Question 1

A patient with rosacea wants to know which common trigger they should avoid. Which of the following is a well-recognized rosacea trigger?

Accepted Answer

Spicy foods and alcohol

Answer

Spicy foods, alcohol, heat, and emotional stress are classic rosacea triggers that cause flushing and flare-ups.

Question 2

When teaching a patient with atopic dermatitis about the 'soak and seal' technique, what does 'seal' refer to?

Accepted Answer

Applying moisturizer or emollient immediately after bathing to trap moisture

Answer

The 'seal' step involves applying an emollient within 3 minutes of patting skin dry to lock in moisture and repair the skin barrier.

Question 3

A patient prescribed a high-potency topical corticosteroid asks why it should not be applied to the face. The best explanation is:

Accepted Answer

Facial skin is thinner and more absorbent, increasing the risk of atrophy and telangiectasia

Answer

The face has thin, highly permeable skin that absorbs more corticosteroid, making side effects like skin thinning and visible vessels more likely.

Question 4

Which of the following should be included when counseling a patient about proper sunscreen application?

Accepted Answer

Apply sunscreen 15–30 minutes before sun exposure and reapply every 2 hours

Answer

Sunscreen needs 15–30 minutes to bind to the skin and must be reapplied every 2 hours or after swimming/sweating.

Question 5

A patient undergoing laser hair removal asks how many sessions are typically needed. The dermatology tech should explain that multiple sessions are required because:

Accepted Answer

Laser only destroys hair follicles in the active (anagen) growth phase

Answer

Laser hair removal targets the pigment in actively growing (anagen) follicles, and since follicles cycle asynchronously, multiple sessions are needed.
