Why must a nurse avoid disrupting bloodstains or tears on the clothing of a trauma client?

Correct Answer: C

Rationale: The correct answer is C because the clothing of a trauma client could potentially be considered evidence with legal implications. Preserving the bloodstains or tears on the clothing maintains the integrity of the evidence for forensic investigation or legal proceedings. Disrupting the bloodstains or tears could compromise the evidence and hinder any potential investigation or legal case. Choices A, B, and D are incorrect because the primary concern in this scenario is the legal implications and preservation of evidence, not ownership, repair, salvage, or minimizing trauma to family members.

Correct Answer: D

Rationale: The correct answer is D: Scurvy. Scurvy is caused by a deficiency in vitamin C, which is essential for collagen synthesis. Without enough vitamin C, collagen production is impaired, leading to symptoms like bleeding gums, fatigue, and joint pain. Incorrect Choices: A: Rickets is caused by a deficiency in vitamin D, not vitamin C. B: Marasmus is a severe form of malnutrition due to inadequate intake of calories and protein, not specifically vitamin C. C: Kwashiorkor is a form of severe acute malnutrition typically caused by inadequate protein intake, not vitamin C deficiency. In summary, the correct answer is D (Scurvy) because it directly relates to inadequate intake of vitamin C, while the other choices are associated with different nutrient deficiencies.

Correct Answer: C

Rationale: The correct answer is C: Lower cholesterol. Foods that help lower cholesterol typically include sources of soluble fiber, plant sterols, and healthy fats like omega-3 fatty acids. These components can lower LDL (bad) cholesterol levels and reduce the risk of heart disease. Fiber-rich foods (choice A) are beneficial for lowering cholesterol due to their ability to bind to cholesterol and remove it from the body. Reduce diabetic ketoacidosis (choice B) is unrelated to lowering cholesterol and is a serious complication of diabetes. Reduce the need for folate (choice D) is not directly related to cholesterol levels. Thus, the correct choice is C as it directly addresses the question about lowering cholesterol.

Correct Answer: A

Rationale: The correct answer is A: Inspect for visible pulsation. This is because an arteriovenous fistula for hemodialysis should have a visible pulsation, indicating proper blood flow. Palpating for thrill (B) and auscultating for bruit (C) are also common assessments for an arteriovenous fistula, but inspecting for visible pulsation is the most direct and reliable way to assess the patency of the fistula. Percussing for dullness (D) is not relevant in this context as it does not provide information about the vascular access site.

Correct Answer: A

Rationale: The correct answer is A because tolerance is a physiological phenomenon where the body adapts to a drug, requiring higher doses for the same effect. This is a common occurrence with opioids in chronic pain management. Choice B is incorrect as it refers to drug-seeking behavior, not tolerance. Choice C is incorrect because addiction and physical dependence are different concepts. Choice D is incorrect as it relates to a specific scenario of substance abuse alongside chronic pain, not the mechanism behind the need for increased opioid doses in chronic pain management.
