Answer Key Asthma Questions
1.) A child enters the office with the following symptoms, which symptom would NOT be associated with an asthma diagnosis?
c. stridor
Asthma symptoms are expiratory wheezing, chest tightness, increased heart rate, shortness of breath, anxiousness, difficulty speaking in full sentences, to name a few. Stridor is most likely associated with an upper airway obstruction or croup.
2.) What is the main function of the lungs?
b. supply adequate oxygen to the blood and remove carbon dioxide from the blood
The lungs supply oxygen to the blood and remove carbon dioxide through the processes of ventilation and perfusion. The main function of the heart is to pump blood throughout the body via the circulatory system. The kidneys are responsible for excreting waste through the production of urine.
3.) What is true of childhood asthma?
c. It presents more severely in smaller children due to their smaller airway diameter.
Childhood asthma is the most prevalent chronic childhood disease. It is a type I hypersensitivity reaction. The presentation of bronchoconstriction and airway hyperresponsiveness is reversible.
4.) Which immunoglobulin mediates the asthmatic response?
d. IgE
IgE is the immunoglobulin responsible for allergy-related immune responses, including asthma. IgG protects against viral and bacterial infections. IgM is the first responder to new infections in the body. IgA are most commonly found in mucous membranes.
5.) True or False: The early asthmatic response is categorized by airway hyperresponsiveness and manifests 4-8 hours after introduction to antigen.
b. False
The early asthmatic response is characterized by acute bronchoconstriction that peaks at 30 minutes and lasts from 1-3 hours. The late asthmatic response is categorized by airway hyperresponsiveness and manifests 4-8 hours after introduction to antigen.
