Which statement about tunneled catheters is supported by the material?

• A. They are never used in ICU
• B. They are always the first choice for dialysis
• C. They are mainly used for long-term access
• D. They are sometimes used for ICU temperature monitoring or dialysis

Answer: (D)

Tunneled catheters are designed for long-term venous access and are placed with a subcutaneous tunnel to lower infection risk. In critical care, they can serve as dialysis access when a fistula isn’t available or ready, and there are configurations used for intravascular monitoring, including core temperature measurements. Because of this versatility, the material supports that they are sometimes used for ICU temperature monitoring or dialysis. The other statements don’t fit real-world practice: they aren’t never used in ICU, they aren’t always the first choice for dialysis (fistulas or grafts are preferred when possible), and while they provide long-term access, the highlighted ICU use is the most directly supported point.
