In an acute asthma exacerbation, which options are commonly used as part of treatment?

• A. Oral corticosteroids
• B. Duo-Neb
• C. Oxygen to maintain sat >93%
• D. All of the above

Answer: (D)

In an acute asthma flare, treatment targets quick bronchodilation, control of inflammation, and adequate oxygenation. Oral corticosteroids are given to dampen the airway inflammation that drives the flare; they accelerate recovery and reduce the risk of relapse. Inhaled bronchodilators provide rapid relief of bronchospasm, and using a nebulized combination of albuterol plus ipratropium (the Duo-Neb) can offer additional bronchodilation, especially if symptoms are not fully controlled after initial bronchodilator therapy. Oxygen is used to correct hypoxemia and ensure sufficient oxygen delivery to tissues, with a target that keeps the oxygen saturation in a safe range (often around the low-to-mid 90s, depending on guidelines). Taken together, these measures address inflammation, bronchospasm, and oxygenation, which is why all of them are commonly used in acute asthma management.
