o o o o o
Question o1
Which olayer oof othe oepidermis ois othe odeepest oand ocontains ostem ocells oresponsible ofor
ocontinuous ocell odivision?
A) oStratum ocorneum
B) oStratum olucidum
C) oStratum ogranulosum
D) oStratum obasale
Correct oAnswer: oD) oStratum obasale
Rationale: oThe ostratum obasale o(also ocalled ostratum ogerminativum) ois othe odeepest
oepidermal olayer, oconsisting o of oa osingle orow o of ocuboidal oto olow ocolumnar ostem ocells
othat odivide ocontinuously oto o produce o new okeratinocytes o.
Question o2
Which ocells oin othe oepidermis osynthesize othe opigment omelanin?
A) oKeratinocytes
B) oTactile ocells
C) oMelanocytes
D) oDendritic ocells
Correct oAnswer: oC) oMelanocytes
Rationale: oMelanocytes oare ofound oonly oin othe ostratum obasale oand osynthesize
omelanin, oa obrown oto o black opigment othat oprotects othe oskin ofrom o UV oradiation oand
ocontributes oto o skin ocolor o.
Question o3
What otype oof oepithelium omakes oup othe oepidermis?
,A) oSimple ocuboidal oepithelium
B) oStratified osquamous oepithelium
C) oSimple osquamous oepithelium
D) oTransitional oepithelium
Correct oAnswer: oB) oStratified osquamous oepithelium
Rationale: oThe oepidermis ois ocomposed oof okeratinized ostratified osquamous
oepithelium, owhich o provides o a odurable, oprotective obarrier. oThe osurface oconsists oof
odead ocells o packed o with okeratin o.
Question o4
Which oof othe ofollowing ois oNOT oa ofunction oof othe ointegumentary osystem?
A) oVitamin oD osynthesis
B) oThermoregulation
C) oCalcium ostorage
D) oSensation
Correct oAnswer: oC) oCalcium ostorage
Rationale: oCalcium ostorage ois oa ofunction oof othe oskeletal osystem, onot othe
ointegumentary osystem. oThe oskin ofunctions oinclude oresistance oto otrauma o and
oinfection, obarrier ofunctions, ovitamin oD osynthesis, osensation, othermoregulation, o and
ononverbal ocommunication o.
Question o5
A opatient ois oadmitted owith ofull-thickness oburns othat oappear ograyish-white oand ohave
ono osensation. oThe onurse ocorrectly oidentifies othese oas:
A) oFirst-degree oburns
B) oSecond-degree oburns
C) oThird-degree oburns
D) oSuperficial oburns
Correct oAnswer: oC) oThird-degree oburns
Rationale: oThird-degree o(full-thickness) oburns odestroy othe oentire oskin olayer,
oincluding othe odermis. oThey o appear ogray, owhite, oor oblack, oand othere ois o no osensation
, obecause onerve oendings oare odestroyed. oThese oburns orequire oskin ografts oas oskin ocan
oonly oregenerate ofrom othe oedges o.
Question o6
The odermis ois ocomposed oprimarily oof owhich otype oof oconnective otissue?
A) oAreolar oconnective otissue
B) oDense oirregular oconnective otissue
C) oAdipose otissue
D) oHyaline ocartilage
Correct oAnswer: oB) oDense oirregular oconnective otissue
Rationale: oThe odermis oconsists omainly oof odense oirregular oconnective otissue owith
ocollagen, oelastic, oand oreticular ofibers, o along owith ofibroblasts. oIt ois owell osupplied owith
oblood ovessels, oglands, oand onerve oendings o.
Question o7
Which oglands oproduce osebum oto olubricate oand oprotect othe oskin?
A) oEccrine oglands
B) oApocrine oglands
C) oSebaceous oglands
D) oMerocrine oglands
Correct oAnswer: oC) oSebaceous oglands
Rationale: oSebaceous oglands oare oflask-shaped oglands othat oproduce osebum, oan ooily
osubstance othat olubricates othe oskin o and o hair. oTheir oducts oopen ointo o hair ofollicles, oand
othey oare oclassified oas oholocrine oglands o.
Question o8
Which olayer oof othe oskin ois oalso oknown oas othe ohypodermis?
A) oEpidermis
B) oDermis
