Which action assesses patency of prehospital IV lines?

• A. Assess patency of prehospital IV lines
• B. Flush with saline without assessment
• C. Remove and reinsert
• D. Check only the IV site appearance

Answer: (A)

Patency means the IV line is open and able to deliver fluids or medications without blockage, kinks, or infiltration. In the prehospital setting, you verify patency by actively confirming flow, typically by checking for blood return and performing a gentle saline flush while observing for smooth, unobstructed flow and no resistance. This direct assessment ensures the line can actually function before administering any fluids or drugs. The best action is to assess patency itself because it explicitly checks that the line is functioning. Flushing with saline without assessment can hide problems like a blocked or kinked line. Removing and reinserting is unnecessary unless there’s clear evidence of a failed line. Checking only the appearance of the IV site can miss issues with flow, so it’s not sufficient on its own.
