, 1. CHAPTER 1 — THE MAIN THEMES OF MICROBIOLOGY vnursing
vstudent vasks vwhy vmicrobiology vis vimportant vto vallied v health
vprofessionals. vWhich vreply vbest vexplains v the vprimary vreason vmicrobiology
vis vessential vin vclinical v practice?
A. It vprovides va vcomplete vlist vof vall vpathogenic vorganisms.
B. It vexplains v how vmicroorganisms v cause vdisease vand vhow vto vprevent
vtheir vspread.
C. It vteaches vsurgical vprocedures vrequired vto vtreat vinfections.
D. It vfocuses von veconomic vimpacts vof vinfectious v disease vcontrol.
Answer: vB.
Rationale:vMicrobiology vhelps vclinicians v understand vpathogen vbiology, vmodes vof
vtransmission, v host vresponse, vand vprevention/control vstrategies v (e.g., vasepsis,
vvaccines, vantibiotics). vOptions vA, vC, vand vD vare veither v incomplete vor virrelevant v to
vwhy vmicrobiology vis vessential vin vclinical v care.
2. Which vone vof vthe vfollowing v best vdescribes vthe vconceptvof
v“emerging vinfectious vdisease”?
A. A vdisease vthat vis veradicated vworldwide.
B. An vinfection vthat vbecomes vclinically v less vsevere vover vtime.
C. A vdisease vthat vappears vin va vpopulation vfor vthe vfirst vtime v or vreappears
vafter va vsignificant v decline.
D. Any vdisease vcaused vby vviruses v only.
Answer: vC.
Rationale:vEmerging v infectious v diseases vnewly v appear vor vreappear v(e.g.,
vEbola, vSARS-CoV-2). vThey vare vnot vlimited v to vviruses v and vare vnot veradicated
v diseases.
3. A vpatient vdevelops va vsecondaryvinfection vafter vinfluenza v due vto
vcolonizing vbacteria. vWhich vterm vbest vfits vthe vbacterial vinfection?
A. Latent vinfection
B. Primary vpathogen
C. Opportunistic vinfection
D. Congenital vinfection
Answer: vC.
,Rationale: vAn vopportunistic vinfection v occurs vwhen vnormal vdefenses vare
vcompromised v(influenza v damages vrespiratory vepithelium), v allowing v normally
v non- vinvasive v organisms vto vcause vdisease. vPrimary v pathogens vcause vdisease vin
vhealthy vhosts; vlatent v is vdormant; vcongenital vis vpresent vat vbirth.
4. Which vof vthe vfollowing v statements vabout vnormal vmicrobiota v(microflora)
v is vTRUE?
A. They vare valways vharmful vand vshould vbe veliminated.
B. They vprovide vbenefits vsuch vas vcompetitive vexclusion vand
vvitamin vproduction.
C. They vare vthe vsame vfor vevery vhuman v being.
D. They vonly vexist von vthe vskin.
Answer: vB.
Rationale:vNormal vmicrobiota vbenefit vhosts vby vcompetitive v exclusion, vvitamin
vsynthesis, vand vimmune v system vdevelopment. vThey vvary vbetween vindividuals v and
voccur von vmany v body vsites v(gut, vskin, vmucosa).
5. A vsmall voutbreak vof vfoodbornevillness v occurred vafter va vcatered v event.
vThe vinstructor vasks vwhat vpublic vhealth v role vepidemiology v played.
vWhich vstatement vis vcorrect?
A. Epidemiology vis vresponsible vfor vtreating vthe vsick.
B. Epidemiology vtraces vpatterns, vcauses,vand vcontrolvmeasures vfor vdisease
vin vpopulations.
C. Epidemiology v only vdocuments vdeaths.
D. Epidemiology v only vstudies vchronic vdiseases.
Answer: vB.
Rationale:vEpidemiology vinvestigates v distribution vand vdeterminants v of vhealth
vevents, vhelping videntify v sources v(e.g., vcontaminated v food), vmodes vof vtransmission,
vand vinterventions. v It’s vnot vlimited v to vtreatment, v deaths, vor vchronic vdisease.
6. Which vcharacteristic v separates vviruses vfrom vcellular v life?
A. Presence vof vDNA vor vRNA vgenome
B. Capability vto vreplicate vonly vinside va vhostvcell
, C. Having va vprotein vcoat
D. Ability vto vevolve
Answer: vB.
Rationale:vViruses vare vobligate vintracellular v parasites—they vrequire vhost
vmachinery vto vreplicate. vCellular v life vconducts vindependent vmetabolism; vviruses
vmay vhave vDNA vor vRNA vand vcan vevolve, v and vmany vhave va vprotein vcapsid,
vbut vobligate vintracellular v replication vis vdefining.
7. A vclinician v hears vthe vphrase v“infection vdoes vnot valways v equal
vdisease.” vWhich vexample v supports vthat vstatement?
A. Symptomatic vinfluenza v infection vin va vpatient vwith vfever.
B. Carriage vof vStaphylococcus vaureus vin vthe vanterior v nares vof va
vhealthy vperson.
C. Death vcaused vby vsepsis.
D. Severe vpneumonia v in van vimmunocompromised v patient.
Answer: vB.
Rationale:vCarriage v(colonization) vshows vinfection vwithout v clinical v disease.
vInfection vcan vbe vasymptomatic; vdisease voccurs vwhen vhost vdamage vor
vsymptoms vmanifest.
8. Which vof vthe vfollowing v best vreflects v Koch’s vpostulates’ vmain v contribution
vto vmicrobiology?
A. Measuring vmicrobial vgrowth vrates vin vthe vlab.
B. Establishing vcriteria vto vlink va vspecific vmicroorganism vto va
vparticular vdisease.
C. Describing vadaptive vimmune v responses.
D. Explaining v how vantibiotics v work.
Answer: vB.
Rationale: vKoch’s vpostulates vwere vfoundational vin vdemonstrating vcausation
vbetween vmicrobes vand vdisease v(isolate v organism, vreproducevdisease vin vmodel, vre-
visolate). v They vdo vnot vcover vimmunity v or vantibiotics.
9. A vnewly v discovered vbacterium vis vunable v to vbe vcultured v on vstandard
vmedia vbut vis vconsistently vfound vin vpatients v with va vdisease. vWhich vmodern
vtechnique vhelps vassociate vthe vbacterium vwith v disease vdespite vKoch’s
vpostulates
