CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS)
1. What is asthma?
Correct Answer: Chronic disease due to bronchoconstriction and an excessive
inflammatory response in the bronchioles
Rationale: This question tests knowledge of the definition of asthma. Asthma is a
chronic inflammatory disease of the airways characterized by bronchoconstriction,
airway hyper-reactivity, and an excessive inflammatory response in the
bronchioles. The detailed rationale should explain that asthma causes reversible
airflow obstruction and that it involves both inflammation and
bronchoconstriction, which guide treatment with anti-inflammatory agents and
bronchodilators.
2. What are 5 signs and symptoms of asthma?
Correct Answer: Coughing, wheezing, shortness of breath, rapid breathing, chest
tightness
Rationale: This question tests knowledge of the clinical manifestations of asthma.
The detailed rationale should explain that coughing (especially at night or with
exercise), wheezing (a high-pitched whistling sound on expiration), shortness of
breath, rapid breathing (tachypnea), and chest tightness are the classic signs and
symptoms of asthma. These manifestations result from bronchoconstriction,
airway inflammation, and increased mucus production.
3. What is the pathophysiology of asthma?
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
,Rationale: This question tests knowledge of the pathophysiology of asthma. The
detailed rationale should explain that airway inflammation, bronchial hyper-
reactivity, and smooth muscle spasm cause narrowing of the airways; excess
mucus production and accumulation further obstruct airflow; hypertrophy of
bronchial smooth muscle contributes to chronic airway narrowing; airflow
obstruction impairs expiration; and decreased alveolar ventilation leads to
hypoxemia and hypercapnia.
4. What are bronchioles?
Correct Answer: Smaller passageways that originate from the bronchi that
become the alveoli
Rationale: This question tests knowledge of the anatomy of the bronchioles. The
detailed rationale should explain that bronchioles are smaller passageways that
branch from the bronchi and lead to the alveoli, where gas exchange occurs.
Bronchioles are surrounded by smooth muscle that can constrict or dilate, and
inflammation and mucus accumulation in the bronchioles are central to asthma
and bronchitis.
5. What are the 3 layers of the bronchioles?
Correct Answer: Innermost layer, middle layer (lamina propria), outermost layer
Rationale: This question tests knowledge of the layers of the bronchioles. The
detailed rationale should explain that the innermost layer contains columnar
epithelial cells and mucus-producing goblet cells, the middle layer (lamina
propria) contains connective tissue cells and immune cells, and the outermost
layer contains smooth muscle cells that control the airway's ability to constrict and
dilate.
6. What is the lamina propria?
Correct Answer: The middle layer of the bronchioles
Rationale: This question tests knowledge of the lamina propria. The detailed
rationale should explain that the lamina propria is the middle layer of the
, bronchioles, embedded with connective tissue cells and immune cells. White
blood cells are present in the lamina propria to help protect the airways.
7. What is the structure of the lamina propria?
Correct Answer: Embedded with connective tissue cells and immune cells
Rationale: This question tests knowledge of the structure of the lamina propria.
The detailed rationale should explain that the lamina propria contains connective
tissue cells and immune cells, including white blood cells that protect the airways.
In asthma, the immune cells in the lamina propria release inflammatory mediators
that cause bronchoconstriction and mucus production.
8. What is the purpose of the lamina propria?
Correct Answer: White blood cells are present to help protect the airways
Rationale: This question tests knowledge of the purpose of the lamina propria.
The detailed rationale should explain that the lamina propria contains white blood
cells that protect the airways from pathogens and irritants. In asthma, this
protective mechanism becomes overactive and causes inflammation that damages
host tissue.
9. How does the lamina propria affect the lungs in regards to asthma?
Correct Answer: The WBCs' protective feature goes into overdrive causing an
inflammatory response that damages host tissue
Rationale: This question tests knowledge of the role of the lamina propria in
asthma. The detailed rationale should explain that in asthma, the white blood
cells in the lamina propria release inflammatory mediators that cause
bronchoconstriction, mucus production, and airway damage. This inflammatory
response is the target of corticosteroid therapy.
10.What does the innermost layer of the bronchioles contain?
Correct Answer: Columnar epithelial cells and mucus-producing goblet cells
Rationale: This question tests knowledge of the innermost layer of the
bronchioles. The detailed rationale should explain that the innermost layer
