"Test, puff, squirt, show-me" is best described as what?

• A. Physician verbiage for technologists to inject into arteries or catheter
• B. A method of flushing contrast
• C. A protocol for checking catheter patency
• D. A technique for injecting saline to cleanse the arterial lumen

Answer: (A)

This phrase tests understanding of how physicians in the cath lab communicate with technologists. “Test, puff, squirt, show-me” is a casual, directive way for a doctor to tell staff to perform an injection into a catheter or artery and then verify the result on imaging. It isn’t describing a formal procedure for flushing contrast, checking patency with a protocol, or cleansing the lumen with saline. It’s about the physician’s instruction to inject and then confirm placement or flow by visualization, which is why the description aligns with physician-verbiage used by technologists in real procedures.
