Explain the retrostasis action of the cold compress on the client's forehead when performing a hot foot bath

Question

What will be an ideal response?

Answer 1

The hot water in the foot tub produces a derivative effect, drawing blood and lymph from one part of the body to another, increasing circulation and relieving the congestion caused by a headache, sinus infection, sore throat, chest cold, or flu. The addition of a cold compress applied to the head enhances the derivative effect by causing vasoconstriction of those blood vessels, thus pushing blood down toward the feet.
