Which of the following is a symptom of near drowning?

Pulmonary edema is indeed a symptom associated with near drowning, primarily because it involves the accumulation of fluid in the lungs. When a person nearly drowns, inhaling water can lead to inflammation and fluid buildup in lung tissues, resulting in pulmonary edema. This condition can impair gas exchange and lead to serious respiratory distress. It's important for divers and rescue personnel to recognize this symptom, as it necessitates immediate medical intervention to prevent the deterioration of the victim's respiratory status.

In contrast, the other options—fever, skin rash, and chest pain—may not directly correlate with the immediate aftermath of near drowning. While chest pain can potentially arise due to various causes, it is not a definitive symptom of near drowning like pulmonary edema. Fever and skin rash are generally more indicative of infections or allergic reactions, rather than a direct result of the drowning event itself. Thus, understanding pulmonary edema as a key indicator helps divers and rescuers respond effectively in emergencies.
