Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 4
What is a skin graft that is used to transfer skin and subcutaneous tissue to large areas of deep tissue destruction called?
Correct Answer: A
Rationale: Rationale for Correct Answer (A: Skin flap): 1. A skin flap involves transferring skin and subcutaneous tissue to repair extensive tissue loss. 2. Skin flaps have a direct blood supply, ensuring better survival in large areas of deep tissue destruction. 3. The term "skin graft" usually refers to a procedure where skin is transplanted without its own blood supply. 4. Therefore, a skin flap, with its vascular supply intact, is the appropriate choice. Summary of Incorrect Choices: B: Free graft - Incorrect because free grafts lack a direct blood supply and are more suitable for smaller areas. C: Soft tissue extension - Incorrect as it does not specifically describe the technique of transferring skin and subcutaneous tissue. D: Free graft with vascular anastomoses - Incorrect as this refers to a different technique involving connecting blood vessels, not commonly used for large areas of deep tissue destruction.
Question 2 of 4
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 3 of 4
Mrs. Reagan has just been treated for basal cell carcinoma of the upper lip by surgical excision. It would be most important to teach her to
Correct Answer: D
Rationale: The correct answer is D: avoid unnecessary exposure to the sun. This is crucial because excessive sun exposure is a major risk factor for developing skin cancers like basal cell carcinoma. By avoiding the sun, Mrs. Reagan can reduce her risk of developing further skin cancers. Observing for recurrence (choice A) is important but not as immediate as sun protection. Systemic chemotherapy (choice B) is not typically used for basal cell carcinoma. While stopping smoking (choice C) is important for overall health, it is not directly related to preventing the recurrence of basal cell carcinoma.
Question 4 of 4
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.
