Question 1

When recommending an over-the-counter topical medication to treat a dermatologic condition, which instruction to the patient is important to enhance absorption of the drug?&#10;A) Apply a thick layer of medication over the affected area.&#10;B) A solution spray preparation will be more effective on hairy areas.&#10;C) Put cool compresses over the affected area after application.&#10;D) Use a lotion or cream instead of an ointment preparation.

Accepted Answer

Solution spray preparations are more effective on hairy areas because they can be applied more evenly and reach the skin surface more effectively than creams or ointments, which can get caught in the hair. This ensures better absorption of the medication into the skin.

Question 2

An adult patient has been diagnosed with atopic dermatitis and seborrheic dermatitis with lesions on the forehead and along the scalp line. Which is correct when prescribing a corticosteroid medication to treat this condition?

A) Initiate treatment with 0.1% triamcinolone acetonide.
B) Monitor the patient closely for systemic adverse effects during use.
C) Place an occlusive dressing over the medication after application.
D) Prescribe 0.05% fluocinonide to apply liberally.

A

Accepted Answer

Corticosteroids, like 0.1% triamcinolone acetonide, are commonly used to treat dermatitis. This concentration is appropriate for the face and scalp, where a mid-potency corticosteroid is often recommended due to the sensitivity of the skin in these areas.

Question 3

A provider is prescribing a topical dermatologic medication for a patient who has open lesions on a hairy area of the body. Which vehicle type will the provider choose when prescribing this medication?

A) Cream
B) Gel
C) Ointment
D) Powder

B

Accepted Answer

Gels are particularly suitable for hairy areas because they are less messy and easier to apply than creams or ointments, and they can penetrate the skin well without clogging hair follicles.
