During wound care, which practice prevents contamination?

• A. Clean technique
• B. Aseptic technique
• C. Handwashing is optional
• D. Handling with dirty gloves

Answer: (B)

Aseptic technique is used to prevent contamination during wound care by maintaining a sterile environment and using sterile supplies. This approach keeps microbes out of the wound by using sterile gloves, sterile dressings, and a sterile field, while everyone involved performs hand hygiene and avoids touching sterile areas with nonsterile items. Clean technique reduces microorganisms but doesn’t guarantee sterility, which is why it’s not sufficient for wound care requiring infection prevention. Handwashing is essential, and handling with dirty gloves would introduce pathogens, not prevent them. Using aseptic technique directly minimizes the risk of introducing contaminants and supports proper healing.
