NR 464 Exam 2 (Cardiac and Endocrine)questions with complete solutions 2024
The jnurse jis jcaring jfor ja jpatient jwho jhas jhad jan jECG. jThe jnurse jnotes jthat
jleads jI, jII, jand jIII jdiffer jfrom jone janother jon jthe jcardiac jrhythm jstrip. jHow
jshould jthe jnurse jbest jrespond? j- jANS✓✓-Ans: jRecognize jthat jthe jview jof jthe
jelectrical jcurrent jchanges jin jrelation jto jthe jlead jplacement.
Feedback:Rational
Each jlead joffers ja jdifferent jreference jpoint jto jview jthe jelectrical jactivity jof jthe
jheart. jThe jlead jdisplays jthe jconfiguration jof jelectrical jactivity jof jthe jheart.
The jnurse jis janalyzing ja jrhythm jstrip. jWhat jcomponent jof jthe jECG
jcorresponds jto jthe jresting jstate jof jthe jpatient's jheart? j- jANS✓✓-The jT jwave
jspecifically jrepresents jventricular jmuscle jdepolarization, jalso jreferred jto jas jthe
jresting jstate.
The jnursing jeducator jis jpresenting ja jcase jstudy jof jan jadult jpatient jwho jhas
jabnormal jventricular jdepolarization. jThis jpathologic jchange jwould jbe jmost
jevident jin jwhat jcomponent jof jthe jECG? j- jANS✓✓-The jQRS jcomplex
jrepresents jthe jdepolarization jof jthe jventricles jand, jas jsuch, jthe jelectrical
jactivity jof jthat jventricle.
An jadult jpatient jwith jthird-degree jAV jblock jis jadmitted jto jthe jcardiac jcare junit
jand jplaced jon jcontinuous jcardiac jmonitoring. jWhat jrhythm jcharacteristic jwill
jthe jECG jmost jlikely jshow? j- jANS✓✓-Fewer jQRS jcomplexes jthan jP jwaves
Rational
In jthird-degree jAV jblock, jno jatrial jimpulse jis jconducted jthrough jthe jAV jnode
jinto jthe jventricles. jAs ja jresult, jthere jare jimpulses jstimulating jthe jatria jand
jimpulses jstimulating jthe jventricles. jTherefore, jthere jare jmore jP jwaves jthan
jQRS jcomplexes jdue jto jthe jdifference jin jthe jnatural jpacemaker j(nodes) jrates jof
jthe jheart.
The jnurse jis jwriting ja jplan jof jcare jfor ja jpatient jwith ja jcardiac jdysrhythmia.
jWhat jwould jbe jthe jmost jappropriate jgoal jfor jthe jpatient? j- jANS✓✓-For jpatient
jsafety, jthe jmost jappropriate jgoal jis jto jmaintain jcardiac joutput jto jprevent
jworsening jcomplications jas ja jresult jof jdecreased jcardiac joutput.
, A jpatient jhas jreturned jto jthe jcardiac jcare junit jafter jhaving ja jpermanent
jpacemaker jimplantation. jFor jwhich jpotential jcomplication jshould jthe jnurse
jmost jclosely jassess jthis jpatient? j- jANS✓✓-Bleeding, jhematomas, jlocal
jinfections, jperforation jof jthe jmyocardium, jand jtachycardia jare jcomplications jof
jpacemaker jimplantations. jThe jnurse jshould jmonitor jfor jchest jpain jand
jbradycardia, jbut jbleeding jis ja jmore jcommon jimmediate jcomplication.
A jpatient jthe jnurse jis jcaring jfor jhas ja jpermanent jpacemaker jimplanted jwith
jthe jidentification jcode jbeginning jwith jVVI. jWhat jdoes jthis jindicate? j- jANS✓✓-
The jidentification jof jVVI jindicates jventricular jpaced, jventricular jsensed,
jinhibited.
The jnurse jis jcaring jfor jan jadult jpatient jwho jhas jgone jinto jventricular
jfibrillation. jWhen jassisting jwith jdefibrillating jthe jpatient, jwhat jmust jthe jnurse
jdo? j- jANS✓✓-When jdefibrillating jan jadult jpatient, jthe jnurse jshould jmaintain
jgood jcontact jbetween jthe jpaddles jand jthe jpatient's jskin jto jprevent jarcing,
japply jan jappropriate jconducting jagent j(not jwater) jbetween jthe jskin jand jthe
jpaddles, jand jensure jthe jdefibrillator jis jin jthe jnonsync jmode. j"Clear" jshould jbe
jcalled jthree jtimes jbefore jdischarging jthe jpaddles.
A jpatient jwho jis ja jcandidate jfor jan jimplantable jcardioverter jdefibrillator j(ICD)
jasks jthe jnurse jabout jthe jpurpose jof jthis jdevice. jWhat jwould jbe jthe jnurse's
jbest jresponse? j- jANS✓✓-The jICD jis ja jdevice jthat jdetects jand jterminates jlife-
threatening jepisodes jof jventricular jtachycardia jand jventricular jfibrillation.
A jnurse jis jproviding jhealth jeducation jto ja jpatient jscheduled jfor jcryoablation
jtherapy. jThe jnurse jshould jdescribe jwhat jaspect jof jthis jtreatment? j- jANS✓✓-
Cryoablation jtherapy jinvolves jusing ja jcooled jprobe jto jcreate ja jsmall jscar jon
jthe jendocardium jto jeliminate jthe jsource jof jthe jdysrhythmias.
A jnurse jis jproviding jhealth jeducation jto ja jpatient jscheduled jfor jEndocardium
jresection. jThe jnurse jshould jdescribe jwhat jaspect jof jthis jtreatment? j- jANS✓✓-
Endocardium jresection jinvolves jpeeling jaway ja jspecified jarea jof jthe
jendocardium.
A jnurse jis jproviding jhealth jeducation jto ja jpatient jscheduled jfor jElectrical
jablation. jThe jnurse jshould jdescribe jwhat jaspect jof jthis jtreatment? j- jANS✓✓-
Electrical jablation jinvolves jusing jshocks jto jeliminate jthe jarea jcausing jthe
jdysrhythmias.
A jnurse jis jproviding jhealth jeducation jto ja jpatient jscheduled jfor jRadio
jfrequency jablation. jThe jnurse jshould jdescribe jwhat jaspect jof jthis jtreatment? j-
jANS✓✓-Radio jfrequency jablation juses jhigh-frequency jsound jwaves jto jdestroy
jthe jarea jcausing jthe jdysrhythmias.
