A nurse is providing teaching to a client who has asthma and a new prescription for inhaled beclomethasone. Which of the following instructions should the nurse provide?

A. Beclomethasone, an inhaled corticosteroid, does not need to be taken with meals, as it is not associated with gastrointestinal upset. B. Checking the pulse is recommended with beta-agonist bronchodilators (like albuterol), which can cause tachycardia — not necessary with beclomethasone. C. Rinsing the mouth after administration helps prevent oral candidiasis (thrush), a common side effect of inhaled corticosteroids like beclomethasone. D. Limiting caffeine intake may be advised with certain asthma medications like theophylline, but it is not relevant for beclomethasone.
