Integumentary System Questions Questions
Question 1 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 2 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 3 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 4 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 5 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.
