Step-by-step explanation:
The statement that is false regarding mouth care of an unconscious patient is: 1) The patient's head should be turned to the side to prevent aspiration. This statement is actually true. When providing mouth care to an unconscious patient, it is important to turn their head to the side to prevent the risk of aspiration, which is the inhalation of oral secretions or foreign material into the airway.
The other statements are true. The patient's mouth should be cleaned with a soft toothbrush or sponge to maintain oral hygiene. Oral care should be performed every 2 hours to prevent bacterial growth and maintain oral health. Additionally, the patient's lips should be kept moist with a water-based lubricant to prevent dryness and discomfort.
