ANS: y D
With yconfrontation, ythe yrespiratory ytherapist yfocuses ythe ypatient’s yattention yon yan yaction, yfeeling, yor
ystatement ymade yby ythe ypatient. yThis ymay yprompt ya yfurther ydiscussion. yReflection yhelps ythe ypatient
yfocus yon yspecific yareas yand ycontinues yin yhis/her yown yway. yFacilitation yencourages ypatients yto ysay
ymore, yto ycontinue ywith ythe ystory. yThe yrespiratory ytherapist yshould yavoid ygiving yadvice, yusing
yavoidance ylanguage, yand yusing ydistancing ylanguage.
10. When yclosing ythe yinterview, ythe yrespiratory ytherapist yshould ydo ywhich yof ythe yfollowing?
1. Recheck ythe ypatient’s yvital ysigns.

6. In ypatients ywith ychronically yhigh yPaCO2 yand ylow yPaO2 ywhich yof ythe yfollowing yis ythe
yprimary yreceptor ysite yfor ythe ycontrol yof yventilation?
a. Central ychemoreceptors
b. Peripheral ychemoreceptors
c. Juxtapulmonary-capillary y receptors
d. Aortic yand ycarotid ysinus ybaroreceptors
ANS: y B
When ythe yperipheral ychemoreceptors yare yactivated, yan yafferent y(sensory) ysignal yis ysent yto ythe
yrespiratory ycenters yof ythe ymedulla yby yway yof ythe yglossopharyngeal ynerve y(cranial ynerve yIX) yfrom ythe
ycarotid ybodies yand yby yway yof ythe yvagus ynerve y(cranial ynerve yX) yfrom ythe yaortic ybodies. yEfferent
y(motor) ysignals yare ythen ysent yto ythe yrespiratory ymuscles, ywhich yresults yin yan yincreased yrate yof
ybreathing. yIt yshould ybe ynoted ythat yin ypatients ywho yhave ya ychronically yhigh yPaCO2 yand ylow yPaO2,
ythe yperipheral ychemoreceptors yare ythe yprimary yreceptor ysites yfor ythe ycontrol yof yventilation.
7. Which yof ythe yfollowing yare yconsidered yaccessory ymuscles yof yinspiration?
