Catheters are placed in which of the following locations?

• A. Blood vessels
• B. Bladder
• C. Spine
• D. All of the above

Answer: (D)

Catheters are tubes inserted into body spaces to access fluids or spaces for administration or drainage. They can be placed in blood vessels to deliver medications or withdraw blood, in the bladder to drain urine or monitor urine output, and in the spinal canal to access cerebrospinal fluid or deliver medications directly to the CNS. Because catheterization is possible at multiple sites depending on the clinical need, “All of the above” is the best answer. This also highlights the importance of sterile technique, confirming correct placement, and ongoing care to prevent infections or other complications.
