You are attending to a responsive teenager injured after falling off the diving board stairs. What should you do for the injured leg?

Manually stabilizing the injured leg is critical in providing immediate care for the teenager's injury. This action helps to prevent further injury or pain by restricting movement in the affected area. By stabilizing the leg, you maintain alignment and reduce the risk of aggravating the injury, whether it is a sprain, strain, fracture, or another type of trauma.

In the context of an injury, movement can lead to complications, such as worsening the damage or causing additional pain. Stabilization allows for better assessment of the severity of the injury and provides the injured individual with some comfort as further assistance or medical care is arranged.

Other approaches, such as applying ice, might also be beneficial later on, but they should typically follow stabilization and are not the immediate priority. Assisting the teenager to walk can lead to further injury, and calling their parents for assistance does not directly address the need for immediate stabilization and care. Thus, focusing on manual stabilization is the most appropriate and effective response in this situation.
