Which of the following is the correct order of layers encountered during a punch biopsy from superficial to deep?
Answer: Epidermis → Dermis → Subcutaneous fat
The correct anatomical order from superficial to deep is epidermis, dermis, then subcutaneous fat (hypodermis), which guides biopsy depth planning.
A patient has a documented allergy to amide local anesthetics. Which alternative should the CDT report to the provider before preparing for a procedure?
Answer: Benzocaine (ester-type)
Benzocaine is an ester-type local anesthetic and is structurally distinct from amide anesthetics (lidocaine, mepivacaine, bupivacaine), making it a potential alternative for patients with amide allergies.
Proper labeling of a skin biopsy specimen container requires all of the following EXCEPT:
Answer: Pathologist's name
The pathologist's name is not required on the specimen container; required labels include patient name, date, and biopsy site to ensure proper identification and chain of custody.
When assisting with Mohs micrographic surgery, the CDT's role in tissue processing includes:
Answer: Mapping and color-coding tissue specimens per Mohs protocol
The CDT assists with mapping and color-coding Mohs tissue stages according to protocol, while diagnosis and margin interpretation are performed by the Mohs surgeon.
What is the primary reason for using a chalazion clamp during eyelid procedures in dermatology?
Answer: To provide hemostasis and stabilize the lesion during removal
A chalazion clamp provides hemostasis by compressing blood vessels and stabilizes the eyelid lesion, facilitating safe removal of the cyst.
Which antiseptic solution is contraindicated for use near the eyes and ears during pre-procedural skin prep?
Answer: Chlorhexidine gluconate
Chlorhexidine gluconate is ototoxic and can cause corneal damage; it is contraindicated for prepping near the eyes and ears, where povidone-iodine is preferred.
A patient presents with severe contact dermatitis on both arms after a patch test. The CDT should first:
Answer: Document the reaction and notify the supervising dermatologist immediately
A severe reaction must be documented and reported to the supervising dermatologist immediately so that appropriate medical management can be initiated.
