Integumentary System CPT Questions and Answers Questions
Question 1 of 5
What is the function of the hypodermis?
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.
Question 2 of 5
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.
Question 3 of 5
Epidermis of skin in rabbit is originated from-
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.
Question 4 of 5
Pigmented cells are found amongst the cells of -
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.
Question 5 of 5
Which layer of skin of hands is highly developed in labourers who work hard with their hands-
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.
