Normal saline, or 0.9% sodium chloride solution, contains 154 milliequivalents of sodium per liter and notably, zero potassium. This simple electrolyte composition is a key feature that distinguishes it from more complex intravenous fluids like Lactated Ringer's solution.

A standard liter of D5 solution, which is a 5% dextrose solution, contains exactly 50 grams of glucose. This common intravenous fluid is used to provide fluid replenishment and minimal carbohydrate calories in a clinical setting.
