Question 1

When performing a shave biopsy, which instrument is most commonly used to obtain the specimen?

Accepted Answer

Flexible razor blade

Answer

A flexible razor blade (such as a DermaBlade) is the standard instrument for shave biopsies, allowing the dermis technician to feather the blade for a smooth, tangential cut.

Question 2

A patient undergoing a cryotherapy procedure for an actinic keratosis develops a blister at the treatment site 24 hours later. This response is considered:

Accepted Answer

An expected tissue response to liquid nitrogen

Answer

Blister formation after cryotherapy is an expected inflammatory response as the treated tissue undergoes freeze-thaw injury and subsequent healing.

Question 3

Which topical anesthetic is most commonly applied prior to laser procedures in dermatology?

Accepted Answer

EMLA (lidocaine/prilocaine) cream

Answer

EMLA cream, a eutectic mixture of lidocaine and prilocaine, is the most widely used topical anesthetic for pre-laser analgesia due to its effectiveness and safety profile.

Question 4

During wound care for a post-procedural dermatology patient, which dressing type creates a moist wound environment to promote healing?

Accepted Answer

Hydrocolloid dressing

Answer

Hydrocolloid dressings maintain a moist wound environment, which accelerates re-epithelialization and reduces pain compared to dry dressings.

Question 5

What is the correct angle for intralesional injection of a corticosteroid into a hypertrophic scar?

Accepted Answer

10–15 degrees (nearly parallel)

Answer

Intralesional injections into hypertrophic scars or keloids are performed at a nearly parallel (10–15 degree) angle to deliver medication directly within the dermis of the scar.
