A nurse is performing wound care for a client who has an abdominal incision. Which of the following techniques should the nurse implement?

A. Cleanse the insertion site of the drain using a circular motion toward the center: When cleaning a drain site, the proper technique is to cleanse in a circular motion from the center outward to prevent introducing microorganisms into the wound. Cleaning toward the center increases the risk of contamination. B. Cleanse the wound starting at the bottom and moving upward: Wounds should be cleansed from the cleanest area to the least clean area, typically from top to bottom or from the incision outward, to reduce the risk of infection. Starting at the bottom can drag contaminants into the incision. C. Irrigate the wound with a low-pressure flow of solution: Low-pressure irrigation is recommended to effectively remove debris and exudate without damaging granulation tissue. High-pressure irrigation can traumatize the wound bed and impede healing. D. Irrigate the wound using a 10-mL syringe: A 10-mL syringe may produce high-pressure flow, which can harm delicate tissue. Wound irrigation should be performed using a method that provides gentle, controlled flow, often with larger-volume syringes or devices designed for low-pressure irrigation.
