Step-by-step explanation:
If a hemorrhage occurs during a venipuncture, immediate action must be taken to control the bleeding. The first step is to apply direct pressure to the site of the hemorrhage using sterile gauze or a clean cloth. If the bleeding does not stop, a tourniquet can be used to temporarily cut off blood flow to the limb. It is important to seek medical attention as soon as possible to evaluate the extent of the hemorrhage and provide appropriate treatment.
