Integumentary System Questions Questions
Question 1 of 5
A new patient has come to the dermatology clinic to be assessed for a reddened rash on his abdomen. What diagnostic test would most likely be ordered to identify the causative allergen?
Correct Answer: C
Rationale: The correct answer is C: Patch testing. Patch testing is used to identify contact allergens causing skin reactions, such as rashes. It involves applying small amounts of potential allergens onto the skin and observing for a reaction. This test is ideal for identifying causative allergens in cases of allergic contact dermatitis. A: Skin scrapings are used to diagnose fungal or parasitic infections, not allergens. B: Skin biopsy is used to diagnose skin conditions like skin cancer or inflammatory skin diseases, not allergens. D: Tzanck smear is used to diagnose viral infections like herpes, not allergens.
Question 2 of 5
The nurse is caring for a patient with an electrical injury. The nurse understands that patients with electrical injury are at a high risk for acute kidney injury secondary to:
Correct Answer: D
Rationale: The correct answer is D: release of myoglobin from injured tissues. Electrical injuries can cause muscle damage, leading to the release of myoglobin into the bloodstream, which can cause kidney damage by blocking renal tubules. This can result in acute kidney injury. Other choices are incorrect because hypervolemia from burn resuscitation does not directly lead to acute kidney injury, ureteral stones are not directly related to electrical injuries, and nephrotoxic antibiotics are not typically used solely for prevention of infection in electrical injury cases.
Question 3 of 5
The nurse is documenting findings from collecting data with a patient. What term should the nurse use to document transverse depressions in the nails?
Correct Answer: B
Rationale: The correct term for transverse depressions in the nails is Beau's lines. Beau's lines are caused by a temporary disruption in nail growth due to illness or stress. Paronychia is an infection around the nail bed, Koilonychias is spoon-shaped nails associated with iron deficiency anemia, and Splinter hemorrhages are tiny blood clots under the nails. Beau's lines specifically describe transverse depressions, making it the most appropriate term in this context.
Question 4 of 5
A patient with a simple arm fracture is receiving discharge education from the nurse. What would the nurse instruct the patient to do?
Correct Answer: B
Rationale: The correct answer is B: Engage in exercises that strengthen the unaffected muscles. This instruction is important for maintaining overall muscle strength and preventing muscle atrophy in the unaffected arm. Strengthening exercises can also aid in the recovery process and help prevent future injuries. A: Elevating the affected extremity to shoulder level is not necessary for a simple arm fracture and may not contribute significantly to the healing process. C: Applying topical anesthetics is not typically part of discharge instructions for a simple arm fracture and may not be relevant to the patient's care. D: Avoiding analgesics is not recommended as pain management is important for the patient's comfort and well-being during the healing process.
Question 5 of 5
An older adult patient has fallen in her home and is brought to the emergency department by ambulance with a suspected fractured hip. X-rays confirm a fracture of the left femoral neck. When planning assessments during the patient's presurgical care, the nurse should be aware of the patient's heightened risk of what complication?
Correct Answer: B
Rationale: The correct answer is B: Avascular necrosis. A fractured femoral neck can disrupt blood flow to the head of the femur, leading to avascular necrosis (bone death). This complication can result in further pain and disability. Osteomyelitis (A) is an infection of the bone, which is not directly linked to a fractured femoral neck. Phantom pain (C) is pain perceived in a body part that is no longer there, typically in amputees, not related to a fractured hip. Septicemia (D) is a serious bloodstream infection, which may be a complication of surgery or prolonged hospitalization, but not directly related to a fractured hip.
