National IV Nurse Day is observed every January 25 to honor nurses who assist patients undergoing infusion therapy. This day highlights the critical role of IV nurses, who manage intravenous treatments, ensuring the safety and comfort of patients. The United States House of Representatives supported the establishment of this observance in 1980, with backing from organizations like the Infusion Nurses Society. The holiday recognizes the dedication of IV nurses in making infusion therapy effective and as painless as possible. Typical customs include thanking IV nurses, sending greeting cards or small gifts, donating to charities that support nurses, and promoting the day on social media using the hashtag #NationalIVNurseDay.
