Explain why the first step in responding to any sports injury is to remove the danger that led to the injury.
When someone sustains an injury while participating in sports, that indicates that something unexpected has occurred. There is a risk that the conditions that lead to the initial injury could continue to pose a health hazard both to the player who sustained the initial injury as well as other players; it is essential to remove that danger. Removing the danger could require stopping the sports activity or even transporting the injured person off the field of play. While it can be dangerous to move someone who has sustained an injury, it is more important to ensure the safety of the athlete by eliminating dangers that can result in severe injuries.
Explain what types of sports injuries for which it is appropriate to use over-the-counter medications and why.
Over-the-counter medications are generally best used for minor injuries where the pain and damage suffered are minimal. These medications generally have fewer side-effects than stronger medications, so their effectiveness for more serious injuries is limited. But the lower incidence of side effects also means that these drugs are generally safer to use.
Explain what distinguishes acute and chronic sports injuries.
Acute sports injuries are generally those that result from some sort of traumatic event on the body. Since they generally result from trauma, acute injuries tend to have a rapid onset and progression, but this can also mean that they will be of more limited duration. Chronic sports injuries, however, are generally those that develop over extended periods of time from overuse and improper exercise techniques. The slow onset and progression of chronic injuries tends to also extend the time needed to recover from them.
Explain how immobilizing an injured limb with a cast can enhance healing.
Immobilizing an injured limb enhances healing by preventing movements that can aggravate the injury and make it worse. This is the same reason why athletes should not continue to play a sport after suffering an injury: trying to push your body too far, too fast after suffering an injury can make it worse and prevent it from healing properly.
