Which lumen arrangement does a triple lumen catheter utilize?

• A. One lumen
• B. Two lumens
• C. Three distinct lumens
• D. Four lumens

Answer: (C)

A triple lumen catheter is designed with three distinct lumens, which allows for simultaneous access to the vascular system while administering multiple therapies. Each lumen can be used independently for different purposes, such as delivering medications, infusing fluids, or drawing blood. This arrangement provides flexibility in treatment, enabling healthcare providers to manage complex medical needs without the need to insert multiple catheters. This design is particularly beneficial in situations where patients require various intravenous therapies concurrently, as it maximizes the efficiency of access while minimizing patient discomfort related to catheter placement. Each lumen is typically dedicated to a specific function (for example, one lumen for high-volume fluid infusion, another for blood sampling, and the third for medication administration), which enhances patient safety and therapeutic effectiveness.
