Question 1

A patient with newly diagnosed psoriasis asks why their skin cells are turning over so rapidly. Which explanation is most accurate?

Accepted Answer

The immune system triggers abnormal signals that accelerate keratinocyte proliferation

Answer

Psoriasis is an immune-mediated condition in which inflammatory signals cause keratinocytes to proliferate far faster than normal.

Question 2

When counseling a patient about using a topical retinoid for the first time, which side effect should you specifically warn them to expect in the first 2–4 weeks?

Accepted Answer

Retinoid dermatitis (dryness, peeling, redness)

Answer

Retinoid dermatitis — dryness, peeling, and redness — is a common and expected initial reaction that typically subsides with continued use.

Question 3

A patient on isotretinoin asks if they can get a wax hair removal treatment. The correct response is:

Accepted Answer

Waxing should be avoided due to increased skin fragility and risk of skin lifting

Answer

Isotretinoin causes skin fragility and slows healing, making waxing likely to remove layers of skin and cause wounds.

Question 4

Which statement best describes the appropriate sun protection counseling for a patient using hydroquinone for hyperpigmentation?

Accepted Answer

Daily broad-spectrum SPF 30+ sunscreen is essential to prevent re-darkening

Answer

UV exposure stimulates melanocytes and will counteract hydroquinone's lightening effect, making daily sunscreen non-negotiable.

Question 5

A parent asks how to recognize signs of an allergic contact dermatitis reaction versus an irritant contact dermatitis reaction in their child. Which characteristic is more typical of allergic contact dermatitis?

Accepted Answer

Delayed onset (24–72 hours) after exposure to the allergen

Answer

Allergic contact dermatitis is a Type IV delayed hypersensitivity reaction that typically appears 24–72 hours after allergen exposure.
