What is the maximum time length a tourniquet can be left on?

30 seconds
45 seconds
60 seconds
75 seconds

The correct answer is: 60 seconds

The maximum time length a tourniquet can be left on during venipuncture is typically around 1 minute, or 60 seconds. Keeping a tourniquet on for longer than this can lead to hemoconcentration, which can affect laboratory test results and potentially cause discomfort or damage to the vein. Leaving it on for the recommended time allows for the necessary engorgement of the veins, making the puncture easier while minimizing the risk of complications. Therefore, 60 seconds aligns with best practices in phlebotomy, ensuring both patient safety and the accuracy of test results.
