How are IV medications typically delivered?

IV medications are typically delivered through IV push or a volume control administration set because these methods enable direct and immediate access to the bloodstream. This allows for rapid onset of action for medications, which is crucial for emergencies or when immediate therapeutic effects are needed.

The IV push method involves the direct administration of the medication into the intravenous line, allowing it to enter the circulation quickly, which is ideal for scenarios requiring fast relief or intervention. The volume control administration set, on the other hand, regulates the amount of fluid and medication being infused over a period, ensuring a consistent and controlled delivery, which is important for maintaining therapeutic drug levels without overwhelming the system.

In contrast, subcutaneous injection, oral administration, and intramuscular injection are inappropriate for IV medication delivery due to their slower absorption rates and potential delays in therapeutic effect. Each of these alternative routes is designed for different purposes and conditions, making them unsuitable for situations requiring the immediate efficacy provided by IV delivery.
