Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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 3 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 4 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 5 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.
