Final answer:
The correct practice in wound irrigation is allowing the cleaning solution to flow from less to more contaminated areas, using gentle pressure and methods to avoid further contamination or tissue damage.
Step-by-step explanation:
The correct action taken during wound irrigation is to allow the solution to flow from the least contaminated to the most contaminated area. This technique ensures that the irrigation solution does not spread contaminants to cleaner areas of the wound, which could increase the risk of infection. The use of appropriate pressure is important; too much pressure can damage tissues, while too little may not be effective at cleaning the wound. The syringe tip should not be inserted into the drainage site, as this can introduce bacteria. When cleansing the skin, it is crucial to use gentle friction as opposed to rigorous friction, which could further damage or irritate the wound.
