Integumentary System Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse notes that an older patient complains of always feeling cold. Which age-related change to the skin could be causing this in the patient?
Correct Answer: B
Rationale: The correct answer is B: Decreased subcutaneous tissue. As people age, they tend to lose subcutaneous fat, which acts as insulation. This loss of fat can result in feeling colder more easily. Fewer protein stores (A) and reduced levels of immune cells (C) are not directly related to feeling cold. Slower blood flow to the skin layers (D) can contribute to temperature regulation issues but is not the primary reason for feeling cold in older adults.
Question 5 of 5
The nurse is caring for a patient with 70% total body surface area chemical burns. Which approach should the nurse anticipate to meet this patient's nutritional needs?
Correct Answer: A
Rationale: Rationale: Option A, parenteral nutrition, is the correct approach for a patient with extensive burns as it bypasses the gastrointestinal tract and provides essential nutrients directly into the bloodstream. This is crucial in cases of severe burns to prevent complications such as malnutrition and support the body's healing process. Options B and C involve feeding through the gastrointestinal tract, which may not be suitable for such extensive burns due to potential complications like GI intolerance or absorption issues. Option D, six small high-calorie meals per day, is not appropriate for a patient with extensive burns as the digestive system may not be able to handle normal oral intake.
