Which statement about a cold compression unit is true?

• A. It is less effective than ice alone
• B. It is more effective than just ice and is applied for 15 minutes every 2 hours
• C. It is only suitable for knee injuries
• D. It requires continuous monitoring for 8 hours

Answer: (B)

Cold therapy with compression works best when cooling is paired with external pressure, because the combination not only lowers tissue temperature but also helps move fluid out of the injured area. This makes swelling and pain control more effective than using ice alone, since the compression adds edema reduction and improves contact with the treated area. The statement reflects common clinical practice: apply the unit for about 15 minutes and repeat roughly every 2 hours in the acute phase. Short, repeated sessions maximize inflammation control while reducing the risk of skin injury or frostbite, and they fit well with daily activity and monitoring. A device isn’t limited to knee injuries; it’s used for various joints and soft tissue injuries. It doesn’t require continuous monitoring for eight hours; rather, you check skin integrity and comfort after each cycle and adjust as needed. Ice alone can’t provide the same level of edema control, and the other options misstate the typical scope of use and monitoring requirements.
