Integumentary System Questions Questions
Question 1 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 2 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 3 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 4 of 5
The nurse notes that a patient's wound is weeping and edematous. In which phase of healing is this wound?
Correct Answer: D
Rationale: In this case, the weeping and edematous wound indicates an inflammatory phase. This phase involves the body's initial response to injury, characterized by redness, swelling, heat, and pain. The weeping suggests fluid accumulation due to increased vascular permeability. The proliferative phase focuses on tissue repair and regeneration, while maturation involves tissue remodeling and scar formation. Hemostasis is the immediate response to stop bleeding. Therefore, the correct answer is D.
Question 5 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.
