Questions on the Integumentary System Questions
Question 1 of 5
A patient has a circular, flat, reddened lesion about 5 cm in diameter on his ankle. To determine whether the lesion is related to blood vessel dilation, the nurse will
Correct Answer: D
Rationale: The correct answer is D: press firmly on the lesion. By pressing firmly on the lesion, the nurse can assess if the redness blanches, indicating that it is related to blood vessel dilation. Palpating pulses (choice A) would not provide information on blood vessel dilation. Checking skin temperature (choice B) may not directly indicate blood vessel dilation. Elevating the leg (choice C) may help with circulation but does not directly assess blood vessel dilation. Pressing on the lesion (choice D) is the best choice as it can help determine if the redness is due to blood vessel dilation.
Question 2 of 5
A patient with human immunodeficiency virus (HIV) has sought care because of the recent development of new skin lesions. The nurse should interpret these lesions as most likely suggestive of what?
Correct Answer: A
Rationale: The correct answer is A: A reduction in the patient's CD4 count. Skin lesions in HIV patients are often indicative of immunosuppression due to a decrease in CD4 cells, which are crucial for the immune system. As HIV progresses, CD4 count decreases, leading to increased susceptibility to infections and skin manifestations. Option B is incorrect because skin lesions are not directly related to viral load. Option C is incorrect as antiretroviral therapy typically improves skin conditions. Option D is incorrect as skin lesions in HIV are not typically related to changes in allergy status.
Question 3 of 5
The nurse is caring for a patient with a chemical burn injury. The priority nursing intervention is to:
Correct Answer: A
Rationale: The correct answer is A: remove the patient's clothes and flush the area with water. This is the priority intervention because it helps to stop the burning process by removing the source of the chemical and diluting it with water. Flushing the area with water helps to prevent further damage to the skin and underlying tissues. Removing the patient's clothes is important to prevent further exposure to the chemical. Choice B (apply saline compresses) is not the priority because simply applying compresses does not address the need to remove the source of the chemical and dilute it. Choice C (contact a poison control center) is not the priority as immediate action is needed to stop the burning process. Choice D (remove all jewelry) is important but not the priority compared to removing the patient's clothes and flushing the area with water.
Question 4 of 5
The nurse is assisting a patient who has a suspected diagnosis of tinea capitis (ringworm). For which diagnostic test should the nurse prepare the patient?
Correct Answer: D
Rationale: The correct answer is D: Wood's light examination. This test uses a special ultraviolet light to detect fungal infections like tinea capitis, which causes certain fungal species to fluoresce. The other choices are not appropriate for diagnosing tinea capitis. Patch test (A) is used to identify allergic contact dermatitis, scratch test (B) is used to identify immediate allergic reactions, and skin biopsy (C) is used to diagnose skin conditions like skin cancer or autoimmune diseases, not tinea capitis. Therefore, Wood's light examination is the most suitable test for diagnosing tinea capitis.
Question 5 of 5
Six weeks after an above-the-knee amputation (AKA), a patient returns to the outpatient office for a routine postoperative checkup. During the nurse's assessment, the patient reports symptoms of phantom pain. What should the nurse tell the patient to do to reduce the discomfort of the phantom pain?
Correct Answer: C
Rationale: Correct Answer: C Rationale: 1. Phantom pain is a common phenomenon post-amputation due to the brain still perceiving pain signals from the missing limb. 2. Opioid analgesics help manage phantom pain by blocking pain signals in the brain, providing relief. 3. Applying hot compresses (A) may not effectively address phantom pain, as it is neuropathic in nature. 4. Avoiding activity (B) does not address the underlying cause of phantom pain and may lead to physical deconditioning. 5. Elevating the level of the amputation site (D) does not directly target or alleviate phantom pain. Summary: Taking opioid analgesics as ordered (C) is the most appropriate intervention for managing phantom pain post-amputation, as it directly addresses the neuropathic nature of the pain and provides effective relief.
