A client visits the clinic and is diagnosed with seborrheic dermatitis. The health care provider prescribes treatment. Which should the nurse anticipate giving to the client for treatment?

Seborrheic dermatitis is a chronic, relapsing inflammatory skin condition affecting sebaceous gland-rich areas such as the scalp, face, and chest. It involves an overgrowth of Malassezia yeast and a dysregulated inflammatory response, leading to erythematous, scaly, greasy plaques. Desonide is a low-potency topical corticosteroid commonly prescribed for seborrheic dermatitis to reduce inflammation and relieve pruritus; it is a standard and appropriate first-line treatment, particularly for facial involvement where more potent steroids could cause skin atrophy. Cephalexin is a first-generation cephalosporin antibiotic used for bacterial infections such as cellulitis or impetigo; seborrheic dermatitis is not a bacterial infection, so this medication is not indicated. Escitalopram is a selective serotonin reuptake inhibitor antidepressant used for depression and anxiety disorders, which has no role in treating a skin condition. Meperidine is an opioid analgesic used for pain management; seborrheic dermatitis, while uncomfortable, does not warrant opioid treatment. Desonide's anti-inflammatory properties directly address the pathophysiology of seborrheic dermatitis, making it the most appropriate anticipated treatment from the options provided.
