A client asks a nurse about the role of bronchodilators in asthma treatment. How should the nurse explain their function?
"Bronchodilators are used to reduce airway inflammation in the lungs."
"They help relax the muscles around your airways, making it easier to breathe."
"Bronchodilators prevent asthma symptoms from occurring in the first place."
"They are used to treat allergic reactions related to asthma."
The Correct Answer is B
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.
