Serum sodium is 124 mmol/L and glucose is 600 mg/dL. Using the correction of 1.6 mmol/L of sodium for each 100 mg/dL of glucose above 100, what is the corrected sodium?
Answer and explanation
Correct answer: D. 132 mmol/L
- Step 1: The excess glucose is 600 - 100 = 500 mg/dL.
- Step 2: Correction = 1.6 x 5 = 8, so corrected sodium = 132 mmol/L.
Answer
132 mmol/L.
