The sodium content of ReSoMal (rehydration solution for malnourished children) is –
**Core Concept**
ReSoMal is a specialized rehydration solution designed for malnourished children, aiming to correct dehydration and electrolyte imbalances while taking into account their specific nutritional needs. It contains a unique blend of electrolytes and glucose to promote optimal rehydration.
**Why the Correct Answer is Right**
The sodium content in ReSoMal is crucial to prevent overcorrection of hyponatremia, which can lead to seizures and other complications. The solution contains a relatively low concentration of sodium (2.6 mmol/L or 75 mEq/L) to avoid rapid shifts in serum sodium levels. This is in contrast to standard ORS (Oral Rehydration Solution), which has a higher sodium concentration (75 mEq/L). The carefully balanced electrolyte composition in ReSoMal helps to restore fluid and electrolyte balance in malnourished children without causing further harm.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately reflect the sodium content of ReSoMal. The exact sodium concentration of ReSoMal is 2.6 mmol/L.
* **Option B:** This option is incorrect because it is too high, which could lead to overcorrection of hyponatremia and potential complications in malnourished children.
* **Option C:** This option is incorrect because it is too low, which may not provide sufficient sodium replacement and could exacerbate hyponatremia.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that ReSoMal has a distinct electrolyte composition compared to standard ORS, making it a critical choice for rehydrating malnourished children. Always consult the WHO guidelines for the most up-to-date recommendations on rehydration solutions.
**Correct Answer:** C. 75 mEq/L
