Explanation

A. Applying an ice pack may provide temporary relief from discomfort by numbing the area, but the primary purpose of using ice after applying a topical agent is to slow the absorption of the drug.

C. Ice packs are not typically used to enhance drug excretion. They primarily affect absorption rather than excretion.
