NCCPA Dermatology CAQ Examination Practice Test
The NCCPA Dermatology CAQ Examination practice page covers clinical assessment and management of skin, hair, and nail disorders. Its question bank includes lesion evaluation, inflammatory and infectious skin conditions, pigmentary concerns, and periocular presentations, with emphasis on interpreting examination findings and choosing an appropriate next step.
Exam overview
About the NCCPA Dermatology CAQ Examination Exam
Dermatology care requires distinguishing benign patterns from lesions that warrant biopsy or other diagnostic evaluation, using features such as asymmetry, border irregularity, color variation, and change over time. Cases also test recognition of urgent infection and inflammation, including painful erosions in a patient with atopic dermatitis and eyelid swelling with impaired vision or painful eye movement. Management decisions may involve initial treatment for cellulitis or erysipelas, counseling on recurrent herpes labialis, and supportive care for keratosis pilaris or melasma. Nail findings can require separating chronic paronychia from other causes of nail dystrophy. Build a consistent approach: identify key morphology and distribution, assess systemic symptoms and red flags, select a diagnostic or treatment action, and account for the risks of delay or inappropriate therapy.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A 68-year-old has a broad, irregular, velvety brown patch on the upper back. The lesion has gradually enlarged and is not uniformly colored. Which diagnostic method is most appropriate to evaluate it?
Show answer
Correct answer: AA changing, irregularly pigmented lesion warrants tissue diagnosis to assess for melanoma or another neoplasm. Biopsy selection depends on the lesion and clinical circumstances, but histopathologic examination is needed for diagnosis.
A patient with atopic dermatitis has widespread erythema, fever, and numerous monomorphic, painful, punched-out erosions that began rapidly. What is the most appropriate management?
Show answer
Correct answer: AEczema herpeticum is disseminated herpes simplex infection in eczematous skin. Rapid onset of painful, monomorphic erosions with systemic symptoms warrants urgent assessment and prompt systemic antiviral treatment.
A patient develops a tender, red, swollen area around the eye with fever. The eyelid is markedly edematous, and the patient reports pain when moving the eye and blurred vision. What is the most appropriate action?
Show answer
Correct answer: APain with eye movement and impaired vision are concerning for orbital involvement rather than uncomplicated preseptal infection or dermatitis. Orbital cellulitis is a vision- and life-threatening emergency requiring urgent evaluation, imaging as indicated, and systemic treatment.
A 54-year-old with longstanding diabetes has thickened, brittle fingernails and a proximal nail fold that is chronically swollen and tender. Which organism is commonly associated with chronic paronychia?
Show answer
Correct answer: AChronic paronychia is commonly associated with repeated moisture and irritant exposure, which disrupt the nail-fold barrier; Candida may be present. Management focuses on keeping the area dry and reducing irritant exposure, with topical anti-inflammatory treatment often used. It differs from acute bacterial paronychia, which develops rapidly and may form an abscess.
A 10-year-old develops several small, smooth, skin-colored papules on the backs of both hands. The lesions have a flat top and are asymptomatic. Which diagnosis is most likely?
Show answer
Correct answer: AVerruca plana (flat warts) typically presents as multiple smooth, flat-topped papules, often on the face or dorsal hands. Common warts are usually rough and hyperkeratotic; molluscum papules are typically dome-shaped with central umbilication.
A 48-year-old has a slowly enlarging, asymmetric pigmented lesion on the calf with irregular borders and several shades of brown and black. What is the most appropriate diagnostic step?
Show answer
Correct answer: BA changing lesion with asymmetry, irregular borders, and color variation is concerning for melanoma. Excisional biopsy with narrow margins is generally preferred to establish diagnosis and assess Breslow thickness; destructive treatment can impair diagnosis and staging.
A patient with a longstanding history of facial hyperpigmented patches asks how to reduce worsening discoloration. Which daily measure is most useful?
Show answer
Correct answer: AUltraviolet exposure can worsen melasma and other forms of facial hyperpigmentation. Broad-spectrum sunscreen, sun-protective clothing, and limiting exposure are important foundational measures.
How to use this practice test
The free US Practice Tests bank contains 50 published questions. Each practice session presents up to 20 questions selected at random and displays results after completion. Use the cases to check how reliably you identify lesion patterns, recognize urgent presentations, and choose diagnostic or initial management steps; review missed items against your clinical reasoning.
Preparation tips
- For pigmented lesions, practice documenting asymmetry, border, color variation, evolution, and the findings that support biopsy or specialist evaluation.
- Compare urgent periocular infection features—especially fever, painful eye movement, and visual change—and identify when immediate escalation is needed.
- Review morphology and distribution for common disorders represented in cases, including flat warts, keratosis pilaris, melasma, and recurrent herpes labialis.
- For inflammatory or infectious eruptions, connect presentation and systemic symptoms to the appropriate initial management, including painful punched-out erosions in atopic dermatitis.
- Distinguish chronic paronychia findings from nail plate changes, and review the role of Candida in chronic nail-fold inflammation.
