Final answer:
It is not recommended to apply an aquathermia pad over hot compresses due to the risk of excessive heat which can lead to burns or other injuries. Only one heat source should be used at a time based on the treatment protocol.
Step-by-step explanation:
When using hot compresses, it is generally not recommended to apply an aquathermia pad over the compress. The hot compress itself is intended to provide sufficient heat to the area being treated, and the use of additional heat sources such as an aquathermia pad may result in excessive heat, potentially leading to burns or other injuries. Instead, either the hot compress or the aquathermia pad should be used individually, based on the recommended treatment protocol for the specific medical condition.
