Question

The normal levels of sodium in plasma is
1. 135-143 mEq/L
2. 97-106 mEq/L
3. 90-196 mg/100 ml
4. 60-100 mg/dl
5.

Answer 1

Correct Answer - Option 1 : 135-143 mEq/L

Explanation

• Measurement of sodium is a routine in assessing electrolyte, renal, and cardiac function.
• ​Hypernatremia also spelled hypernatraemia, which is a high concentration of sodium in the blood.
• This condition can be managed by sodium bicarbonate, hypertonic glucose, and insulin infusion.

Normal range and intake

• Average daily intake in adults ranges from 90-250 mmol/d.
• The reference range for serum sodium is 135-147 mmol/L.

​Applications

• Assessing water balance.
• Acid-base balance.
• Heart failure
• Renal failure
• Hepatic disease
