Chronic wounds that are not healing well may benefit from (Select all that apply.)

Choice A rationale:

Alginate dressings are highly absorbent and suitable for wounds with heavy drainage. They also promote hemostasis by activating the intrinsic pathway of the clotting cascade.

Choice B rationale:

Dry gauze is not the best choice for a bleeding wound as it does not have hemostatic properties.

Choice C rationale:

Hydrogel dressings are primarily for wounds with little to no exudate and not suitable for a bleeding wound.

Choice D rationale:

Transparent dressings are thin, waterproof dressings used for superficial wounds and not suitable for a bleeding wound.

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.
