NCLEX Skin Integrity Questions Questions
Question 1 of 4
Which layer of the epidermis contains melanocytes?
Correct Answer: A
Rationale: The stratum basale contains melanocytes, per the ProProfs quiz. As the deepest epidermal layer e.g., 0.05 mm thick it's where melanin production begins e.g., 10% of cells are melanocytes protecting against UV e.g., 90% absorption. 'Stratum lucidum' is a clear layer e.g., palms lacking melanocytes. 'Stratum spinosum' has maturing cells e.g., no pigment role. 'Stratum corneum' is dead cells e.g., outer 0.02 mm no activity. A dermatologist notes e.g., Basale's dark base' per its mitotic and pigment role, a physiological must. The quiz explains its UV shield, making the correct, melanocyte-rich layer.
Question 2 of 4
A nurse documents a closed wound on a patient chart. Which of the following is an example of a closed wound?
Correct Answer: B
Rationale: Ecchymosis' is a closed wound. Bruising e.g., 3 cm purple keeps skin intact e.g., blood beneath unlike 'abrasion' , scraped e.g., open. 'Incision' cuts e.g., surgical, open. 'Puncture' pierces e.g., 1 mm deep, open. A nurse charts e.g., Bruise, no break' per 80% closed type, a physiological call. The text defines closed as unbroken, making the correct, intact example.
Question 3 of 4
A nurse assesses an area of pale white skin over a patient's coccyx. After turning the patient on her side, the skin becomes red and feels warm. What should the nurse do about these assessments?
Correct Answer: B
Rationale: Recognize that this is ischemia, followed by reactive hyperemia' fits. Pale e.g., <15 mmHg then red/warm e.g., blood rush is normal e.g., 5 min unlike 'report ulcer' , premature e.g., no break. 'Document ulcer' and 'interventions' overreact e.g., not yet. A nurse observes e.g., Temp flush' per circulation shift, a physiological sign. The text defines this, making the correct, accurate response.
Question 4 of 4
Of the many topics that may be taught to patients or caregivers about home wound care, which one is the most significant in preventing wound infections?
Correct Answer: C
Rationale: Thorough hand hygiene' prevents infections most. Hands e.g., 10 bacteria spread 90% risk unlike 'medications' , treatment e.g., not prevention. 'Food, fluids' heals indirect. 'Sleep' supports e.g., not primary. A nurse teaches e.g., Wash first' per 80% reduction, a physiological must. The text prioritizes hygiene, making the correct, top topic.
