What are the primary uses for an IV or PICC line?

The primary uses for an IV (intravenous) or PICC (peripherally inserted central catheter) line are to administer medications, nutrients, and hydration directly into the bloodstream. This method is particularly advantageous because it allows for immediate absorption and distribution throughout the body, which is critical in situations where rapid treatment is necessary.

Medications delivered through these lines can include a variety of intravenous drugs for pain management, antibiotics, or chemotherapy, which require precise and controlled administration. Additionally, for patients who cannot consume food orally, these lines enable healthcare providers to deliver essential nutrients and hydration directly, ensuring that the patient receives the necessary care and support for recovery or ongoing health maintenance.

The other choices do not align with the primary functions of IV or PICC lines, as they serve very different purposes in medical care. For instance, administering physical therapy is a procedural action that does not involve infusion lines, monitoring blood pressure typically involves non-invasive technologies rather than intravenous access, and performing surgery is a distinct process that may utilize these lines afterward but not as part of the surgical procedure itself.
