Answer: B

Explanation:

Always work quickly once you have tightened the tourniquet: leaving it on for more than a minute may cause discomfort for the patient and even have damaging results. If you are unable to find a suitable vein and carry out the procedure within one minute, loosen the tourniquet, allow blood to flow again normally and then retry, or choose another site.
