NURS 6320 Final Group 5 Ch 32 examquestions with complete solutions 2024
What jis jthe jinitiating jevent jthat jleads jto jthe jdevelopment jof jatherosclerosis? j
a. jRelease jof jthe jinflammatory jcytokines j
b. jMacrophages jadhere jto jvessel jwalls. j
c. jInjury jto jthe jendothelial jcells jthat jline jthe jartery jwalls j
d. jRelease jof jthe jplatelet-deprived jgrowth jfactor j- jANS✓✓-ANS: jC j
Atherosclerosis jbegins jwith jan jinjury jto jthe jendothelial jcells jthat jline jthe
jarterial jwalls. jPossible jcauses jof jendothelial jinjury jinclude jthe jcommon jrisk
jfactors jfor jatherosclerosis, jsuch jas jsmoking, jhypertension, jdiabetes, jincreased
jlevels jof jlow-density jlipoprotein j(LDL), jdecreased jlevels jof jhigh-density
jlipoprotein j(HDL), jand jautoimmunity. jThe jremaining joptions joccur jonly jafter
jthe jendothelial jcells jare jinjured
What jis jthe jeffect jof joxidized jlow-density jlipoproteins j(LDLs) jin
jatherosclerosis? j
a. jLDLs jcause jsmooth jmuscle jproliferation. j
b. jLDLs jcause jregression jof jatherosclerotic jplaques. j
c. jLDLs jincrease jlevels jof jinflammatory jcytokines. j
d. jLDLs jdirect jmacrophages jto jthe jsite jin jthe jendothelium. j- jANS✓✓-ANS: jA j
Oxidized jLDLs jare jtoxic jto jendothelial jcells, jcause jsmooth jmuscle jproliferation,
jand jactivate jfurther jimmune jand jinflammatory jresponses. jThis jselection jis jthe
jonly joption jthat jaccurately jidentifies jthe jeffects jof jLDLs.
Which jinflammatory jcytokines jare jreleased jwhen jendothelial jcells jare jinjured? j
a. jGranulocyte-macrophage jcolony-stimulating jfactor j(GM-CSF) j
, b. jInterferon-beta j(IFN-β), jinterleukin j6 j(IL-6), jand jgranulocyte jcolony-
stimulating jfactor j(G-CSF) j
c. jTumor jnecrosis jfactor-alpha j(TNF-α), jinterferon-gamma j(IFN-γ), jand
jinterleukin j1 j(IL-1) j
d. jInterferon-alpha j(IFN-α), jinterleukin-12 j(IL-12), jand jmacrophage jcolony-
stimulating jfactor j(M-CSF) j- jANS✓✓-ANS: jC j
Numerous jinflammatory jcytokines jare jreleased, jincluding jTNF-α, jIFN-γ, jIL-1,
jtoxic joxygen jradicals, jand jheat jshock jproteins. jThis jselection jis jthe jonly
joption jthat jaccurately jidentifies jwhich jinflammatory jcytokines jare jassociated
jwith jendothelial jcell jinjury
When jendothelia jcells jare jinjured, jwhat jalteration jcontributes jto
jatherosclerosis? j
a. jThe jrelease jof jtoxic joxygen jradicals jthat joxidize jlow-density jlipoproteins
j(LDLs). j
b. jCells jare junable jto jmake jthe jnormal jamount jof jvasodilating jcytokines. j
c. jCells jproduce jan jincreased jamount jof jantithrombotic jcytokines. j
d. jCells jdevelop ja jhypersensitivity jto jhomocysteine jand jlipids. j- jANS✓✓-ANS:
jB j
Injured jendothelial jcells jbecome jinflamed jand jcannot jmake jnormal jamounts jof
jantithrombotic jand jvasodilating jcytokines. jThis jselection jis jthe jonly joption
jthat jaccurately jidentifies jthe jfactor jthat jcontributes jto jatherosclerosis.
What jeffect jdoes jatherosclerosis jhave jon jthe jdevelopment jof jan janeurysm? j
a. jAtherosclerosis jcauses jischemia jof jthe jintima. j
b. jIt jincreases jnitric joxide. j
c. jAtherosclerosis jerodes jthe jvessel jwall. j
d. jIt jobstructs jthe jvessel j- jANS✓✓-ANS: jC j
Atherosclerosis jis ja jcommon jcause jof janeurysms jbecause jplaque jformation
jerodes jthe jvessel jwall. jThis jselection jis jthe jonly joption jthat jaccurately
jidentifies jthe jeffect jthat jatherosclerosis jhas jon janeurysm jdevelopment
