Integumentary System Questions Questions
Question 1 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.
Question 2 of 5
What layer of the epidermis is most superficial?
Correct Answer: A
Rationale: The correct answer is A: Stratum corneum. The stratum corneum is the most superficial layer of the epidermis, consisting of dead, flattened keratinocytes. It acts as a protective barrier against external factors. The other choices are incorrect because the stratum lucidum is found only in thick skin, the stratum granulosum is the layer where keratinocytes start to flatten and lose their nuclei, and the stratum basale is the deepest layer where active cell division occurs.
Question 3 of 5
What is the laser attracted to in hair removal?
Correct Answer: B
Rationale: The correct answer is B: Melanin. Melanin is the pigment responsible for the color of the hair and skin. Laser hair removal targets melanin in the hair follicles, absorbing the laser energy and converting it to heat, which damages the follicle and inhibits future hair growth. Keratin (A) is a protein in the hair shaft, not the target for laser removal. Collagen (C) is a protein in the skin, not involved in hair removal. Sebum (D) is a natural oil produced by the skin glands, not targeted by laser hair removal.
Question 4 of 5
In an industrial accident, a male client that weighs 155 lb. (70 kg) sustained full thickness burns over 40% of his body. He is in the burn unit receiving fluid resuscitation. Which observation shows that the fluid resuscitation is benefiting the client?
Correct Answer: A
Rationale: Rationale: Urine output above 100 ml/hour indicates adequate perfusion and kidney function, a key indicator of effective fluid resuscitation in burn patients. This ensures proper circulation and helps prevent acute kidney injury. In contrast, choices B, C, and D are signs of inadequate fluid resuscitation: low blood pressure (hypotension), high pulse rate (tachycardia), and increased respiratory rate (tachypnea) are signs of hypovolemic shock and inadequate tissue perfusion.
Question 5 of 5
Nurse Melinda is caring for an elderly bedridden adult. To prevent pressure ulcers, which intervention should the nurse include in the plan of care?
Correct Answer: A
Rationale: The correct answer is A: Post a turning schedule at the client's bedside. Turning the bedridden adult regularly helps redistribute pressure and prevents pressure ulcers. This intervention promotes blood flow and prevents tissue damage. Choice B is incorrect as lotion application does not address the root cause of pressure ulcers. Choice C is incorrect as increasing fluid intake alone does not prevent pressure ulcers. Choice D is incorrect as ring cushions may provide temporary relief but do not address the need for regular repositioning to prevent pressure ulcers.
