What is the recommended dressing change frequency for a transparent central line dressing?

• A. Every 3 days
• B. Only when changed by physician
• C. Every 7 days, or sooner if damp, soiled, or loose
• D. Every 14 days

Answer: (C)

Transparent central line dressings are kept in place as long as they remain clean, dry, and intact, so you can visually monitor the insertion site. The recommended practice is to change the dressing every 7 days if it’s dry and intact, and sooner if it becomes damp, soiled, or loose. This schedule balances minimizing manipulation with maintaining a strong barrier against infection. If the dressing is damp or loose, bacteria can gain access and travel along the catheter track, so an immediate change helps preserve safety. Longer intervals or waiting for a physician to order a change aren’t appropriate because they increase infection risk and delay necessary care.
