A typical rehydration solution for dehydration contains which components?

• A. Protein, Fat, and Vitamins
• B. Glucose, Sodium, and Potassium
• C. Calcium, Magnesium, and Phosphate
• D. Chloride, Bicarbonate, and Nitrate

Answer: (B)

Rehydration solutions are crafted to restore fluid plus the key electrolytes lost during dehydration, and they work best when they also promote rapid water absorption in the gut. The crucial element is glucose because it enables sodium—and therefore water—to be pulled into the bloodstream through the sodium-glucose co-transport mechanism in the small intestine. That makes the combination of glucose with sodium particularly effective for quick rehydration. Potassium is included to replace losses and maintain cellular and cardiac function. Together, glucose, sodium, and potassium address both fluid deficit and electrolyte balance, which is why this set is the best fit for a typical rehydration solution. Other components don’t meet the primary goal as directly. Protein, fat, and vitamins are nutrients, not the electrolytes needed for immediate rehydration. Calcium, magnesium, and phosphate are important minerals in other contexts but aren’t the standard mix for acute rehydration. Chloride and bicarbonate appear in some solutions, but nitrate is not a typical component, and the core rehydration benefit comes from glucose with sodium and potassium.
