Normal saline is an example of what type of solution?

Normal saline is classified as an intravenous (IV) solution primarily because it is commonly used in clinical settings for intravenous therapy. This sterile solution consists of sodium chloride (NaCl) in water, and it is isotonic, meaning it has the same osmotic pressure as bodily fluids. Its main applications include rehydration, electrolyte balance, and as a vehicle for administering medications directly into the bloodstream.

Intravenous solutions are specifically formulated to be compatible with the human body; they must meet stringent sterility and composition standards to ensure patient safety when delivered via the IV route. Normal saline serves as a significant component in various IV therapies and is widely utilized in hospitals for fluid replacement and maintenance.

Oral and topical solutions serve different delivery methods and are not intended for the IV route, while suspensions refer to a different formulation type where solid particles are dispersed in a liquid but may not fully dissolve.
