Which practice supports aseptic technique in wound care?

• A. Touching wound with bare hands
• B. Reusing non-sterile dressings
• C. Applying sterile dressings
• D. Delaying dressing changes

Answer: (C)

Maintaining a sterile environment is essential in wound care to prevent infection. Applying sterile dressings provides a barrier free of microbes between the wound and the outside environment, helping to keep the wound clean as it heals. This is the practice that directly supports aseptic technique by ensuring the dressing itself doesn’t introduce contaminants. Touching a wound with bare hands, reusing non-sterile dressings, or delaying dressing changes all increase the risk of introducing or allowing growth of bacteria in the wound, which can lead to infection.
