Choice A rationale:

Using small ice cubes is not necessary when applying an ice pack. The size of the ice does not affect the therapeutic effect of the cold therapy.

It is not necessary to fill the pack and refreeze it. The ice pack should be used as is and can be refrozen after use if needed.

Choice C rationale:

Using a light cover on the pack is necessary to prevent direct contact of the ice with the skin, which can cause cold injury or frostbite.

Covering the pack with plastic wrap is not necessary. The ice pack usually comes in a waterproof bag that prevents water leakage.

Serosanguineous drainage is a mixture of blood and serous fluid, often seen in new wounds. This matches the description given in the question.
