"Asthma is primarily caused by bacterial infections in the lungs."
"Genetics do not play a role in the development of asthma."
"Exposure to environmental allergens and irritants can contribute to the development of asthma."
"Asthma is solely triggered by emotional stress and anxiety."
The Correct Answer is C
A) Incorrect. Bacterial infections are not the primary cause of asthma; it is more related to inflammation and airway hyperreactivity.
B) Incorrect. Genetics can indeed play a role in the development of asthma.

Correct Answer is B
Explanation
A) Incorrect. Reducing airway inflammation is the primary function of inhaled corticosteroids, not bronchodilators.
B) Correct. Bronchodilators, such as beta-agonists, help relax the smooth muscles surrounding the airways, which can improve airflow and relieve bronchoconstriction in asthma.
C) Incorrect. Bronchodilators primarily provide quick relief during asthma attacks but do not prevent asthma symptoms over the long term.
D) Incorrect. Bronchodilators are not used to treat allergic reactions; they are used to relieve acute bronchoconstriction associated with asthma.
Correct Answer is C
Explanation
A) Incorrect. A decrease in peak flow measurements typically indicates worsening asthma, not improved control.
B) Incorrect. While an increase in rescue inhaler use may be necessary during an exacerbation, it does not address the underlying issue of worsening asthma.
C) Correct. A decrease in peak flow measurements is a sign of declining lung function, suggesting that asthma may be worsening. Following the asthma action plan is essential in this situation.
D) Incorrect. Peak flow measurements are a valuable tool in asthma management and are related to monitoring and controlling asthma symptoms.
