Asthma - CORRECT ANSWER >>>>Chronic disease due to
bronchoconstriction and an excessive inflammatory response in
the bronchioles
What are 5 s/s of asthma - CORRECT ANSWER >>>>coughing
wheezing
shortness of breath
rapid breathing
chest tightness
Pathophysiology of asthma (5) - CORRECT ANSWER >>>>-airway
inflammation, bronchial hyper-reactivity and smooth muscle
spasm
-excess mucus production and accumulation
-hypertrophy of bronchial smooth muscle
-airflow obstruction
-decreased alveolar ventilation
,2|Page
Bronchioles - CORRECT ANSWER >>>>smaller passageways that
originate from the bronchi that become the alveoli
3 layers of the bronchioles - CORRECT ANSWER >>>>innermost
layer
middle layer - lamina propria
outermost layer
lamina propria - CORRECT ANSWER >>>>the middle layer of the
bronchioles
structure of the lamina propria - CORRECT ANSWER
>>>>embedded with connective tissue cells and immune cells
purpose of the lamina propria - CORRECT ANSWER >>>>white
blood cells are present to help protect the airways
How does the lamina propria effect the lungs in regards to
asthma - CORRECT ANSWER >>>>the WBCs protective feature
goes into overdrive causing an inflammatory response that
damages host tissue
What does the innermost layer of the bronchioles contain -
CORRECT ANSWER >>>>columnar epithelial ells and mucus
producing goblet cells
What does the outermost layer of the bronchioles contain -
CORRECT ANSWER >>>>smooth muscle cells
, 3|Page
what does the outermost layer of the bronchioles do - CORRECT
ANSWER >>>>control the airways ability to constrict and dilate
alveolar hyperinflation - CORRECT ANSWER >>>>When air is
unable to move out of the alveolar like it should due to
bronchial walls collapsing around possible mucus plug thus
trapping air inside
how does hyperinflation occur? - CORRECT ANSWER >>>>the
ongoing inflammatory process of asthma produces mucus and
pus plug that the bronchial walls collapse around
Effect of hyperinflation of the alveolar - CORRECT ANSWER
>>>>-expanded thorax and hypercapnia (retention of CO2)
- respiratory acidosis
What are two anticholinergic drugs used for asthma - CORRECT
ANSWER >>>>tiotropium and ipratropium
What do anticholinergics do in the lungs? - CORRECT ANSWER
>>>>These drugs block the effects of the parasympathetic
nervous system
- increasing bronchodilation
MOA of anticholinergic drugs for asthma - CORRECT ANSWER
>>>>the parasympathetic system is stimulated by the vagal
nerve to release acetylcholine which binds to the cholinergic
