A nurse is assisting in the care of a client who is prescribed wound irrigation after abdominal surgery. Which of the following should the nurse identify as proper technique?

A. Fill a 20 mL syringe with irrigation solution: Small syringes, like 20 mL, generate excessive pressure that can damage healing tissue. A 30–60 mL syringe is typically recommended to provide safe, gentle irrigation without traumatizing the wound. B. Hold the syringe 7.5 cm (3 in) above the wound: Proper irrigation technique requires holding the syringe close enough to allow controlled flow but not so high as to increase pressure. Typically, the syringe tip is held just above the wound, about 1–2 inches, to avoid tissue injury. C. Allow solution to flow from the least to the most contaminated area: Directing irrigation from clean to contaminated areas prevents introduction of pathogens into healthy tissue and reduces infection risk. This is a key principle of aseptic wound care. D. Use fast and continuous pressure when flushing the wound: High-pressure or rapid irrigation can damage granulation tissue and delay healing. Gentle, controlled pressure ensures debris is removed without harming the wound bed.
