Which of the following statements about medicated shampoos is false?

• A. They are not typically used to treat poison ivy or poison oak
• B. They can help with dandruff
• C. They can be prescribed for skin infections
• D. They may contain medicated ingredients like chlorhexidine

Answer: (A)

Medicated shampoos are used to address specific skin issues by delivering active ingredients such as antifungals, antibacterials, and anti-itch or anti-inflammatory agents. They can help manage dandruff, support treatment of skin infections, and may contain ingredients like chlorhexidine.

Saying they are not typically used to treat poison ivy or poison oak isn’t accurate. In cases where dermatitis from irritants like urushiol is present, a medicated shampoo can be part of the overall care plan to cleanse the coat, soothe the skin, and help prevent secondary infection or worsening inflammation. So this statement isn’t correct, even though those toxins aren’t treated directly by the shampoo itself. The other statements reflect common, appropriate uses of medicated shampoos: they can help with dandruff, they can be prescribed for skin infections, and they may contain medicated ingredients like chlorhexidine.
