Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
In assessing a patient’s skin it is particularly important to identify any lesions that could be malignant. Which of the following lesions would be suggestive of malignant melanoma?
Correct Answer: B
Rationale: The correct answer is B because a circular, brown-black lesion with elevated, palpable margins is characteristic of malignant melanoma. Melanomas often have irregular borders and colors, and they may be raised. Choice A is more indicative of a vascular lesion. Choice C describes a common mole. Choice D is more typical of a dermatofibroma. In summary, B is the correct choice due to its specific characteristics associated with malignant melanoma, while the other choices describe different types of skin lesions.
Question 2 of 5
In preparation for his getting out of bed to walk, you are applying an elastic bandage to Mr. Moore’s freshly healed burned leg to provide good venous return and prevent blistering of the new skin. It is most important to
Correct Answer: B
Rationale: The correct answer is B: leave the heel exposed. This is important because when applying an elastic bandage to a freshly healed burned leg, leaving the heel exposed helps to prevent constriction of circulation and allows for proper venous return. By leaving the heel exposed, pressure is not applied directly to the Achilles tendon or the heel area, which could impede circulation and cause discomfort. This also helps to prevent blistering of the new skin by ensuring proper blood flow and reducing the risk of pressure ulcers. Choice A is incorrect because a figure-8 style of wrap may not provide the necessary support and could potentially constrict circulation. Choice C is incorrect because applying the bandage too loosely may not provide the required support and could lead to inadequate compression. Choice D is incorrect because removing the bandage as soon as the patient starts to walk can compromise the healing process and increase the risk of injury.
Question 3 of 5
Keratinocyte is to epidermis as ___ is to dermis.
Correct Answer: A
Rationale: The correct answer is A: fibroblast. Keratinocytes are the predominant cells in the epidermis responsible for producing keratin, a protein that provides structural support and protection to the skin. Similarly, fibroblasts are the main cells in the dermis that produce collagen and elastin fibers, which give the skin its strength and elasticity. Fibrocytes (choice C) are inactive fibroblasts, and dermoblasts (choice B) and dermocytes (choice D) are not recognized cell types in dermatology. Therefore, fibroblast is the most appropriate analogy for the relationship between keratinocyte and epidermis.
Question 4 of 5
Which statement is NOT true of the subcutaneous tissue?
Correct Answer: A
Rationale: The correct answer is A because the subcutaneous tissue is located below the dermis, not between the stratum corneum and muscles. The subcutaneous tissue is composed of adipose tissue and some areolar connective tissue. Adipose tissue stores triglycerides for energy storage and insulation. Mast cells in the subcutaneous tissue produce histamine in response to damage. Areolar connective tissue in the subcutaneous layer contains a matrix with various cells, including white blood cells. So, option A is incorrect as the subcutaneous tissue is not located between the stratum corneum and muscles.
Question 5 of 5
A 20-year-old patient is being seen in the dermatology clinic for a basal cell carcinoma on her eye. The nurse would expect the physician to complete which intervention?
Correct Answer: B
Rationale: The correct answer is B: Mohs' micrographic surgery. This technique is preferred for basal cell carcinoma on sensitive areas like the eye because it allows for precise removal of cancerous tissue layer by layer while sparing healthy tissue. It offers the highest cure rate and best cosmetic outcome. Electrosurgery (A) may not be as precise, Cryosurgery (C) is not ideal for tumors on the eye, and Radiation (D) is typically reserved for cases where surgery is not feasible.
