Venipuncture
1. Drug is placed directly into a vein.
2. Needle length and gauge depend on the viscosity of the drug, the site selected, and the specific method of injection.
3. While injecting, observe site for extravasation or infiltration.
4. If extravasation occurs, the first step is to remove the needle, apply pressure to the injection site, and apply cold packs to relieve the discomfort.
