Which ED procedure provides access to the central venous system for medications or fluids?

• A. Lumbar Puncture
• B. Conscious Sedation
• C. Central Line
• D. Femoral Stick

Answer: (C)

Access to the central venous system for medications or fluids is achieved with a central line. A central line is a catheter placed into a large central vein—typically the subclavian, internal jugular, or femoral vein—that enters the central circulation. This provides reliable, rapid administration of medications and large volumes, and is especially useful when peripheral IVs are difficult to place or when drugs (like vasopressors) require central administration or continuous central monitoring.

Lumbar puncture involves entering the spinal canal to collect cerebrospinal fluid or measure pressure, not establishing vascular access. Conscious sedation is a method of sedating a patient during a procedure and does not create venous access. A femoral stick refers to obtaining access in the femoral region, which is peripheral venous access and does not reach the central venous system. Therefore, the central line best fits the need for central venous access.
