Where is an IV generally started?

• A. Most peripheral site that is available and appropriate for the situation
• B. Carotid artery
• C. Jugular vein
• D. Central venous catheter site

Answer: (A)

An IV is generally started in a peripheral vein because it’s the quickest, least invasive, and safest way to get fluids and medications into the circulation. The typical choice is a vein in the hand, forearm, or antecubital area where a cannula can be placed easily with a tourniquet and kept secure, while avoiding sites that are infected, edematous, or near joints that could kink the catheter. Central venous access (such as via the jugular or other central veins) or arterial access (like the carotid) is reserved for situations where peripheral access fails or when long-term, highly specific monitoring or administration is needed, given the higher risks and invasiveness. In short, start with the most accessible peripheral site; move to central lines only if necessary.
