Moist heat has the physiological effect of:
Numbing the area treated.
Dilating the blood vessels.
Drawing fluid to the site of application.
Constricting the blood vessels.
The Correct Answer is B
Choice A rationale:
Numbing the area treated is not a physiological effect of moist heat. Moist heat primarily works by increasing blood flow to the treated area.
Choice B rationale:
Dilating the blood vessels is the correct answer. Moist heat therapy works by increasing the temperature of the skin/soft tissue, which leads to vasodilation and increased blood flow to the treated area.
Choice C rationale:
Drawing fluid to the site of application is not a physiological effect of moist heat. Moist heat primarily works by increasing blood flow to the treated area.
Choice D rationale:
Constricting the blood vessels is not a physiological effect of moist heat. Moist heat primarily works by increasing blood flow to the treated area through vasodilation.
