Final answer:
If a dressing bleeds through, apply another dressing on top without removing the original one and maintain pressure. Continue adding layers if needed and seek medical attention if bleeding persists.
Step-by-step explanation:
When a dressing bleeds through, you should not remove the original dressing. Instead, you must apply additional pressure to the area and place another dressing on top of the original. If bleeding continues and seeps through the additional dressing, continue to apply more layers without removing the previous ones, ensuring to maintain pressure each time. It is important to monitor the bleeding and if it does not stop or if you cannot control it, it is crucial to seek medical attention immediately as it may be a sign of a more serious injury or condition.
