UPDATED Study ACTUAL QUESTIONS
AND CORRECT ANSWERS
Name the five characteristics for Moderate Persistent Asthma (adult) - CORRECT
ANSWER Daily symptoms
Daily use of inhaler
Nighttime awakenings more than once/week, but not nightly
Moderate limitation to activities
Lung function is < predicted
Define Asthma - CORRECT ANSWER Asthma is a chronic, inflammatory,
obstructive, non-contagious airway disease with varying levels of severity.
Explain in relation to inhalation, and exhalation what the smooth muscle is doing. -
CORRECT ANSWER On inhalation the smooth muscle relaxes allowing the air to
enter the alveoli, and on exhalation the smooth muscle contracts.
What is the main cell type in the mucosa ? - CORRECT ANSWER Pseudostratified,
ciliated columnar epithelium
Which type of cells are responsible for secreting Mucous? - CORRECT
ANSWER Goblet Cells
What does the submucosal layer contain? - CORRECT ANSWER Bronchial glands
which are the major source of respiratory tract secretions.
(An increase in bronchial glands = increase in secretion production in the airways)
Mast Cells.
When the mast cells are stimulated they excrete mediators such as? - CORRECT
ANSWER Histamine, Leukotrienes
, Eosinophilia - CORRECT ANSWER Increase in the number of eosinophils in the
blood, occurring in response to some allergens, drugs, and parasites, and in some types of
leukemia
Histamines cause what in the airways? - CORRECT ANSWER The histamines cause
constriction of the smooth muscle that surround the airway, which leads to bronchospasm and
SOB.
It also contributes to the development of inflammation by increasing the permeability of
blood vessels.
Leukotrienes cause what to happen in the airways? - CORRECT
ANSWER Bronchoconstriction, and they also promote inflammation by attracting and
activating eosinophils
Three primary changes that occur during an asthma attack? - CORRECT
ANSWER Bronchial smooth muscle constriction
Mucosal inflammation (edema)
Hypersecretion of mucus
Bronchoconstriction is due to what? - CORRECT ANSWER Stimulus such as dust,
cold air, animal dander etc.
What is the process of mucosal inflammation? - CORRECT ANSWER Goblet cells
increase, and bronchial glands enlarge which produce excessive mucus causing mucus
plugging.
Mucosa is infiltrated with eosinophils, such as lymphocytes and mast cells, causing tissue to
become swollen.
Cilia become damaged and basement membrane of the mucosa becomes thicker than normal.
Inflammation leads to what 3 conditions? - CORRECT ANSWER airway obstruction,
air trapping, and alveolar hyperinflation
