507: Advanced Pathophysiology Midterm
exam with straight answers for a guaranteed
pass.
Question 1
Asthma
Chronic disease due to bronchoconstriction and an excessive inflammatory
response in the bronchioles
Question 2
What are 5 s/s of asthma
Coughing
Wheezing
Shortness of breath
Rapid breathing
Chest tightness
Question 3
Pathophysiology of asthma (5)
-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 4
Bronchioles
Smaller passageways that originate from the bronchi that become the alveoli
,Question 5
3 layers of the bronchioles
Innermost layer
Middle layer – lamina propria
Outermost layer
Question 6
Lamina propria
The middle layer of the bronchioles
Question 7
Structure of the lamina propria
Embedded with connective tissue cells and immune cells
Question 8
Purpose of the lamina propria
White blood cells are present to help protect the airways
Question 9
How does the lamina propria effect the lungs in regards to asthma
The WBCs protective feature goes into overdrive causing an inflammatory
response that damages host tissue
Question 10
What does the innermost layer of the bronchioles contain
Columnar epithelial ells and mucus producing goblet cells
, Question 11
What does the outermost layer of the bronchioles contain
Smooth muscle cells
Question 12
What does the outermost layer of the bronchioles do
Control the airways ability to constrict and dilate
Question 13
Alveolar hyperinflation
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 14
How does hyperinflation occur?
The ongoing inflammatory process of asthma produces mucus and pus plug
that the bronchial walls collapse around
Question 15
Effect of hyperinflation of the alveolar
-expanded thorax and hypercapnia (retention of CO2)
- respiratory acidosis
What are two anticholinergic drugs used for asthma
Tiotropium and ipratropium
