When entering a client's room, the nurse observes the client holding up an arm and coughing non-productively into the upper sleeve. Which action should the nurse take?

A. Provide a box of tissues for the client to use when coughing is a helpful action for promoting hygiene and comfort. However, this does not address the potential risk of infection transmission to staff and others in the room. B. Obtain face masks for staff to wear upon entering the room is the most appropriate action. The client is coughing, and non-productive coughing can still release droplets that may carry infectious agents. Wearing face masks helps protect staff and other individuals from potential exposure to airborne pathogens. C. Assist the client in changing into a fresh hospital gown is a considerate action but does not directly address the immediate concern of infection control. The priority here is preventing the spread of potential infectious particles. D. Teach the client to cover the mouth with hands when coughing is incorrect. The client should cover their cough with their elbow or a tissue, not with their hands, to prevent spreading germs. Teaching this technique is important but does not address the immediate need for protective measures for staff.
