PATIENT,ASSESSMENT:
All,the,following,could,cause,capnography,to,go,from,3,6,to,30,EXCEPT:

B.,Hyperventilation
C.,pulmonary,emboli
D.,Hypovolemia,ANS,-
Endotracheal,tube,positioned,in,right,mainstem,bronchus,is,a,problem,but,the,co2,reading,would,not,ch
ange,,so,
ANSWER,is,A.
What,is,the,target,Vt,for,individual,on,mechanical,ventilation,ANS,-6-
8,ml/kg,(of,ideal,body,weight),This,is,new,strategy,as,of,January,2015
Is,the,following,Static,OR,Dynamic,Compliance:
Means,flow,throughout,the,respiratory,system,has,stopped,and,all,ventilatory,muscle,activity,is,absent.,_
______,conditions,can,be,imposed,with,an,inspiratory,pause,when,a,patient,is,sedated,and,mechanically,
ventilated.,ANS,-Static,Compliance
Is,the,following,Static,OR,Dynamic,Compliance:
Flow,at,airway,opening,is,zero.,Mechanics,are,evaluated,under,______,conditions,,when,non-
intubated,patient,breathes,spontaneously.,ANS,-Dynamic,Compliance
A,balloon,tipped,flow,directed,catheter,is,positioned,in,the,pulmonary,artery,with,the,balloon,deflated.,
Which,of,the,following,pressures,will,be,measured,by,the,proximal,lumen:
a.,Cvp
b.,Pap
c.,Pwp
,d.,Map,ANS,-ANSWER,is,A.,Cvp,=,deflated/proximal,lumen
Pap,=,deflated/distal
Pwp,=,inflated/wedged
All,of,the,following,will,affect,the,accuracy,of,a,capnography,EXCEPT
a.,Long,sampling,line
b.,Low,sampling,flow
c.,Condensation,in,the,tubing
d.,Use,of,desiccant,ANS,-
Gas,will,pass,through,and,out,of,a,long,sampling,line,before,reaching,analyzer,so,,low,sampling,flow,will,
not,give,you,enough,information,for,a,good,reading,,and,condensation,as,a,rule,is,always,a,problem,espe
cially,in,analyzers.,Dessicant,removes,moisture,from,the,gas,,which,is,a,good,thing,,so,
ANSWER,is,D
A,1000,g,neonate,(normal,baby,is,3000,g),is,stable,in,nicu.,Which,of,the,following,should,the,respiratory,t
herapist,use,to,monitor,the,neonates,overall,cardiopulmonary,status.
a.,TcPCO2,and,TcPO2,monitor
b.,Arterial,blood,gas,analysis,Q4
c.,SpO2,monitor
d.,Capillary,gas,analysis,Q8,ANS,-
Since,the,baby,is,stable,,go,less,invasive,,also,go,continuous,monitoring,(not,4,hour,or,8,hour),,Transcuta
neous,(Tc),continuous,monitoring,of,CO2,and,O2,is,the,best.,Answer,is,A
A,unilateral,wheeze,would,most,likely,indicate,which,of,the,following.
a.,Asthma
b.,Atelectasis
c.,Foreign,body,aspiration
d.,Epiglottitis,ANS,-
You,wouldn't,have,asthma,on,just,one,side,(unilateral),,atelectasis,would,cause,diminished,breath,sound
s,,with,epiglottitis,you,would,get,stridor,,since,you,are,only,hearing,wheezing,on,one,side,,you,are,hearin
g,it,on,the,side,where,you,aspirated,something,,
,so,ANSWER,is,C
All,of,the,following,would,be,associated,with,the,presence,of,a,pneumothorax,EXCEPT
a.,Tracheal,deviation
b.,Dull,percussion
c.,Absent,breath,sounds
d.,Respiratory,distress,ANS,-
With,pneumothorax,you,would,hear,a,high,pitch,hyperresonnance,,breath,sounds,would,be,absent,,and,
respiratory,distress,could,be,present.,Dull,percussion,would,NOT,be,present,,
so,ANSWER,is,B.
What,should,you,recommend,FIRST,for,a,patient,with,multifocal,pvc's
a.,Administration,of,lidocaine
b.,Administration,of,100%,oxygen
c.,Administration,of,atropine
d.,Administration,of,epinephrine,ANS,-
Multiple,pvc's,coming,from,multiple,locations,(multifocal),is,a,real,problem,and,you,should,administer,ox
ygen,FIRST,,so,ANSWER,is,B.,lidocaine,will,help,reduce,irritability,of,heart,and,help,with,pvc's,but,would,n
ot,be,first,option,,atropine,is,used,for,bradycardia,and,cardiac,irregularities,but,not,pvc's,,epinephrine,is,
emergency,drug,not,for,pvc's,but,more,for,pulseless,ventricular,tachycardia,or,ventricular,fibrilation,whe
re,heart,is,not,responding,.
What,is,the,normal,range,for,the,mean,pulmonary,artery,pressure,in,an,adult
a.,2-6,mm,Hg
b.,4-12,mmHg
c.,9-18,mmHg
d.,21-28,mmHg,ANS,-Mean,pulmonary,artery,pressure,in,an,adult,should,be,in,the,teens,
so,best,ANSWER,is,C
, A,patient,in,the,emergency,dept,has,frothy,secretions,,moist,crackles,,and,tachypnea.,The,patient,has,ma
rked,dyspnea,and,a,history,of,heart,disease.,Which,of,the,following,should,the,respiratory,therapist,reco
mmend.
1.suction,immediately
2.administer,100%,oxygen
3.place,in,Fowlers,position
4.administer,furosemide,ANS,-
This,is,an,emergency,,they,are,having,heart,problems,,dyspnea,,frothy,secretions,indicating,severe,pulm
onary,edema,,etc.,so,100%,oxygen,immediately,,having,the,patient,in,the,Fowlers,position,(an,upright,po
sition),will,help,pull,fluid,down,away,from,the,lungs,,furosemide,is,a,lasix,(loop,diuretic),which,gets,rid,of,
excess,fluid.,You,do,NOT,suction,someone,with,frothy,secretions,and,heart,problems,,this,just,delays,app
ropriate,therapy.,So,ANSWER,is,2,3,4

a.,Bronchiectasis
b.,Congestive,heart,failure
c.,Pneumonia
d.,Croup,ANS,-
Crackles,are,associated,with,fluid,so,a,,b,,and,c,would,be,good,answers,,but,"fine,crepitant",crackles,indic
ates,fluid,entering,alveoli,(pulmonary,edema),which,is,most,often,caused,by,heart,failure,so,the,best,ANS
WER,is,B.,(with,croup,you,would,hear,more,of,a,stridor,sound).
A,patient,is,found,in,full,cardiopulmonary,arrest.,CPR,is,started,and,the,patient,is,orally,intubated,with,an
,EtCO2,monitor,attached.,Which,of,the,following,EtCO2,patterns,would,the,respiratory,therapist,expect,t
o,observe,on,the,monitor?
a.,Initially,high,,then,falling
b.,Initially,low,,then,rising
c.,Initially,high,,stays,high
d.,Initially,low,,stays,low,ANS,-
Full,cardiac,arrest,will,cause,the,CO2,in,the,lungs,to,slowly,dissipate,out,because,no,blood,is,flowing,,the
n,during,CPR,when,you,get,blood,flowing,,the,CO2,should,slowly,rise,back,up;,
so,ANSWER,is,B
