When a nurse initiates IV therapy, which initial action is most critical?

The initial action of identifying the patient is critical when initiating IV therapy because it ensures patient safety and helps prevent potential errors such as medication administration to the wrong individual. Confirming the patient's identity through methods such as using their name and date of birth prior to any intervention is essential in safeguarding against miscommunication and ensuring that the right treatment is provided to the right person. This step aligns with the principles of patient safety and is a fundamental part of nursing practice.

While preparing the IV site, gathering supplies, and beginning the infusion are also important steps in the process, they follow after confirming the correct patient identity. Without proper identification, the subsequent actions could lead to serious medical errors, making it the most critical initial action in the initiation of IV therapy.
