Integumentary System Exam Questions Questions
Question 1 of 5
A nurse is explaining the importance of sunlight on the skin to a woman with decreased mobility who rarely leaves her house. The nurse would emphasize that ultraviolet light helps to synthesize what vitamin?
Correct Answer: B
Rationale: The correct answer is B: D. Ultraviolet light helps the skin to synthesize vitamin D. When sunlight hits the skin, it triggers a reaction that produces vitamin D. This is important for maintaining healthy bones and immune system function. Choice A: E is incorrect because vitamin E is not synthesized by sunlight. Choice C: A is incorrect because vitamin A is not synthesized by sunlight. Choice D: C is incorrect because vitamin C is not synthesized by sunlight.
Question 2 of 5
Patients with burns may have mesh grafts or sheet grafts. Which of the following sites is most likely to have a sheet graft applied?
Correct Answer: B
Rationale: The correct answer is B: Face. Sheet grafts are typically used on areas where a smooth, even surface is desired, such as the face. Mesh grafts, on the other hand, are often used on areas that need more flexibility and conformity, like the arms and legs. Chest may also require mesh grafts due to its irregular shape. So, face is the most likely site for a sheet graft due to the need for aesthetic outcomes and minimal scarring.
Question 3 of 5
While changing the dressing on a burned arm the patient complains of feeling cold and having extreme pain. However, the patient asks the nurse to not apply so much pressure when wrapping gauze around the limb. What should these findings indicate to the nurse?
Correct Answer: C
Rationale: The correct answer is C: Encapsulated nerve endings in the arm are intact. This is indicated by the fact that the patient is experiencing extreme pain (associated with free nerve endings) but can still differentiate pressure sensation (associated with encapsulated nerve endings). If all nerves were damaged (Choice A), the patient would not feel any sensation. If free nerve endings were injured (Choice B), the patient would not feel pain. If encapsulated nerve endings were injured (Choice D), the patient would not be able to differentiate pressure sensation.
Question 4 of 5
A nurse is caring for a patient who had a right below-the-knee amputation (BKA). The nurse recognizes the importance of implementing measures that focus on preventing flexion contracture of the hip and maintaining proper positioning. Which of the following measures will best achieve these goals?
Correct Answer: A
Rationale: The correct answer is A: Encouraging the patient to turn from side to side and to assume a prone position. This measure is essential for preventing hip flexion contractures after a below-the-knee amputation. Turning from side to side and assuming a prone position help in maintaining proper positioning and preventing hip flexion contractures by stretching the hip extensors and preventing the hip from being in a prolonged flexed position. Choice B is incorrect because initiating ROM exercises of the hip and knee 10 to 12 weeks after the amputation may be too late to prevent contractures. Choice C is incorrect as minimizing movement of the flexor muscles of the hip can actually lead to contractures. Choice D is also incorrect as sitting in a chair for extended periods can promote hip flexion contractures.
Question 5 of 5
A patient who has had an amputation is being cared for by a multidisciplinary rehabilitation team. What is the primary goal of this multidisciplinary team?
Correct Answer: D
Rationale: The correct answer is D: Promote the patient's highest possible level of function. The primary goal of a multidisciplinary rehabilitation team caring for a patient who has had an amputation is to help the patient achieve their maximum functional ability and independence. This goal involves various specialists working together to provide comprehensive care tailored to the patient's specific needs. Maximizing efficiency of care (A) is important but not the primary goal. Ensuring holistic healthcare (B) is valuable but not the primary focus. Facilitating adjustment to a new body image (C) is important, but the primary goal is to promote the patient's functional abilities.
