B) Applying a keratolytic agent like salicylic acid
C) Taking a pair of tweezers and pulling the wart off
D) How to safely use cryotherapy at home
Ans: B
Feedback:
Verrucae, or warts, are common, benign papillomas caused by DNA-containing human papillomavirus (HPV) that invade the superficial skin keratinocytes. Removal is usually done by applying a keratolytic agent, such as salicylic acid, which works by dissolving intercellular cement and producing desquamation of the horny layer of skin without affecting normal epidermal cells. Steroid creams will not help with removal of a wart. Pulling the wart off is not recommended. Cryotherapy may be needed, but this is performed in a doctor's office.
