A nurse is providing teaching about cough etiquette to a client who has influenza. Which of the following instructions should the nurse include in the teaching?

A. "Cover your nose and mouth with a tissue when coughing.": Covering both the nose and mouth with a tissue prevents respiratory droplets from spreading into the environment, reducing transmission of influenza to others. Proper disposal of the tissue and hand hygiene should follow. B. "If you are coughing frequently, you should wear gloves when preparing meals.": Gloves are not a primary measure for cough etiquette. Hand hygiene and avoiding food preparation while symptomatic are more effective in preventing the spread of influenza. C. "Stay 2 feet away from others when coughing.": Droplet precautions for influenza recommend maintaining at least 3 feet of distance, and ideally up to 6 feet, to prevent exposure. Two feet is inadequate to protect others from respiratory droplets. D. "Turn your head away when coughing.": Turning the head alone does not sufficiently contain respiratory secretions. Droplets can still disperse into the air, so using a tissue or the elbow crease is more effective.
