Rock, Paper, Scissors

You are about to perform a radial arterial line for continuous hemodynamic monitoring as well as multiple ABGs when your senior resident says: "Wait, did you perform the test?"

Challenge: Few people do it, but it's the proper thing to do. What test?

The Allen’s test is shown. The Allen’s (or modified Allen’s) test is a measure of collateral circulation and should be done prior to radial or dorsalis pedis puncture. The patient’s hand is held high with the fist clenched and both the radial and ulnar arteries compressed. The hand is then lowered, the fist is opened, and pressure is released from the ulnar artery. If color returns within 6 seconds, the ulnar artery and superficial palmar arch are patent.
