The nurse is preparing to obtain an arterial blood gas specimen from a client and plans to perform the Allen's test on the client. The nurse would perform the steps in which order to conduct an Allen's test? Arrange the actions in the order that they should be performed. All options must be used.
The Allen's test is performed before an arterial blood specimen is obtained from the radial artery to determine the presence of collateral circulation and the adequacy of the ulnar artery. Failure to determine the presence of adequate collateral circulation could result in severe ischemic injury to the hand if damage to the radial artery occurs with arterial puncture. The nurse would first explain the procedure to the client. To perform the test, the nurse applies direct pressure over the client's ulnar and radial arteries simultaneously. While applying pressure, the nurse asks the client to open and close the hand repeatedly; the hand should blanch. The nurse then releases pressure from the ulnar artery while continuing to compress the radial artery and then assesses the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, the ulnar artery is insufficient, indicating that the radial artery should not be used for obtaining a blood specimen. Finally, the nurse documents the findings.
