• Question I 1
1 Iout Iof I1 Ipoints
Ben Iis Ia I6-month Iold Iinfant Iwho Ihas Ia Ihistory Iof Irespiratory Iinfections. IHis Iparents Iare
Iconcerned Ithat Ihis Isymptoms Iare Iworsening Iand Ibring Ihim Ito Ihis Ipediatrician, IDr.

Johnson. IThey Iexplain Ithat Ihe Ihas Ia Ipersistent Icough Iand Isometimes Icoughs Iup Iphlegm.
IHe Ialso Iexperiences Iperiodic Iwheezing Iand Ishortness Iof Ibreath. IDr. IJohnson Inotes Ithat Ihis

Iweight Iand Iheight Ihave Inot Iincreased Ias Imuch Ias Ipredicted Isince Ihis Ilast Ivisit. IHe Iis

Iconcerned Ithat IBen Imay Ihave Ia Igenetic Icondition Icalled ICystic IFibrosis.




There Iare Iseveral Iways Ito Itest Ifor ICystic IFibrosis. IIn Iyour Iown Iwords,
I briefly I describe I2 Idiagnostic I tests Ithat I Dr. I Johnson I could I useIto

Idetermine Iif IBen Ihas ICystic IFibrosis.


Selected Two Itests Ithat IDr. IJohnson Icould Iuse Iwould Ibe Ia Isnasal Ipotential Idifference Itest, Ior Ia
IAnswer: IsweatItest. IWith Ia Inasal Ipotential Idifference Itest Ithe Idoctor Iwill Icheck Ithe Icells Iin Ihis

Inose Ito Isee Ihow Iwell Ithe Isalt Iis Imoving Iin Iand Iout Iof Ithem. IHe Ican Icheck Ithe Icells Iby
Iusing IelectrodesIon Ithe Ilining Iof Ithe Inose. IIf Ithe Iresults Icome Iback Iabnormal Ithis Icould
Ishow Ipositive Ifor ICystic IFibrosis. IThe Isecond Itest Ithat Ican Ibe Idone Iis Ia Isweat Itest. IThe

Idoctor Iwill Irub Ia Ispecial Ichemical Ithat Icauses Isweating Iand Ithen Iwill Icreate Ia Ismall

Ielectrical Icurrent Ion ItheIarea. IThe Isweat Iwill Ibe Iwiped Ioff Ion Ia Icloth Iand Itaken Ifor

Ianalyzing. ISomeone Iwho Ihas Itoo Imuch Isalt Iin Itheir Isweat Ican Ibe Idiagnosed Iwith ICystic

IFibrosis. IA Ipositive Idiagnosis Iwill Irequire Itwo Ipositive Iresults Iwhere Ithe Itests Iare Idone

• Question I 6
1 Iout Iof I1 Ipoints
In Iyour Iown Iwords, Ibriefly Idescribe Ihow Ithe ICystic IFibrosis Igene Iaffects Ithe Icell
Imembrane.




Selected The ICystic IFibrosis Igene Iaffects Ithe Ithe Icell Imembrane Iby Icreating Ia Iprotein ICTFR
IAnswer: I(Cystic IFibrosis ITransmembrane IConductance IRegulator) Ithat Iis Imutated. IThis Iprotein

Iis Iin Icells Ithat Inormally Iline Ithe Ilungs, Isweat Iglands, Iand Idigestive Itrack. IWhen Ithis
Iprotein Iis Imutated Iepithelial Icells Ican Ino Ilonger Iregulate Ihow Ichloride Imoves Ithrough
Ithe Icell Imembrane. IThis Icauses Ia Idisruption Iin Iwater Iand Isodium Ibalance Ineeded Ito

Icreate Ithe IthinIlining Iof Imucous Iin Ithe Ilungs, Ipancreas Iand Ipassageways Ito Iother Iorgans.

IWith Ithis Idisruption Iin Ibalance, Ithe Ithin Ilining Ibecomes Ithick, Isticky, Iand Istuck Iin Ithe

Irespiratory Iand Idigestive Isystems.
