What temperature range is a crushed ice pack typically applied at?

The correct choice specifies that a crushed ice pack is typically applied at a temperature range of 30°F to 32°F. When using ice for therapeutic purposes, the goal is to effectively reduce swelling and numb the area to alleviate pain without causing tissue damage. The temperature range of 30°F to 32°F is ideal because it is just above freezing, allowing the ice pack to maintain a cold enough temperature to provide the desired therapeutic effects, while minimizing the risk of frostbite or other cold-induced injuries to the skin and underlying tissues.

In contrast, other temperature ranges mentioned in the options would either be too cold or not cold enough for effective cryotherapy. For example, temperatures closer to 0°F or below can lead to tissue damage more rapidly due to extreme cold exposure. Meanwhile, temperatures like 5°F to 10°F or 15°F to 20°F may not achieve the necessary degree of cold needed to effectively manage inflammation or pain in an athletic training context. Therefore, the 30°F to 32°F range is considered safe and effective for therapeutic use in athletic training environments.
