A client with chronic asthma receives a prescription for montelukast, a leukotriene modifier. Which statement by the client indicates to the nurse that medication teaching was effective?

Rationale: Option C is correct because montelukast is a maintenance medication for asthma and needs to be taken regularly to control symptoms. Taking the tablet every evening helps maintain a consistent level of the drug in the body, reducing inflammation and preventing asthma attacks. Options A, B, and D are incorrect because montelukast is not a rescue medication for immediate relief during an asthma attack, it does not replace the need for using inhalers twice a day, and it does not provide immediate relief during an asthma attack.
