Which of the following indicates that breathing may be inadequate?

The presence of no air being felt or heard at the nose or mouth is a strong indicator that breathing may be inadequate. Inadequate breathing can lead to critical situations where the body is not receiving enough oxygen, which can result in hypoxia and other serious complications. If air is not moving in or out of the respiratory passages, it signals that ventilation is not occurring effectively. This situation necessitates immediate evaluation and potential intervention to restore adequate breathing and oxygenation.

In contrast, clear and loud breath sounds typically suggest that air is moving freely through the airways, indicating adequate breathing. Feeling energized implies that the patient is likely receiving sufficient oxygen, which contradicts the idea of inadequate breathing. A normal breathing rate suggests that the respiratory function is stable and within normal limits, further indicating that breathing is adequate at the moment.
