Question 1 of 5

What are some of the common skin diseases?

Correct Answer: D

Rationale: The correct answer is D because all the other choices mention specific skin diseases that fall under the broader category of common skin diseases. Eczema, psoriasis, acne (A), melanoma, basal cell carcinoma, squamous cell carcinoma (B), and warts, herpes, shingles (C) are all prevalent skin conditions that affect many individuals. By selecting choice D, you encompass all the mentioned skin diseases, providing a comprehensive overview of common skin conditions.

Question 2 of 5

A client has peripheral arterial disease (PAD). What statement by the client indicates misunderstanding about self-management activities?

Correct Answer: A

Rationale: The correct answer is A because using a heating pad can worsen PAD by dilating blood vessels, leading to reduced blood flow. Step 1: Heating pad increases blood flow, potentially worsening PAD symptoms. Step 2: Choices B, C, and D promote proper self-management by avoiding leg crossing, wearing warm socks for circulation, and quitting smoking to improve blood flow.

Question 3 of 5

Melanoblasts lie-

Correct Answer: C

Rationale: The correct answer is C: In stratum malpighi. Melanoblasts are responsible for producing melanin, the pigment that gives skin its color. They are located in the stratum malpighi layer of the epidermis, where they transfer melanin to nearby keratinocytes. Choice A is incorrect because the stratum corneum is the outermost layer of the epidermis composed of dead cells. Choice B is incorrect as the dermis is a layer of skin beneath the epidermis. Choice D is incorrect because melanoblasts are located in the stratum malpighi, not at the junction of epidermis and dermis.

Question 4 of 5

Melanocytes or melanophores are placed at places in between-

Correct Answer: A

Rationale: The correct answer is A because melanocytes are located in the basal layer of the epidermis (stratum germinativum), where they produce melanin. Melanin then transfers to neighboring keratinocytes to protect the skin from UV radiation. Choices B, C, and D are incorrect because melanocytes are not found in the stratum lucidum, subcutaneous layer, or stratum granulosum. The stratum lucidum is a translucent layer without melanocytes, the subcutaneous layer contains adipose tissue but not melanocytes, and the stratum granulosum is the layer above the stratum germinativum where keratinocytes undergo changes in morphology.

Question 5 of 5

The transparent layer is formed from

Correct Answer: D

Rationale: The correct answer is D, Stratum lucidum of skin. This layer is a thin, transparent layer found in the epidermis of the skin, specifically in hairless areas of the body. It is composed of dead skin cells that are flattened and densely packed. The transparency of this layer is due to the lack of organelles and nuclei in the cells, allowing light to pass through easily. The other choices (A: Stratum spongiosum, B: Epidermis, C: Stratum compactum) do not accurately represent the transparent layer formed in the skin. The epidermis as a whole contains multiple layers, with the stratum lucidum being the specific layer responsible for transparency.
