Final answer:
Topical enzymes are appropriately used for treating chronic dermal ulcers option (A). They break down dead tissue and aid in healing but are not typically used for conditions like psoriasis, minor sunburns, or fungal infections such as athlete's foot.
Step-by-step explanation:
After conducting an in-service program for nurses on the topic of topical drugs used to treat skin disorders, the teaching would be considered successful if the group identifies chronic dermal ulcers option (A) as an appropriate use for topical enzymes. Topical enzymes are used in the treatment of various skin conditions, and their role in assisting the debridement and healing of chronic dermal ulcers is well-established. They help by breaking down dead tissue and promoting the natural healing process. While they’re beneficial for conditions such as chronic ulcers, they are typically not used for widespread inflammatory conditions like psoriasis, minor burns such as first degree sunburn, or fungal infections like tinea pedis.
