What is the correct initial action when inserting a peripheral intravenous catheter?

The correct initial action when inserting a peripheral intravenous catheter is to apply a tourniquet and palpate a vein for insertion. This step is crucial because it helps to engorge the veins, making them more prominent and easier to access. By using a tourniquet, blood is temporarily trapped in the veins, which allows the healthcare provider to identify a suitable vein for catheter placement.

Once a suitable vein has been located, the provider can then proceed with the next steps in the catheter insertion process, such as cleaning the skin and preparing the site, which are important for infection control. However, the process begins with ensuring that the right vein is chosen, as this sets the foundation for the rest of the procedure. Stabilizing the vein and skin preparation come after this initial step.

This method enhances the likelihood of a successful insertion on the first attempt, which is important for minimizing patient discomfort and preventing complications.
