to make sure blood comes into the syringe, to be sure you're in the vein and not just stuck into the body. many injections are intravenous, meaning they work best when put INTO the blood. some are subcutaneous (below skin, not in muscle) or intramuscular (into the muscle). Neither of those two require you to be in the vein, pull back is unnecessary (especially if you inject further from larger veins, say in the butt, or biceps muscle.

How do you read the amount of medicine in a syringe in a syringe?
The same way you read ANY syringe. From www.wikipedia.com (http://en.wikipedia.org/wiki/Syringes), if you click on the image of the 10ml syringe, you'll see the markings on the barrel. You measure the units of fluid from the needle side back to the plunger - so as you pull back the plunger you draw in "x" ml's of fluid as marked from the needle back. Standard safety procedures surrounding the use of a syringe should always be followed, and in no way is this short answer a full and complete explanation of how to correctly/safely use a syringe.
