A nurse is assisting with the development of a teaching plan for a client who has psoriasis. Which of the following statements should the nurse include in the plan?

A. Hot water can irritate psoriatic plaques and worsen inflammation. Patients are advised to use lukewarm water when bathing to avoid exacerbating symptoms. B. Moisturizing the skin is important, but warm moist compresses are not typically used in psoriasis management. They may temporarily relieve discomfort but do not treat the underlying hyperproliferation of skin cells. C. Coal tar preparations are a standard treatment for psoriasis. Coal tar slows skin cell growth, reduces scaling, itching, and inflammation, and can be used in combination with other topical or systemic therapies. Including this in the teaching plan helps the client understand what to expect from treatment. D. While some psoriasis lesions may cause mild discomfort or itching, pain management is not the primary focus of treatment. The main goal is to control excessive skin cell proliferation, inflammation, and scaling.
