Which of the following statements regarding drowning is correct?

• A. A. Patients with a submersion injury might deteriorate rapidly because of pulmonary injury and cerebral hypoxia.
• B. B. Large amounts of water enter the lungs in a small number of drowning victims.
• C. C. Artificial ventilations can easily be performed in patients with a laryngospasm.
• D. D. Hypoxia in the drowning victim initially occurs due to water in the lungs.

Answer: (A)

The statement about patients with a submersion injury potentially deteriorating rapidly due to pulmonary injury and cerebral hypoxia accurately reflects the critical physiological processes at play during drowning incidents. When a person is submerged, the immediate concern is the entry of water into the lungs, which can severely impair gas exchange, leading to pulmonary injury. This impairment can result in hypoxia, where the body's tissues, especially the brain, are deprived of adequate oxygen. Cerebral hypoxia is particularly concerning because the brain is highly sensitive to oxygen deprivation, and significant, prolonged hypoxia can cause irreversible damage. The combination of pulmonary injury from water inhalation and subsequent hypoxia can lead to rapid deterioration in victim condition, making timely and effective medical intervention crucial. In contrast, the incorrect statements either reflect misunderstandings of the drowning physiology or highlight situations that are not standard in drowning scenarios. For example, the assertion about large amounts of water entering the lungs in a small number of victims does not align with typical drowning cases, as many victims may not inhale substantial amounts of water. Moreover, the difficulty of performing artificial ventilations due to laryngospasm suggests that while airway obstruction can occur, it is not a common factor in all drowning cases. Lastly, hypoxia in drowning
