What action helps prevent obstruction of a catheterized patient’s drainage, particularly with a suprapubic catheter?

• A. Regularly assess catheter patency and drainage.
• B. Leave the catheter clamped at all times.
• C. Flush with household solutions without order.
• D. Remove and replace the catheter daily.

Answer: (A)

Keeping the drainage pathway open hinges on regular checks of catheter patency and drainage. By routinely assessing how well the catheter is draining—observing the urine output, watching for backflow, and ensuring the tubing and collection bag aren’t kinked, kinked, or compressed—you can catch early signs of blockage and intervene before drainage stops. For a suprapubic catheter, ensure the tubing from the bladder to the bag lies smoothly with no sharp bends, secure the catheter to prevent movement that could kink the line, and keep the collection bag below the level of the bladder so gravity aids flow.

If drainage slows or stops, follow the protocol for obstruction rather than clamping or unprescribed interventions. Clamping can cause bladder distention, flushing with household solutions is unsafe, and daily removal/replacement is unnecessary and risky. Regular assessment and proper positioning of the drainage system help prevent obstruction and maintain continuous drainage.
