The sodium content of ileostomy output can be as high as 120 mEq/L. What value does this represent?

• A. 180 mEq/L
• B. 120 mEq/L
• C. 60 mEq/L
• D. 240 mEq/L

Answer: (B)

Sodium content in ileostomy output is reported as milliequivalents per liter, and for sodium the milliequivalents per liter equal millimoles per liter (since Na+ has a valence of +1). If the output can be as high as 120 mEq/L, that is the concentration value: 120 mEq/L, which is the same as 120 mmol/L. This reflects a substantial sodium load in the ileostomy fluid, important for guiding electrolyte replacement. The other numerical choices would indicate different concentrations and do not match the stated value.
