Though starting an IV isn't nearly as serious of an undertaking as more complicated procedures, it still requires the same basic level of preparation and precaution as any minor medical procedure. Before you begin, you'll want to have all of the tools and equipment you need handy and you'll want to be sure that any materials which will come into contact with the patient's body — especially your needles — are fresh and sterile. To start a typical IV line, you will need:  Sterile disposable gloves Appropriate size "over-the-needle" IV catheter (typically 14 - 25 gauge) Bag of IV fluid Non-latex tourniquet Sterile bandage or dressing Gauze Alcohol wipes Medical tape Sharps container Sterile pad or paper (set small tools out on this to keep them close at hand) An important part of the process of starting an IV is introducing yourself to the patient and explaining the procedure that's about to occur. Talking to patients and sharing this basic information helps put them at ease and ensures that no part of the process surprises or shocks them. In addition, it ensures that you have their full consent to proceed. When you're done, have the patient lay or recline where they'll be receiving their IV.  When patients are nervous, their veins may contract somewhat in a process called vasoconstriction. This makes it harder to start an IV, so make sure your patient is as relaxed and comfortable as possible before proceeding. You may want to ask whether the patient has had any trouble with IVs in the past. If so, the patient may be able to tell you which sites are easiest to access. Next, prime the IV tubing by suspending the IV bag from an elevated stand, filling the tubing with saline solution, and checking for any bubbles. If necessary, clamp the tubing so that the solution doesn't drip onto the floor. Be sure to remove any bubbles from the tubing by gently tapping, squeezing, or flushing them out of the line. A dated and signed sticker should then be placed on both the IV tubing and the IV bag.  Injecting air bubbles into...
