Answer: Maintaining safety
Explanation: When it comes to deficit / hyperactivity disorder (ADHD), in addition to impaired attention and hyperactivity, impulsive behaviour is also present, which can occur suddenly. It can cause excessive and impaired motor activity that can result, as in this case, in head-banging or hair pulling as well as other dangerous activities that can lead to injury. Possible self-harming injuries are a priority that should be taken care of during the care of such a child. Apart from, of course, other elements of care such as regular sleep, nutrition, but maintaining safety in this case is primary care.
