What type of medication can be delivered through an IV?

Intravenous (IV) therapy is a method used to deliver a variety of substances directly into a patient's bloodstream, making it a versatile option for treatment. The ability to administer both fluids and medications through an IV line is essential for a range of medical situations, including hydration, medication administration, and nutritional support.

Fluids, such as saline and dextrose solutions, are often used to maintain or restore hydration and electrolyte balance. Medications, including antibiotics, analgesics, and chemotherapy drugs, can also be delivered via IV to ensure rapid onset of action and higher bioavailability compared to oral administration. This dual capability is critical in emergency situations where time is of the essence, allowing for immediate therapeutic intervention.

The other choices are limited in their scope; they only mention fluids, electrolytes, or nutrients and exclude the wider range of medications that can also be delivered, thereby failing to capture the comprehensive utility of IV therapy in clinical practice. This makes the correct choice a more accurate reflection of the diverse applications of IV medication administration.
