Which statement about tunneled catheters is true according to the material?

• A. Usually only used for a few weeks
• B. Usually used for long-term access
• C. Never used in ICU
• D. Only used for dialysis

Answer: (A)

Tunneled catheters are designed for long-term venous access. They’re placed under the skin with a subcutaneous tunnel and a cuff that helps tissue grow in and reduces infection, which supports ongoing use over extended periods. Because of this design, they’re intended for months of dwell time, not just a few weeks. They’re not limited to ICU and aren’t used only for dialysis; they’re used for a variety of therapies that require repeated venous access, such as chemotherapy, parenteral nutrition, or long-term antibiotics. So, the true statement is that they’re usually used for long-term access.
