In case of drowning in sea water: TN 06
**Core Concept**
Drowning in sea water is a complex clinical scenario that requires understanding of the pathophysiological changes that occur due to the ingestion of seawater. The body's response to the high salt concentration in seawater can lead to severe hypernatremia and electrolyte imbalances.
**Why the Correct Answer is Right**
When a person ingests seawater, the high concentration of sodium chloride can lead to rapid absorption of sodium ions into the bloodstream. This results in severe hypernatremia, which can cause dehydration of brain cells and potentially lead to seizures, coma, and even death. The body's attempt to dilute the sodium levels can lead to hyponatremia, which can cause cerebral edema and further exacerbate the situation.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not take into account the specific pathophysiological changes that occur due to the ingestion of seawater.
**Option B:** This option is incorrect because it does not address the rapid absorption of sodium ions into the bloodstream, which is the primary cause of hypernatremia in this scenario.
**Option C:** This option is incorrect because it does not consider the potential for cerebral edema and seizures due to the severe hypernatremia.
**Clinical Pearl / High-Yield Fact**
In cases of drowning in sea water, it is essential to consider the potential for severe hypernatremia and electrolyte imbalances, which can have devastating consequences if not promptly recognized and treated.
**Correct Answer: C. Hypernatremia is the primary cause of death in drowning in sea water.**
