The practical nurse (PN) is providing oral care for a client who is unconscious. Which action should the PN take?

A. Use normal saline to rinse the client's mouth: Normal saline is safe, non-irritating, and helps maintain oral mucosa integrity. B. Avoid contact with the roof of the mouth: Unnecessary; oral care includes cleaning all oral surfaces gently. C. Lower the head of the bed to 30 degrees: This increases aspiration risk; the head should be elevated or the client positioned side-lying. D. Don sterile gloves prior to performing oral care: Clean gloves are sufficient; sterile gloves are not required.
