Questions About the Integumentary System Questions
Question 1 of 5
Heat can separate the layers of the skin, and the fluid at the site is a:
Correct Answer: C
Rationale: The correct answer is C: blister. Heat can cause separation of skin layers leading to fluid accumulation, forming a blister. A callus is a thickened area of skin due to pressure or friction, not fluid accumulation. A nevus is a mole or birthmark, not related to heat. A bubo is a swollen lymph node, not related to skin separation due to heat.
Question 2 of 5
Which statement is NOT true of the skin and sunlight?
Correct Answer: B
Rationale: The correct answer is B because sunlight triggers the conversion of a precursor molecule in the skin, not a form of protein, into vitamin D. This process occurs in the skin when UV rays hit a compound called 7-dehydrocholesterol, converting it into vitamin D. Melanocytes produce melanin in response to UV exposure to protect the skin from damage caused by UV rays, making choice D true. Choices A and C are incorrect because UV rays can indeed cause mutations in skin cells and stimulate melanocytes to produce more melanin, respectively.
Question 3 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 4 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 5 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.
