Which recommendation would a nurse include to a client with psoriasis when providing health teaching concerning skin care at home?

Correct Answer: C

Rationale: The correct answer is C. Applying moisturizing lotion several times a day is recommended for clients with psoriasis to help maintain skin hydration and reduce itching and irritation. It helps to soothe and protect the skin barrier. Showering twice a day (choice A) can strip the skin of natural oils, exacerbating dryness. Soaking in hot water (choice B) can worsen inflammation and dry out the skin. Covering affected areas when in contact with others (choice D) may be necessary for infection control but does not address the primary skin care needs of psoriasis.

Correct Answer: C

Rationale: The correct answer is C: To store energy. The hypodermis serves as a storage site for fat, which acts as an energy reserve for the body. It helps to insulate the body and regulate temperature indirectly, but its primary function is energy storage. A: While the hypodermis does provide some protection and cushioning, its main function is not to protect the body from the environment. B: While the hypodermis does help with insulation, its function is not primarily to regulate body temperature. D: While the hypodermis does have multiple functions, its primary role is energy storage, so not all of the above are correct.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." Stem cell therapy can regenerate damaged skin cells, 3D printing can create customized skin grafts, and nanotechnology can deliver drugs directly to affected areas. Each technology plays a crucial role in improving the treatment of skin diseases and injuries by addressing different aspects of the healing process. Choosing only one option would limit the scope and effectiveness of treatment options available.

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: C

Rationale: The epidermis of the skin in a rabbit originates from the ectoderm. During embryonic development, the ectoderm gives rise to the outermost layer of the skin, which includes the epidermis. The ectoderm is the primary germ layer that forms the skin, nervous system, and other structures derived from the outer layer of the embryo. The endoderm gives rise to the innermost layer of the skin, while the mesoderm forms the middle layer. Therefore, the correct answer is C (Ectoderm). Choices A, B, and D are incorrect because the epidermis does not originate from the endoderm, mesoderm, or all germ layers, but specifically from the ectoderm during embryonic development.
