3. The nurse explains how prolonged application of ice can lead to tissue damage from prolonged vasoconstriction; therefore, the nurse includes instructions to apply the ice for 20 minutes, remove the ice for 30 minutes, and to check affected tissue before repeating the cycle to prevent tissue damage.
1. Applying ice for 5-minute increments is subtherapeutic treatment.
2. The nurse avoids teaching the client to leave the ice in place until the ice melts be-cause it is likely to result in ice application exceeding 20 minutes and increase the risk for tissue damage.
4. Application of ice for 1 hour exceeds the 20-minute recommendation to prevent tissue damage.
