Certified Nursing Assistant (CNA) Prometric Practice Exam

In which situation would you most likely perform oral care for an unconscious patient?

1. When they are medically stable

2. Before administering medications

3. Every 2 hours, to keep the mouth clean

4. When the patient expresses discomfort

The correct answer is: Every 2 hours, to keep the mouth clean

Performing oral care for an unconscious patient every 2 hours is essential for maintaining oral hygiene and preventing complications such as infections and aspiration. Unconscious patients are unable to perform oral hygiene themselves, which increases the risk of bacteria building up in the mouth. Regular oral care helps to remove accumulated plaque, food particles, and secretions, thus reducing the potential for oral infections and minimizing the risk of respiratory complications that can arise if oral secretions are aspirated into the lungs. Keeping the mouth clean is particularly crucial for unconscious patients because they often require support to maintain their overall health. Maintaining oral hygiene can also enhance comfort, promote dignity, and decrease the likelihood of more serious health issues related to poor oral hygiene management. This practice aligns with infection control measures and the standard of care in nursing protocols. Other considerations, like the patient's medical stability, medication administration, and expression of discomfort, may influence the timing of oral care but do not necessarily establish the routine and preventative approach typically taken with unconscious patients. The emphasis on scheduled oral care helps ensure their needs are consistently met.
