Q1 QUESTION 1 OF 167
Page 1
,Asthma
CORRECT ANSWER
Chronic disease due to bronchoconstriction and an excessive inflammatory response in the bronchioles
RATIONALE
Asthma results from a complex interplay of bronchoconstriction and inflammation, leading to airway hyperreactivity and obstruction, which impairs airflow
and oxygen exchange. Recognizing asthma as a chronic inflammatory disease is crucial for effective management and treatment strategies.
Q2 QUESTION 2 OF 167
What are 5 s/s of asthma
CORRECT ANSWER
coughing
wheezing
shortness of breath
rapid breathing
chest tightness
RATIONALE
Asthma exacerbations lead to bronchoconstriction and airway inflammation, resulting in classic symptoms such as wheezing, coughing, and shortness of
breath due to reduced airflow. Rapid breathing and chest tightness reflect the body's compensatory mechanisms in response to hypoxia and increased
respiratory effort.
Q3 QUESTION 3 OF 167
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
RATIONALE
Airway inflammation and bronchial smooth muscle hypertrophy lead to bronchoconstriction and excess mucus production, resulting in airflow obstruction
and decreased alveolar ventilation. This pathophysiological cascade illustrates the complex interplay of inflammatory and obstructive processes in asthma.
Q4 QUESTION 4 OF 167
Bronchioles
CORRECT ANSWER
smaller passageways that originate from the bronchi that become the alveoli
Page 2
, RATIONALE
Bronchioles are the tertiary branches of the bronchial tree that progressively narrow and lack cartilage, leading to the alveolar ducts and alveoli where gas
exchange occurs. Their structure facilitates efficient airflow regulation and maximizes surface area for oxygen and carbon dioxide exchange in the lungs.
Q5 QUESTION 5 OF 167
3 layers of the bronchioles
CORRECT ANSWER
innermost layer
middle layer - lamina propria
outermost layer
RATIONALE
Bronchioles are structured with an innermost epithelium providing a protective barrier, a middle lamina propria containing connective tissue and smooth
muscle for flexibility and support, and an outermost layer of adventitia anchoring the bronchioles to surrounding tissues. This tri-layer architecture is crucial
for maintaining airway patency and facilitating efficient airflow dynamics in the respiratory system.
Q6 QUESTION 6 OF 167
lamina propria
CORRECT ANSWER
the middle layer of the bronchioles
RATIONALE
The lamina propria provides structural support to the bronchioles, containing connective tissue, blood vessels, and immune cells that facilitate gas exchange
and protect against pathogens. Its location as the middle layer is crucial for maintaining the integrity and function of the respiratory tract.
Q7 QUESTION 7 OF 167
structure of the lamina propria
CORRECT ANSWER
embedded with connective tissue cells and immune cells
RATIONALE
Lamina propria consists of loose connective tissue that supports epithelial layers and houses various immune cells, facilitating both structural integrity and
immune response. This architecture is essential for maintaining mucosal barrier function and responding to pathogens.
Q8 QUESTION 8 OF 167
purpose of the lamina propria
CORRECT ANSWER
white blood cells are present to help protect the airways
Page 3
, RATIONALE
Lamina propria contains immune cells, including white blood cells, which provide a first line of defense against pathogens entering the respiratory tract. This
layer plays a crucial role in maintaining airway integrity and preventing infections.
Q9 QUESTION 9 OF 167
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
RATIONALE
Inflammation in asthma results from the infiltration of white blood cells in the lamina propria, leading to an exaggerated immune response that damages
airway tissues and contributes to bronchoconstriction and mucus hypersecretion. This process underscores the role of the lamina propria in modulating
airway inflammation and hyperreactivity in asthma pathology.
Q10 QUESTION 10 OF 167
What are two anticholinergic drugs used for asthma
CORRECT ANSWER
tiotropium and ipratropium
RATIONALE
Anticholinergic drugs like tiotropium and ipratropium act by blocking muscarinic receptors in the airways, leading to bronchodilation and improved airflow
in patients with asthma. This mechanism helps reduce bronchoconstriction and mucus secretion, enhancing respiratory function.
Q11 QUESTION 11 OF 167
High output failure
CORRECT ANSWER
inability of the heart to pump sufficient amounts of blood to meet the circulatory needs of the body despite normal blood volume and cardiac
contractility
RATIONALE
High output failure occurs when the heart cannot adequately supply blood to meet the body's metabolic demands despite having normal volume and
contractility, often seen in conditions like sepsis or hyperthyroidism where systemic demands exceed cardiac capacity. This distinction emphasizes the
heart's role in responding to physiological stressors rather than merely reflecting volume status or contractile strength.
Q12 QUESTION 12 OF 167
What effects amount of water and solute reabsorption
CORRECT ANSWER
ADH and aldosterone
