Question 1 of 5
All of the following are true of epidermal ridges except that they
Correct Answer: A
Rationale: The correct answer is A because epidermal ridges do not extend into the dermis. The ridges are formed by the epidermis and serve to increase friction for grasping objects. Choice B is correct as epidermal ridge patterns are genetically determined. Choice C is also correct as the ridges interconnect with dermal papillae for stability. Choice D is incorrect as epidermal ridges do contain increased numbers of free nerve endings, contributing to the sense of touch.
Question 2 of 5
An albino individual lacks the ability to produce
Correct Answer: B
Rationale: The correct answer is B: melanin. Melanin is the pigment responsible for determining the color of the skin, hair, and eyes. Albino individuals lack melanin production, leading to their characteristic lack of pigmentation. Perspiration (A), carotene (C), and hemoglobin (D) are not affected by albinism. Perspiration is produced by sweat glands, carotene is a pigment found in fruits and vegetables, and hemoglobin is a protein in red blood cells responsible for carrying oxygen.
Question 3 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 4 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 5 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.
