Define the term "flush" in relation to IV therapy.

• A. Administering a medication
• B. Instilling a small amount of solution to keep the catheter patent
• C. Draining the IV line
• D. Changing the IV dressing

Answer: (B)

The term "flush" in relation to IV therapy refers specifically to instilling a small amount of solution—commonly saline or a compatible fluid—through an intravenous catheter. This practice is essential for several reasons. Mainly, it helps maintain patency of the catheter by clearing any potential blockages that could arise from blood or medication deposits within the line. Additionally, flushing ensures that the medication administered via the IV is fully delivered into the bloodstream and minimizes the risk of complications such as phlebitis or infection. The other options do not accurately represent the concept of flushing. Administering a medication involves delivering therapeutics rather than ensuring the catheter remains clear. Draining the IV line suggests removing fluid, which does not align with the purpose of flushing. Changing the IV dressing pertains to maintaining the site’s integrity and cleanliness, which, while important, is a different aspect of IV care. Thus, the definition provided accurately captures the role and importance of flushing in intravenous therapy.
