What is the most essential practice to perform before IV cannulation to ensure asepsis?

• A. Washing hands with antibacterial soap and using chlorhexidine at the site
• B. Shaving the skin around the site
• C. Applying skin protectant solutions
• D. Using a cold antiseptic

Answer: (A)

Before inserting an IV cannula, the most essential step is thorough hand hygiene and applying an effective skin antiseptic at the insertion site. Washing with antibacterial soap reduces the microbes on your hands, while applying chlorhexidine to the skin decreases the microbial load at the entry point, together dramatically lowering infection risk. Chlorhexidine, especially when used with alcohol, provides rapid and lasting antimicrobial action, which is why it’s the preferred choice for skin prep around IV sites. Let the antiseptic dry completely to maintain its effectiveness. Shaving the area isn’t necessary and can cause tiny skin injuries that raise infection risk. Other measures like skin protectants or less effective antiseptics don’t substitute for proper hand hygiene and site antisepsis. This combination directly helps prevent catheter-related infections.
