A nurse is reinforcing teaching with a client who is to start taking montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?

A. "I'll use this medication when I get an asthma attack.": Montelukast is a maintenance medication, not a rescue inhaler. It is taken daily to prevent asthma symptoms rather than to treat acute attacks, so using it only during an attack is incorrect. B. "I'll take this medication once a day in the evening.": Montelukast is typically prescribed to be taken once daily in the evening. Taking it in the evening helps prevent nighttime asthma symptoms and aligns with the drug’s optimal effectiveness. C. "I'll decrease my sodium intake while I'm taking this medication.": Montelukast does not require sodium restriction. Dietary sodium does not affect the medication’s action or safety. D. "I'll rinse my mouth after taking this medication.": Rinsing the mouth is important after using inhaled corticosteroids to prevent oral thrush. Montelukast is an oral tablet or chewable, so mouth rinsing is not necessary.
