A nurse is teaching the parents of a child with frequent nosebleeds how to care for the child. Which statement by the parents indicates that they have understood the teaching?

The correct answer is B because sitting the child upright and forward and applying pressure to the sides of the nose helps to control the nosebleed by applying pressure to the bleeding vessels. This position helps prevent blood from flowing back into the throat and reduces the risk of swallowing blood. Turning the head to the side (choice A) may lead to blood flowing down the throat. Having the child lie flat and applying pressure to the cheeks (choice C) is not effective in controlling nosebleeds. Putting the child in bed, elevating the head slightly, and pressing on the forehead (choice D) can increase blood flow to the head and is not recommended.
