparin
Rationale: bClients bwith batrial bfibrillation bare bprone bto bblood bpooling bin bthe batrium,
bclotting, bthen bembolizing. bHeparin bis bused bto bprevent bthrombus bdevelopment bin bthe
batrium band bthe bconsequence bof bembolization b(i.e., bstroke).
The bnurse bis bcaring bfor ba bclient bon ba btelemetry bunit bwith ba bregular bheart brhythm band
brate bof b60; ba bP bwave bprecedes beach bQRS bcomplex, band bthe bPR binterval bis b0.24
bsecond. bAdditional bvital bsigns bare bas bfollows: bblood bpressure b118/68, brespiratory brate
b16, band btemperature b98.8° bF. bThe bfollowing bmedications bare bavailable bon bthe
bmedication brecord. bWhat baction bshould bthe bnurse btake?
a. bAdminister batropine.
b. bAdminister bdigoxin.
c. bAdminister bclonidine.
d. bContinue bto bmonitor. b- bCorrect bAnswer b- bAnswer: bContinue bto bmonitor.
Rationale: bThe bclient bis bdisplaying bsinus brhythm bwith bfirst-degree batrioventicular bheart
bblock; bthis bis busually basymptomatic band bdoes bnot brequire btreatment. bAtropine bis bused
bin bemergency btreatment bof bsymptomatic bbradycardia. bThis bclient bhas bnormal bvital
bsigns. bDigoxin bis bused bin bthe btreatment bof batrial bfibrillation, bwhich bis, bby bdefinition, ban
birregular brhythm. bClonidine bis bused bin bthe btreatment bof bhypertension; ba bside beffect bis
bbradycardia.
You bare bthe bcharge bnurse bon bthe btelemetry bunit band bare bresponsible bfor bmaking bclient
bassignments. bWhich bclient bwould bbe bappropriate bto bassign bto bthe bfloat bRN bfrom bthe
bmedical-surgical bunit?
a. bThe b64-year-old badmitted bfor bweakness bwho bhas ba bfirst-degree bheart bblock bwith ba
bheart brate bof b58 bbeats/min
b. bThe b71-year-old badmitted bfor bheart bfailure bwho bis bshort bof bbreath band bhas ba bheart
brate bof b120 bto b130 bbeats/min
c. bThe b88-year-old badmitted bwith ban belevated btroponin blevel bwho bis bhypotensive bwith ba
bheart brate bof b96 bbeats/min
d. bThe b92-year-old badmitted bwith bchest bpain bwho bhas bpremature bventricular bcomplexes
band ba bheart brate bof b102 bbeats/min b- bCorrect bAnswer b- bAnswer: bThe b64-year-old
badmitted bfor bweakness bwho bhas ba bfirst-degree bheart bblock bwith ba bheart brate bof b58
bbeats/min
Rationale: bThis bclient bhas ba bstable, basymptomatic bdysrhythmia, bwhich busually brequires
bno btreatment; bthis bclient bcan bbe bmanaged bby ba bnurse bwith bless bcardiac bdysrhythmia
btraining.
A bclient bwith batrial bfibrillation bwith brapid bventricular bresponse bhas breceived bmedication
bto bslow bthe bventricular brate. bThe bpulse bis bnow b88. bFor bwhich badditional btherapy bdoes
bthe bnurse bplan?
a. bSynchronized bcardioversion
b. bElectrophysiology bstudies b(EPS)
, c. bAnticoagulation
d. bRadiofrequency bablation btherapy b- bCorrect bAnswer b- bAnswer: bAnticoagulation
Rationale: bBecause bof bthe brisk bfor bthromboembolism, banticoagulation bis bnecessary.
