Based on the severity of Sunita's asthma, which of the following treatment options is appropriate?

The correct answer suggests that a comprehensive approach to treating Sunita's asthma is necessary, which can involve various treatment options depending on the severity of her condition. Asthma management often requires a tiered strategy that adapts to the patient's specific needs.

Using solely a rescue inhaler may not be sufficient for individuals with moderate to severe asthma, as they may experience frequent symptoms that necessitate more consistent management. Long-term systemic corticosteroids are generally reserved for cases where asthma is significantly affecting the patient's quality of life or when inhaled options are inadequate. Low-dose inhaled corticosteroids are commonly prescribed for individuals managing persistent asthma as they help reduce inflammation and improve overall control.

Thus, suggesting that all mentioned treatments can be appropriate highlights the importance of tailoring asthma management. Depending on the severity and frequency of asthma symptoms, a combination of these options may be required to achieve optimal control and minimize exacerbations. This multifaceted approach ensures that patients receive the right balance of quick-relief and long-term control medications, particularly in cases of more severe or persistent asthma.
