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.

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.

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.

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.

Correct Answer: C

Rationale: The correct answer is C: Median plane. The median plane is also known as the midsagittal plane, which divides the body or an organ into equal left and right halves. This plane passes through the midline of the body, specifically through the sagittal suture of the skull and the umbilicus. The transverse plane (A) divides the body into superior and inferior portions, the horizontal plane (B) is another term for the transverse plane, and the oblique plane (D) cuts the body at an angle, not into equal left and right sides. Therefore, the median plane is the correct choice for this scenario.
