When performing a shave biopsy, which instrument is most commonly used to obtain the specimen?
Answer: Flexible razor blade
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.
A patient undergoing a cryotherapy procedure for an actinic keratosis develops a blister at the treatment site 24 hours later. This response is considered:
Answer: An expected tissue response to liquid nitrogen
Blister formation after cryotherapy is an expected inflammatory response as the treated tissue undergoes freeze-thaw injury and subsequent healing.
Which topical anesthetic is most commonly applied prior to laser procedures in dermatology?
Answer: EMLA (lidocaine/prilocaine) cream
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.
During wound care for a post-procedural dermatology patient, which dressing type creates a moist wound environment to promote healing?
Answer: Hydrocolloid dressing
Hydrocolloid dressings maintain a moist wound environment, which accelerates re-epithelialization and reduces pain compared to dry dressings.
What is the correct angle for intralesional injection of a corticosteroid into a hypertrophic scar?
Answer: 10–15 degrees (nearly parallel)
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.
When educating a patient about post-procedure sun protection after a chemical peel, which SPF is the minimum recommended for daily use?
Answer: SPF 30
The American Academy of Dermatology recommends a minimum of SPF 30 for daily sun protection, particularly after resurfacing procedures that increase photosensitivity.
