What common solution is used in medical treatments?

• A. Inhalants
• B. Powders
• C. Capsules
• D. 5 percent dextrose in water

Answer: (D)

Medical treatments often rely on liquids that can be given directly into the body, serving as hydration and as carriers for drugs. Among the options, the only actual liquid solution is five percent dextrose in water. This IV fluid is widely used because it provides sterile fluid and can act as a diluent or vehicle for medications, while the dextrose also offers a small caloric source during infusion. Inhalants are gases or aerosols for respiratory delivery, not liquids; powders and capsules are solid dosage forms, not solutions. A practical note: the dextrose is rapidly metabolized, so the solution becomes free water over time, which influences its use based on a patient’s electrolyte status.
