What is a common use of a central line?

A central line is commonly used for medication delivery due to its ability to provide direct access to the central venous system. This access allows for the administration of a variety of medications, including those that may be irritating to peripheral veins or require rapid delivery. Central lines are especially beneficial for patients who need long-term intravenous therapy or for those with difficult venous access.

Furthermore, they allow for high-volume infusions and hypertonic solutions which might not be feasible through peripheral veins. Additionally, central lines can be used to draw blood samples, providing a convenient way to obtain venous blood without the need for multiple venipunctures. This makes them a versatile tool in medical settings where ongoing treatment and monitoring are necessary.

Other options may involve different aspects of patient care but do not encompass the full range of effective uses central lines provide, particularly in terms of medication administration.
