What is the first step in the process of starting an IV?

The first step in starting an IV is selecting an appropriate site. This involves assessing the patient's veins and choosing the most suitable location for catheter insertion, typically based on factors such as vein accessibility, size, and condition. Selecting the right site is critical because a well-chosen vein can reduce patient discomfort and improve the chances of successful catheter placement on the first attempt.

After determining the appropriate site, other steps follow, such as applying a tourniquet, cleaning the area, and then proceeding to insert the catheter. Each of these subsequent steps relies on first having a proper and strategic site selection in order to ensure a smooth and safe IV initiation process.
