A nurse is caring for a child who has asthma and a prescription for montelukast granules. Which of the following instructions should the nurse provide the client's parent on administering the medication?

A. Administer the granules mixed with 20 oz of water: Montelukast granules should be mixed with a small amount of soft food (e.g., applesauce, carrots, rice, or ice cream) or administered directly in the mouth. Mixing with a large volume of water is not recommended and may affect dosing accuracy. B. Give the medication in the morning daily: Montelukast is usually given in the evening for persistent asthma to align with circadian patterns of asthma symptoms. Morning administration may reduce its effectiveness in controlling nighttime symptoms. C. Give the medication at the onset of wheezing: Montelukast is not a rescue medication. It works as a controller to prevent asthma symptoms, not to relieve acute wheezing or asthma attacks. D. Administer the medication 2 hr before exercise: Montelukast granules can be used to prevent exercise-induced bronchoconstriction. Giving the medication at least 2 hours before physical activity allows it to reach effective levels in the body, reducing the likelihood of exercise-triggered asthma symptoms.
