When replenishing fluids with a glucose solution, what percentage of glucose and electrolytes is most useful?

6%.

Explanation:

Intravenous glucose solution contains a mixture of glucose especially dextrose and water is used for medicinal purpose. The water loss that occur during fever or any disease can be treated by the glucose solution.

Different glucose level that can be used for the treatment is 5% to 6%, 105 and 0.45 %. The administration of 5 to 6 % sugar solution maintains the balance between hyper glycemia and hypoglycemia. These reactions are activated by sympathetic division that maintains the electrolyte balance in the body.

Thus, the answer is 6%.
