Allergies and Asthma in Children
Allergies and Asthma in Children ( 15 Questions)
Which of the following statements by the nurse is correct regarding the pathophysiology of asthma in children?
Asthma is not characterized by a lack of airway sensitivity and hyperresponsiveness. In fact, asthma is often associated with increased airway sensitivity and hyperresponsiveness. This heightened reactivity of the airways is a hallmark of asthma.
In asthma, airway muscles do not relax and widen during an episode. Instead, they constrict or tighten, leading to airway obstruction and making breathing more difficult. This bronchoconstriction is a key feature of asthma.
The correct answer is C. Chronic inflammation of the airways in asthma does lead to increased airway sensitivity and hyperresponsiveness. This chronic inflammation makes the airways more reactive to various triggers, including allergens, and contributes to the characteristic symptoms of asthma.
Exposure to allergens or irritants in asthma does have an impact on airway constriction. In individuals with asthma, exposure to allergens or irritants can trigger an inflammatory response in the airways, leading to increased bronchoconstriction and worsening symptoms.
Choice A rationale:
Asthma is not characterized by a lack of airway sensitivity and hyperresponsiveness.
In fact, asthma is often associated with increased airway sensitivity and hyperresponsiveness.
This heightened reactivity of the airways is a hallmark of asthma.
Choice B rationale:
In asthma, airway muscles do not relax and widen during an episode.
Instead, they constrict or tighten, leading to airway obstruction and making breathing more difficult.
This bronchoconstriction is a key feature of asthma.
Choice D rationale:
Exposure to allergens or irritants in asthma does have an impact on airway constriction.
In individuals with asthma, exposure to allergens or irritants can trigger an inflammatory response in the airways, leading to increased bronchoconstriction and worsening symptoms.
Choice C rationale:
The correct answer is C.
Chronic inflammation of the airways in asthma does lead to increased airway sensitivity and hyperresponsiveness.
This chronic inflammation makes the airways more reactive to various triggers, including allergens, and contributes to the characteristic symptoms of asthma.
