According to WHO, what is the sodium concentration in the reduced-osmolarity oral rehydration solution recommended for children with acute diarrhea?

  • A 90 mmol/L
  • B 75 mmol/L
  • C 60 mmol/L
  • D 45 mmol/L
Correct answer: B. 75 mmol/L

Explanation

WHO recommends reduced-osmolarity ORS with sodium 75 mmol/L, glucose 75 mmol/L, and total osmolality 245 mOsm/L. This replaced the original 90 mmol/L formulation as it reduces stool output, vomiting, and need for IV therapy. The reduced osmolarity is safe for both non-cholera and cholera diarrhea in children. The full composition includes potassium 20 mmol/L and citrate 10 mmol/L.
