What test must be preformed prior to an arterial line placement? Correct Ans= Allen's test
How often should a fast flush test be preformed? Correct Ans= Every 8 hours

Blood in the catheter system
Blood clot at the catheter tip
Kinking of the tubing system
Catheter tip lodging against the arterial wall
Soft, compliant tubing
Long tubing
Too many stopckcks (>3)
