What is a primary use for a UVC?

A primary use for a UVC, or umbilical venous catheter, is indeed the emergency administration of fluids and drugs. UVCs are commonly used in neonatology to provide access to the circulatory system of newborns, particularly those who may be critically ill or requiring intensive care. The catheter is inserted into the umbilical vein, allowing for rapid delivery of medications, blood products, and intravenous fluids, which are essential for managing acute medical conditions.

The other options involve procedures or support that do not align with the primary functions of a UVC. Routine blood pressure monitoring does not require a UVC, as it can be done using standard blood pressure cuffs. Assistance in breathing exercises is typically managed through respiratory therapy or ventilators, not through intravenous access. Long-term nutrition support is usually provided via other methods, such as a peripherally inserted central catheter (PICC) or a central venous catheter, rather than a UVC, which is intended for shorter-term use.
