1. What zis zthe zname zof zthe zreceptor zsites zthat zare zlocated zin zthe zperipheral zvasculature, zthe zheart,
zbronchial zmuscle, zand zbronchial zblood zvessels?
a. Beta z2 zreceptors c. Alpha zreceptors
b. Gamma zreceptors d. z z Beta z1 zreceptors
ANS: z C
Alpha zreceptors zare zlocated zin zthe zperipheral zvasculature, zthe zheart, zbronchial zmuscle, zand
zbronchial zblood zvessels.
PTS: z 1
2. Which zreceptor zsite zresults zin ztachycardia, zan zincreased zpotential zfor zarrhythmias, zand zan
zincreased zcardiac zoutput?
a. Beta z1 zreceptor c. Alpha zreceptor
b. Beta z2 zreceptor d. z Delta zreceptor
ANS: z A
Stimulation zof zthe zbeta-1 zreceptors zresults zin ztachycardia, zan zincreased zpotential zfor
zarrhythmias, zand zan zincreased zcardiac zoutput. zIn zadministering zdrugs zto zthe zpulmonary zsystem,
zstimulation zof zthe zbeta-1 zsites zis znot zdesired. zHowever, zmost zrespiratory zpharmacologic zagents
zhave zsome zbeta-1 zstimulatory zeffect.
PTS: z 1
3. Stimulation zof zthe zbeta z2 zreceptors zcauses z
a. peripheral zvasoconstriction zand zmild zbronchoconstriction zin zthe zlungs.
b. tachycardia, zan zincreased zpotential zfor zarrhythmias, zand zan zincreased zcardiac zoutput.
c. bronchodilation.
d. peripheral zvasodilation, zbradycardia, zand zdecreased zcardiac zoutput.
ANS: z C
Stimulation zof zthe zbeta-2 zreceptors zin zthe zlungs zcauses zbronchodilation.
PTS: z 1
4. Acetylcholine zstimulates z
a. the zVagus znerve.
b. the zadrenergic zreceptors.
c. the zsympathetic znervous zsystem.
d. the zcholinergic zreceptors.
ANS: z D
Acetylcholine zstimulates zthe zcholinergic zreceptors.
PTS: z 1
5. What zimmunoglobulin zantibody zsensitizes zthe zmast zcell?
a. Leukotrienes c. Histamine
, b. IgE d. z Prostaglandins
ANS: z B
The zIgE z(reagin) zantibodies zsensitize zthe zmast zcell. zRepeated zexposure zto zthe zantigen zcauses zthe
zdegranulation zof zthe zmast zcell.
PTS: z 1
6. Which zof zthe zfollowing zis zcaused zby zhistamine zrelease zfrom zthe zmast zcells?
I. Bronchodilation
II. Increased zbronchial zgland zsecretion
III. Increased zamount zof zmucus zpresent zin zthe zairways
a. I zand zII zonly c. III zonly
b. II zand zIII zonly d. z z I, zII, zIII
ANS: z B
Histamine zis zalso za zpotent zbronchoconstrictor. zIn zaddition zto zits zbronchoconstrictive zactivity, zhistamine
II) zincreases zbronchial zgland zsecretion, zcausing zIII) zan zincrease zin zthe zamount zof zmucus
zpresent zin zthe zairways. zHistamine zmay zalso zhave zan zeffect zon zvascular zpermeability
zsimilar zto zthe zeffect zof- zSRS-A.
PTS: z 1
7. A zsympathomimetic zdrug zwould zcause z
a. bronchodilation. c. Histamine zrelease.
b. bronchoconstriction. d. z Vagus znerve zstimulation.
ANS: z A
A zsympathomimetic zdrug zwould zcause zbronchodilation. zSympathomimetic zagents zare zthe zdrugs zmost
zcommonly zused zto zreverse zbronchospasm.
PTS: z 1
8. Stimulation zof zthe zsympathetic znervous zsystem zcauses z
a. vascular zpermeability. c. bronchodilation.
b. decreased zblood zpressure. d. z bronchoconstriction.
ANS: z C
Sympathetic znervous zsystem zstimulation zcauses zbronchodilation.
PTS: z 1
9. Which zof zthe zfollowing zwould zNOT zcause za zbronchospasm zor zbronchoconstriction?
a. Leukotrienes c. Histamine
b. Beta z1 zreceptors d. z Prostaglandins
ANS: z B
Beta-1 zreceptors zwould znot zcause za zbronchospasm zor zbronchoconstriction. zLeukotrienes zare
zone zof zmany zchemical zmediators zreleased zby zthe zmast zcells. zLeukotrienes zcause za zdirect,
zstrong zbronchoconstriction. zHistamine zis zalso za zpotent zbronchoconstrictor. zProstaglandins zcause
za zstrong zbronchospasm, zespecially zin zasthmatic zpatients.
PTS: z 1
