Which of the following is NOT an appropriate nonpharmacologic recommendation for a cough?

A. Take nonmedicated lozenges or candies: Sucking on lozenges or hard candies can help soothe the throat and reduce irritation that triggers coughing. This is a safe and commonly recommended nonpharmacologic measure for managing mild cough. B. Use a humidifier or vaporizer: Humidifiers and vaporizers add moisture to the air, which can ease throat and airway irritation. This can help reduce coughing, especially in dry environments, making it an effective non-drug intervention. C. Get adequate rest: Rest supports the immune system and allows the body to recover from infections or irritants causing the cough. Adequate rest is a foundational nonpharmacologic approach for symptomatic relief and overall recovery. D. Limit water intake: Reducing fluid intake can worsen throat and airway irritation, leading to more frequent coughing. Adequate hydration thins mucus and helps soothe the respiratory tract, limiting water is not recommended.
