Q. The primary reason for the decreased medullary hypertonicity associated withosmotic diuresis is: (Solved)
1. an associated increased urine volume
2. the limiting concentration gradient for sodium reabsorption is reached
3. tubular fluid has an increased sodium concentration
4. the total amount of sodium reaching the loop of Henle is increased
5. the associated maximal vasopressin secretion
- b. the limiting concentration gradient for sodium reabsorption is reached
