The Nurse Has Applied a Disposable Heat Pack to a Client's

The nurse has applied a disposable heat pack to a client's back. After 15 minutes of treatment, the client says that the pack no longer is warm and asks the nurse to increase the temperature. How should the nurse evaluate this request?

A) Adaptation of the thermal receptors often results in the decreased sensation of warmth.
B) The heat pack should be replaced with a slightly increased temperature of a thermal application.
C) This client may be experiencing a rebound effect from the heat application.
D) Since this client's thermal tolerance is higher than normal, increasing the temperature is necessary.
