Integumentary System Exam Questions Questions
Question 1 of 5
From what layer of skin are melanosomes released?
Correct Answer: A
Rationale: The correct answer is A: stratum basale. Melanosomes, which contain melanin pigment responsible for skin color, are produced and released by melanocytes in the stratum basale layer of the epidermis. Melanocytes transfer melanosomes to neighboring keratinocytes, providing protection against UV radiation. The other choices are incorrect because melanosomes are not released from the reticular layer of dermis (B), stratum corneum (C), or hypodermis (D). The stratum corneum is the outermost layer of the epidermis composed of dead skin cells, while the hypodermis is primarily involved in fat storage and insulation.
Question 2 of 5
Physician who specializes in diagnosing and treating disorders of the skin
Correct Answer: A
Rationale: The correct answer is A: dermatologist. A dermatologist is a physician who specializes in diagnosing and treating disorders of the skin. They undergo specific training in dermatology, making them experts in skin conditions. Sweat glands (B) are not physicians but structures in the skin. Keratosis (C) refers to a skin condition characterized by rough, scaly patches. Dysplastic Nevi (D) are atypical moles that may require monitoring by a dermatologist but do not specialize in treating skin disorders.
Question 3 of 5
You perform a skin assessment on a new resident in an LTC facility. Which of the following is of most concern?
Correct Answer: D
Rationale: The correct answer is D because an irregular border on a mole can be indicative of melanoma, a type of skin cancer. It is crucial to identify and address any concerning skin lesions promptly to prevent potential complications. A: Numerous striae are common and not typically a cause for immediate concern. B: Thickened and yellow toenails may indicate a fungal infection but are not as concerning as a potential melanoma. C: Silver-colored scaling on elbows and knees may suggest conditions like psoriasis, which are important to address but not as urgent as a suspicious mole.
Question 4 of 5
A client admitted to the ED complains of itching of the trunk and groin. You note the presence of multiple reddened wheals on the chest, back, and groin. Which question is most appropriate to ask next?
Correct Answer: D
Rationale: The most appropriate question to ask next is D: Are you taking any new medications? This is because the symptoms described, itching and reddened wheals, are suggestive of an allergic reaction, which can be caused by medications. By asking about new medications, you can identify potential triggers for the symptoms. Choice A (family history of eczema) is less relevant as the focus should be on the current symptoms and potential triggers. Choice B (sunscreen use) is not as pertinent to the symptoms described. Choice C (stress management) is important for overall health but is not directly related to the current presentation of symptoms.
Question 5 of 5
Which of the following actions helps the nurse assess the skin temperature?
Correct Answer: D
Rationale: The correct answer is D because placing the dorsum of the hand on the surface of the skin allows the nurse to assess the skin temperature accurately. The dorsum of the hand is a more sensitive area for detecting subtle temperature changes compared to the palm. By using the dorsum of the hand, the nurse can feel the skin temperature without altering it. Inspection and palpation (Choice A) may provide information about skin color and texture but not specifically about skin temperature. Detecting moisture with the palmar surface (Choice B) is more related to assessing skin moisture rather than temperature. Grasping the skin (Choice C) may help assess skin turgor but not temperature.
