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?

Rationale: A. Check the pulse after medication administration is incorrect because inhaled beclomethasone is a corticosteroid, not a bronchodilator. Monitoring pulse is primarily relevant for short-acting beta-agonists (SABAs) like albuterol, which can cause tachycardia, palpitations, or tremors. Beclomethasone works by reducing airway inflammation and does not have significant cardiovascular stimulant effects, so pulse monitoring is not necessary. B. Take the medication with meals is incorrect because inhaled corticosteroids are administered via inhalation, not orally. Food does not affect the efficacy or absorption of the medication. Oral corticosteroids sometimes require taking with meals to reduce gastrointestinal irritation, but this does not apply to inhaled forms. C. Limit caffeine intake is incorrect because inhaled corticosteroids do not have stimulant properties. Caffeine restriction is relevant for medications such as theophylline, which is a bronchodilator and central nervous system stimulant. Beclomethasone does not affect heart rate or cause jitteriness, so caffeine intake does not need to be modified. D. Rinse the mouth after administration is correct because inhaled corticosteroids can cause local adverse effects, including oral thrush (candidiasis), hoarseness, and throat irritation. These occur because some medication can remain in the oropharynx after inhalation. Rinsing the mouth and gargling with water after each dose helps remove residual medication, reducing the risk of fungal infection and maintaining oral and throat health. Using a spacer with a metered-dose inhaler can also further minimize deposition of medication in the mouth and throat.
