The nurse is planning education for a client on their new inhaled corticosteroid. Which information should the nurse plan to include in this client's education? Select all that apply.

A. "This inhaled corticosteroid should be used to treat an acute asthma attack.": Inhaled corticosteroids are maintenance medications used for long-term control of asthma. They are not rescue medications and will not provide immediate relief during an acute asthma attack. B. "You may notice dry mouth and throat irritation while using this medication.": Dry mouth and throat irritation are common local side effects of inhaled corticosteroids due to their anti-inflammatory action on airway mucosa, making this important to include in patient education. C. "Pay special attention to your dental hygiene while prescribed this medication.": Good oral hygiene is crucial because inhaled corticosteroids can increase the risk of oral candidiasis and other oral infections. Educating the client on brushing, flossing, and routine dental care helps reduce these risks. D. "After administration of the medication, rinse your mouth with water and spit.": Rinsing the mouth after inhalation helps remove residual medication, reducing the risk of oral fungal infections and irritation, which is an essential preventive measure. E. "White patches in your mouth are expected when you take this medication.": White patches, or oral thrush, are not expected but are a potential adverse effect. The client should be advised to report these signs rather than assume they are normal.
