Kennedy with acute asthma showing inspiratory and expiratory wheezes and a decreased forced expiratory volume should be treated with which of the following classes of medication right away?
A. Beta-adrenergic blockers
B. Bronchodilators
C. Inhaled steroids
D. Oral steroids
Correct Answer: B. Bronchodilators
Bronchodilators are the first line of treatment for asthma because broncho-constriction is the cause of reduced airflow.
Option A: Beta-adrenergic blockers aren’t used to treat asthma and can cause bronchoconstriction.
Option C: Inhaled steroids are not ideal for emergency cases because of their slow onset.
Option D: Oral steroids may be given to reduce the inflammation but aren’t used for emergency relief.
