Asthma - CORRECT ANSWER Chronic disease due to bronchoconstriction and an
excessive inflammatory response in the bronchioles



QUESTION : What are 5 s/s of asthma - CORRECT ANSWER coughing

wheezing
shortness of breath
rapid breathing
chest tightness



QUESTION : 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



QUESTION : Bronchioles - CORRECT ANSWER smaller passageways that originate
from the bronchi that become the alveoli

QUESTION : lamina propria - CORRECT ANSWER the middle layer of the bronchioles



QUESTION : structure of the lamina propria - CORRECT ANSWER embedded with
connective tissue cells and immune cells



QUESTION : purpose of the lamina propria - CORRECT ANSWER white blood cells
are present to help protect the airways



QUESTION : 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



QUESTION : What does the innermost layer of the bronchioles contain - CORRECT
ANSWER columnar epithelial ells and mucus producing goblet cells



QUESTION : What does the outermost layer of the bronchioles contain - CORRECT
ANSWER smooth muscle cells



QUESTION : what does the outermost layer of the bronchioles do - CORRECT ANSWER
control the airways ability to constrict and dilate



QUESTION : 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



QUESTION : how does hyperinflation occur? - CORRECT ANSWER the ongoing
inflammatory process of asthma produces mucus and pus plug that the bronchial walls
collapse around

QUESTION : Effect of hyperinflation of the alveolar - CORRECT ANSWER -expanded
thorax and hypercapnia (retention of CO2)
- respiratory acidosis



QUESTION : What are two anticholinergic drugs used for asthma - CORRECT ANSWER
tiotropium and ipratropium



QUESTION : What do anticholinergics do in the lungs? - CORRECT ANSWER These
drugs block the effects of the parasympathetic nervous system
- increasing bronchodilation



QUESTION : 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 receptors of the respiratory tract to cause bronchial constriction =
decreased airflow


- blocking the cholinergic receptors prevents acetylcholine binding preventing the bronchial
constriction



QUESTION : bronchitis - CORRECT ANSWER inflammation of the bronchial tubes



QUESTION : 3 characteristics of bronchitis - CORRECT ANSWER bronchial
inflammation
hypersecretion of mucus
chronic productive cough for at least 3 consecutive months for at least 2 successive years



QUESTION : Perfusion - CORRECT ANSWER The supply of oxygen to and removal of
wastes from the cells and tissues of the body as a result of the flow of blood through the
capillaries.
