Which of the following diagnostic criteria is NOT commonly used to identify acne vulgaris?

A.

Family history of acne

B.

Skin biopsy

C.

Presence of rash on the hands and feet

D.

Physical examination of the skin

Answer and Explanation

The Correct Answer is C

Explanation: The presence of a rash on the hands and feet is not a common diagnostic criterion for acne vulgaris. Acne vulgaris primarily affects the face, neck, chest, and back, and rashes on the hands and feet are not characteristic of this condition.

Incorrect choices: a. Family history of acne - A family history of acne is a relevant diagnostic criterion as there can be a genetic predisposition to developing acne.

b. Skin biopsy - A skin biopsy may be used in some cases to confirm the diagnosis of acne vulgaris and rule out other skin conditions with similar presentations.

d. Physical examination of the skin - Physical examination of the skin is a standard diagnostic approach for identifying acne vulgaris. It involves assessing the presence of comedones, papules, pustules, nodules, and cysts on the skin.

Correct Answer is B

Explanation

Explanation: Choice b indicates a need for further teaching because scrubbing the face vigorously can irritate the skin and worsen acne lesions. Gentle cleansing is recommended to avoid skin irritation and inflammation.

Incorrect choices: a. "I will cleanse my face with a gentle, non-abrasive cleanser twice daily." - This statement is correct as gentle cleansing with a non-abrasive cleanser can help remove excess oil, dirt, and debris from the skin without causing irritation.

c. "I will avoid using oil-based moisturizers on my face." - This statement is correct as oil-based moisturizers can clog pores and worsen acne. Non-comedogenic, oil-free moisturizers are recommended for acne-prone skin.

d. "I will avoid picking or squeezing my acne lesions." - This statement is correct as picking or squeezing acne lesions can lead to infection, inflammation, and scarring. It is important to leave acne lesions untouched and let them heal naturally.

Correct Answer is A

Explanation

Explanation: Choice a indicates a need for further teaching because washing the face several times a day can strip the skin of its natural oils and lead to dryness and irritation. Over-washing can also worsen acne by disrupting the skin's natural barrier and increasing oil production.

Incorrect choices: b. "I will use oil-free and non-comedogenic makeup products." - This statement is correct as using oil-free and non-comedogenic makeup products can help prevent clogged pores and further acne breakouts.

c. "I will avoid picking or squeezing my acne lesions to prevent scarring." - This statement is correct as picking or squeezing acne lesions can lead to infection, inflammation, and scarring.

d. "I will apply a thick layer of petroleum jelly to moisturize my skin." - This statement is incorrect because petroleum jelly is not recommended for acne-prone skin. Non-comedogenic, oil-free moisturizers are preferred for individuals with acne vulgaris.
