A nurse is assessing a client with peripheral artery disease (PAD). The client states walking five blocks is possible without pain. What question asked next by the nurse will give the best information?

Correct Answer: A

Rationale: The correct answer is A: "Could you walk further than that a few months ago?" This question helps assess the client's progression or regression of symptoms over time, providing valuable information on the course of the disease. It is crucial in understanding the client's functional status and disease progression. Choice B is incorrect as it focuses on the surface types the client walks on, which is less relevant compared to monitoring changes in walking distance. Choice C is irrelevant as it shifts the focus to an alternative exercise without addressing the current problem. Choice D is incorrect as it does not directly relate to the client's walking capacity and disease progression.

Correct Answer: A

Rationale: The correct answer is A: Stratum malpighi. Pigmented cells, known as melanocytes, are found in the stratum malpighi layer of the epidermis. Melanocytes produce melanin, a pigment that gives skin its color and protects against UV radiation. The other choices (B: Stratum granulosum, C: Stratum lucidum, D: Stratum corneum) do not contain pigmented cells. Stratum granulosum is where keratinization occurs, stratum lucidum is a translucent layer found only in thick skin, and stratum corneum is the outermost layer composed of dead keratinocytes.

Correct Answer: A

Rationale: The correct answer is A: Dermis of palms. The dermis of the palms is highly developed in laborers due to constant friction and pressure from manual labor. This layer thickens to provide protection and support. The subdermal layer is not typically highly developed in response to labor, and the epidermal layer may thicken but is not the primary layer affected. Choice D is incorrect because not all layers of the skin are equally affected by manual labor.

Correct Answer: B

Rationale: The correct answer is B: Skin is not slimy. Mucous glands produce a slimy substance called mucus, which serves to lubricate and protect various surfaces in the body. Skin in mammals is not supposed to be slimy, as it needs to maintain a dry and protective barrier. A: Skin does respire through diffusion, but this does not relate to the presence of mucous glands. C: Skin does have blood vessels for nourishment and temperature regulation, but this does not explain the absence of mucous glands. D: The presence of strata of cells in the outer skin layer is related to its protective function and does not directly influence the absence of mucous glands.

Correct Answer: B

Rationale: The correct answer is B: Perineal glands. Perineal glands are scent glands found in animals to produce pheromones. These glands are responsible for emitting scents used in communication and territorial marking. Zeis glands are sebaceous glands in the eyelids, Ceruminous glands produce earwax, and Sweat glands produce sweat for thermoregulation. Therefore, perineal glands are the only glands specifically known for producing scents.
