Before using a syringe to collect blood, the plunger should be pulled back to break the seal and expel any air present in the syringe. This ensures proper collection of blood without any air entering the needle or vein. Option B is incorrect as loosening the hub of the needle could cause the needle to detach or leak during collection. Option C is incorrect as the use of anticoagulant is not necessary for all blood collections and should only be used in certain situations based on the type of test being performed. Option D is incorrect as vacuum tube adapters are not needed when using a syringe for blood collection.
