Which of the following is an example of an IV solution?

The choice of dextrose/normal saline (D5NS) as an example of an IV solution is correct because it is a commonly used intravenous fluid that combines dextrose (a simple sugar) and normal saline (a solution of sodium chloride in water) to provide hydration, electrolytes, and calories for patients. This specific formulation can be administered directly into the bloodstream for various medical conditions, making it a typical example of an IV solution.

Dextrose/normal saline is particularly beneficial in clinical settings where maintaining glucose levels and fluid balance is crucial, such as in patients undergoing surgery or those with certain metabolic conditions. Its use helps prevent complications related to dehydration and electrolyte imbalance, which can occur when individuals are unable to consume food or fluids orally.

Other options, while they may have relevance in pharmacy and patient care, are not classified as standard IV solutions. Benzyl alcohol, for example, is typically used as a preservative and not administered as a standalone intravenous solution. Water for injection is a sterile water source but is often used as a diluent rather than a direct IV solution. Sodium bicarbonate is a compound used to treat specific medical conditions, but it is also not typically administered as a standalone IV fluid in the same manner as D
