GMS 6530 Respiratory exam with correct
answers
VRG - correct answer✔✔- generates rhythm
- set at 12/min
DRG - correct answer✔✔- modifies rate & depth
PRG - correct answer✔✔- adapts breathing to special circumstances
- sleep
- exercise
- talking
- emotional responses
Central chemoreceptors - correct answer✔✔- pH in CSF
Peripheral chemoreceptor - correct answer✔✔- O2 & CO2
- carotid & arotic bodies
Stretch receptors - correct answer✔✔- found in bronchi & bronchioles
- sensitive to lung inflation
Irritant receptors - correct answer✔✔- nerve endings in epithelial cells of airway
- sense smoke, dust, pollen, chemical fumes, cold air, mucus
- trigger bronchoconstriction, shallow breathing, breath-holding, coughing
, IRDS - correct answer✔✔- infant respiratory distress syndrome
- premies lacking surfactant
- < 37 weeks
Asthma - correct answer✔✔- inflammatory disease with bronchial hyper-reactivity
- histamines & proteases released immediately
- leukotrienes & prostaglandins released after minutes
- interleukins released after hours
Inhalation therapy - correct answer✔✔- instant relief
- delivers drug directly to site of action
- little toxicity
- 80-90% stays in mouth/pharynx (can cause thrush)
- rescue and maintenance
Oral therapy - correct answer✔✔- longer onset & duration of action
- frequent side effects
- maintenance only
beta II - correct answer✔✔- bronchodilation
Muscarinic - correct answer✔✔- bronchoconstriction
Autocoids (relaesed in asthmatic attack) - correct answer✔✔- histamines, leukotrienes,
adenosine
