Maximum permissible chloride level is
**Core Concept**
The question is testing the knowledge of chloride levels in the context of electrolyte balance, particularly in relation to the permissible limits for different electrolytes in the human body. Chloride is an essential electrolyte that plays a crucial role in maintaining fluid balance, pH, and nerve function.
**Why the Correct Answer is Right**
The maximum permissible chloride level is crucial in preventing hyperchloremic metabolic acidosis. The normal chloride level in the blood is around 96-106 mmol/L. However, in certain situations like renal failure or excessive chloride administration, chloride levels can rise, leading to hyperchloremic metabolic acidosis. The permissible limit for chloride is not well-defined, but it is generally considered to be around 110-120 mmol/L.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option does not provide a clear value, making it an ambiguous choice.
* **Option B:** This value is too high and may indicate the onset of hyperchloremic metabolic acidosis.
* **Option C:** This value is too low and may not be sufficient to maintain proper fluid balance and nerve function.
**Clinical Pearl / High-Yield Fact**
Chloride levels should be monitored closely in patients with renal failure or those receiving high chloride-containing fluids to prevent hyperchloremic metabolic acidosis.
**Correct Answer:** C. 110
