Q:l Ifl thel bloodl pressurel obtainedl froml thel arteriall linel isl higherl thanl thel bloodl pressurel obtainedl froml al sphygmomanometerl (cuffl pressure).l Basedl uponl thisl information,l thel respiratoryl therapistl shouldl concludel that.l a.l Non-compliantl tubingl isl beingl used b.l Transducerl isl placedl tool low c.l Patientl wasl lyingl flatl duringl thel measurementl ofl thel arteriall linel pressure d.l Transducerl domel containedl airl bubbles

Answer:

Arteriall linel BPl andl cuffl pressurel shouldl bel thel same,l sol therel isl al problem.l Non- compliantl tubingl isl al goodl thingl becausel it'sl al stiffl tubing,l ifl transducerl isl placedl tool highl (abovel thel heart),l thel floodl willl havel tol gol uphilll andl youl willl getl al lowerl pressure;l transducerl domel containedl airl bubblesl wouldl givel youl erraticl readingsl butl notl al higherl reading,l butl ifl thel transducerl isl placedl tool lowl (belowl heart),l thel bloodl isl flowingl downhilll &l willl givel al higherl pressurel reading,l sol ANSWERl isl B

Q:l Al 2-yearl oldl childl entersl thel emergencyl room.l Thel motherl statesl thatl thel childl wasl playingl withl friendsl andl developedl violentl coughingl andl unilaterall wheezing.l Physicall examinationl revealsl al hyperresonantl percussionl notel onl thel leftl andl resonantl percussionl onl thel right.l Inspiratoryl andl expiratoryl chestl filmsl indicatel airl trappingl withl nol foreignl bodiesl "noted.l "l Thel respiratoryl therapistl shouldl suspectl thel childl has.l a.l pneumothorax b.l orthopnea c.l aspiratedl al foreignl object d.l tachyphylaxis

Answer:

Unilaterall wheezingl indicatesl aspiratedl objectl andl factl thatl thel childl wasl playingl withl friendsl causesl youl tol believel thel childl inhaledl al smalll toyl orl something,l hyperresonantl percussionl indicatesl airl trapping,l sol youl arel thinkingl foreignl objectl butl x-rayl saysl nol 1 / 4

foreignl bodiesl "noted.l "l Justl becausel itl saysl "noted"l doesl notl meanl somethingl isl notl there,l itl justl meansl itl couldl notl bel seenl onl thel xray,l alsol ifl thel childl hadl swallowedl al smalll plasticl toy,l "plastic"l doesl notl showl upl onl xraysl (radiolucent).l Thel ANSWERl isl C

Answer:

Sincel thel patientl receivedl Lasixl andl nasogastricl tube,l theyl arel losingl fluids,l andl al sidel effectl ofl fluidl lossl isl al decreasel inl electrolytes,l sol ANSWERl isl Bl (therel isn'tl enoughl evidencel ofl heartl attackl tol justifyl cardiacl enzymes,l alsol theyl arel usedl tol confirml al heartl attack).l

Q:l Whichl ofl thel followingl willl determinel aorticl pulsel pressure.l

a.l systolicl +l systolicl +l diastolic/3 b.l diastolicl +l pulsel pressure/3 c.l systolicl pressurel -l diastolicl pressure d.l strokel volumel xl heartl ratel xl 10.l

Q:l Al 32-weekl gestationall agel infantl isl receivingl mechanicall ventilationl forl hyalinel membranel disease.l Thel patientl requiredl al chestl tubel forl al persistentl pneumothorax.l Twol daysl laterl thel chestl radiographl revealsl bilaterall radiolucency,l midlinel mediastinum,l andl thel rightl hemidiaphragml slightlyl elevated.l Thisl wouldl indicate A.l atelectasis.l B.l bronchopulmonaryl dysplasia.l 2 / 4

C.l fluidl overload.l D.l resolutionl ofl al pneumothorax.l

Answer:

bilaterall meansl bothl sides,l radiolucencyl refersl tol dark,l midlinel mediastinuml isl rightl wherel isl shouldl be,l thel rightl hemidiaphragml slightlyl elevatedl isl normal;l sol thisl actuallyl indicatesl everythingl isl normal.l Withl atelectasisl wel wouldl seel patchyl infiltrates,l lossl ofl volume,l withl bronchopulmonaryl dysplasial itl wouldl lookl similarl tol ARDS,l withl fluidl overloadl youl wouldl seel patternl similarl tol butterflyl orl batwingl similarl tol pulmonaryl edema,l sol thel bestl

ANSWERl isl Dl andl thel pneumothoraxl hasl resolved.l
