Which of the following is NOT a type of IV fluid?

Distilled water is not classified as a type of IV fluid used in clinical settings. While it is generally pure and free from impurities, it lacks the necessary electrolytes and nutrients needed for intravenous therapy. IV fluids are typically designed to provide hydration, electrolyte balance, and nutrient therapy to patients and are prepared with specific solutions such as sodium chloride, lactated Ringer's solution, and glucose solutions.

Sodium chloride solutions contain sodium and chloride ions and are commonly used for fluid replacement and to maintain osmotic balance. Lactated Ringer's is an isotonic fluid that includes various electrolytes, mimicking the body's plasma composition, making it useful in various medical scenarios. Glucose 5% is also frequently used for providing calories and hydration while maintaining blood sugar levels.

In contrast, distilled water, while it may seem like a simple fluid, does not fulfill the requirements for IV therapy and can actually be harmful if administered directly, potentially leading to hemolysis or other complications due to its hypotonic nature. Therefore, it stands out as not being a suitable option among the common types of IV fluids.
