When preparing an IV piggyback medication, which practice is essential to prevent contamination?

• A. Wear non-sterile gloves to check the IV site.
• B. Prepare the IVPB at the bedside without a sterile field.
• C. Place the IVPB at a lower level than the existing IV.
• D. Use sterile technique when preparing the medication.

Answer: (D)

Preventing contamination during IV piggyback preparation requires sterile technique. By performing hand hygiene, establishing and maintaining a sterile field, and using sterile gloves and equipment, you keep the medication and IV connections free of microbes as you prepare and administer it. This approach directly reduces the risk of introducing pathogens into the IV line, which is essential for patient safety. The other practices don’t provide the same level of asepsis: non-sterile gloves don’t protect a sterile field, preparing at the bedside without a sterile setup invites environmental contaminants, and simply placing the IV piggyback at a lower level doesn’t address aseptic technique.
