A home health nurse is teaching about oral care to the family of a client who is in a coma. Which of the following tasks should the nurse instruct the family to perform first?

A. Place the client in a side-lying position: Positioning the client on their side is the priority because it helps maintain airway safety and prevents aspiration during oral care. This step must be done first before beginning the cleaning process. B. Clean the client's mouth with foam swabs: Oral cleaning is important to reduce bacterial growth and maintain comfort, but it should only be performed after the client is positioned safely to avoid aspiration. C. Position an emesis basin under the client's chin: The emesis basin helps catch secretions and cleaning solution, but this is a supportive measure that comes after ensuring the client’s airway protection through proper positioning. D. Place a towel under the client's head: A towel provides comfort and helps keep linens dry, but it is a secondary measure. Airway protection through positioning always takes priority before comfort and cleanliness.
