Questions About the Integumentary System Questions
Question 1 of 5
White blood cells (WBCs) are most abundant in the:
Correct Answer: C
Rationale: The correct answer is C, dermis. White blood cells play a crucial role in the immune system, primarily located in the blood and lymphatic system. The dermis contains a network of blood vessels and lymphatic vessels, making it a hub for white blood cells to travel and function effectively in immune responses. Choices A and B are incorrect as they are primarily related to skin layers rather than immune cell distribution. Choice D is incorrect as while white blood cells can be found in various tissues, the highest concentration is typically in the dermis due to its rich blood and lymph supply.
Question 2 of 5
To reduce an incapacitated patient's risk of developing a pressure ulcer, the nurse should reposition the patient at least every 4 hours.
Correct Answer: B
Rationale: The correct answer is B: FALSE. Repositioning an incapacitated patient every 2 hours is recommended to reduce the risk of pressure ulcers, not every 4 hours. This frequent repositioning helps to relieve pressure on bony prominences and improves circulation. Repositioning every 4 hours may increase the risk of pressure ulcer development. Choice A is incorrect because repositioning every 4 hours is not sufficient to prevent pressure ulcers. Choices C and D are not applicable as they are left blank.
Question 3 of 5
Which complication may be caused by sepsis in burns?
Correct Answer: C
Rationale: The correct answer is C: Paralytic ileus. Sepsis can lead to systemic inflammation, causing paralysis of the intestines, known as paralytic ileus. This results in decreased bowel motility and can lead to symptoms such as abdominal pain, bloating, and vomiting. Incorrect choices: A: Diarrhea - Sepsis typically causes an inflammatory response leading to increased fluid movement into the intestines, resulting in diarrhea rather than constipation. B: Constipation - Sepsis usually leads to increased bowel movements rather than constipation due to the body's attempt to eliminate toxins. D: Curling ulcer - Curling ulcer is a stress-related mucosal injury that occurs in response to severe burns, not directly related to sepsis in burns.
Question 4 of 5
Which finding would a nurse expect when assessing a diabetic client receiving long-term corticosteroid therapy admitted to the hospital with leg ulcers?
Correct Answer: D
Rationale: The correct answer is D: Inadequate wound healing. Corticosteroids can impair the body's ability to heal wounds by suppressing the immune response and reducing inflammation. This effect is particularly concerning for diabetic patients who already have impaired wound healing due to their condition. Weight loss (A) is not typically associated with corticosteroid therapy, and diabetic patients are more prone to hyperglycemia rather than hypoglycemia (B). Corticosteroids can actually lead to increased blood pressure, so decreased blood pressure (C) would be an unexpected finding in this scenario.
Question 5 of 5
Which intervention will decrease the occurrence of pressure ulcers when caring for a client with quadriplegia?
Correct Answer: B
Rationale: The correct answer is B: Frequent repositioning of the client. Repositioning helps to relieve pressure on vulnerable areas, reducing the risk of pressure ulcers. Regularly changing the client's position ensures that no single area is consistently bearing weight, promoting circulation and skin integrity. Avoiding leg massages (A) can be detrimental as massages can improve circulation. Increasing fiber content in food (C) and encouraging weight-bearing exercises (D) may be beneficial for overall health but do not directly address pressure ulcer prevention in quadriplegic clients.
