a) dPaCO2
b)pH
c)HCO3
d)PaO2 d- dcorrect danswer.a
The dnormal drange dfor dPaCO2 dis d35-45. dThis dpatient dis dexperiencing da dsuperimposed
drespiratory dalkalosis dlikely ddue dto dhyperventilation. dThe dnurse dshould dreport dthe
dPaCO2 dto dthe dphysician.
2) dA dnurse dmust dposition dthe dpatient dprone dafter dhis ddiagnosis dof dacute drespiratory
ddistress dsyndrome d(ARDS). dWhich dof dthe dfollowing dis da dbenefit dof dusing dthis dposition?
dSelect dall dthat dapply.
A)Decreased datelectasis
B)Reduced dneed dfor dendotracheal dintubation
c)Mobilization dof dsecretions
d)Decreased dpleural dpressure
e)Increased dresponse dto dcorticosteroid dtherapy d- dcorrect danswer.a, dc, dd
Decreased datelectasis", d"Mobilization dof dsecretions" dand d"Decreased dpleural dpressure"
dare dcorrect. dProne dpositioning, dor dplacing dthe dpatient dface ddown dwith dthe dhead dturned
dto dthe dside, dhelps dwith dpulmonary dfunction din dthe dpatient ddiagnosed dwith dARDS. dWhen
dthe dpatient dis dplaced din da dprone dposition, dthe dheart dand ddiaphragm dare dnot dpressing
dagainst dthe dlungs, dwhich dmeans dthat dpleural dpressure dis dreduced. dWhen dthere dis dless
dpressure dexerted don dthe dlungs, datelectasis ddecreases. dStudies dhave dshown dthat dmany
dpatients din dthe dprone dposition dhave dincreased dlung dsecretions, dwhich dimproves
doxygenation.
,-"Reduced dneed dfor dendotracheal dintubation" dis dincorrect. dThe dprone dposition dhas dnot
dbeen dshown dto ddecrease dthe dlikelihood dof dintubation.
-"Increased dresponse dto dcorticosteroid dtherapy" dis dincorrect dbecause dpositioning ddoes
dnot dchange dthe dbody's dresponse dto dsteroid dtherapy.

dadjust dto dreceiving dnutrients dagain, dwhich dcan dcause dshifts din delectrolytes din dthe dbody.
dThese dshifts din delectrolytes dcan dresult din dsudden dand doften dfatal dcomplications. dSigns
dand dsymptoms dof dre-feeding dsyndrome dinclude dconfusion dand dimpaired dmental dstatus,
