The diagnostic criteria for acne vulgaris may include the identification of which of the following?

Explanation: Regular monitoring of liver function is essential for clients receiving oral antibiotics for acne vulgaris because some antibiotics may have the potential to cause hepatotoxicity (liver damage). Monitoring liver function helps detect any adverse effects and ensures the client's safety during treatment.

Incorrect choices: a. Encourage the client to avoid consuming dairy products during antibiotic treatment. - There is no specific evidence that links dairy consumption with the effectiveness of oral antibiotics for acne vulgaris. Dairy restriction is not typically indicated for clients on acne treatment.

b. Educate the client on the importance of sun exposure for vitamin D synthesis. - While sun exposure can contribute to vitamin D synthesis, it is not specifically relevant to the client's treatment with oral antibiotics for acne vulgaris. In fact, sun exposure should be minimized or accompanied by sunscreen due to the potential for photosensitivity caused by some antibiotics.

d. Recommend the use of topical benzoyl peroxide in combination with oral antibiotics. - This may be a valid treatment option; however, the question specifically asks for a nursing management action related to the oral antibiotics. The nurse's responsibility is to monitor the client's response to the prescribed oral antibiotics and potential side effects, not topical treatment recommendations.

Explanation: Oral retinoids, such as isotretinoin, are beneficial for severe acne vulgaris and can effectively reduce sebum production, skin inflammation, and acne lesions.

Incorrect choices: a. Oral antihistamine - Oral antihistamines are not typically used to treat acne vulgaris. They are used to manage allergy symptoms but do not target the underlying causes of acne.

b. Oral corticosteroid - Oral corticosteroids may be used in some cases of severe inflammation, but they are not a primary treatment for acne vulgaris and have potential side effects with long-term use.

d. Oral antibiotic - Oral antibiotics are used to treat acne when there is bacterial involvement, but they may not be as effective as oral retinoids in severe cases and may contribute to antibiotic resistance over time.
