1. High intakes of which of the following interfere with copper absorption and can lead to a deficiency?
- A. chromium
- B. sodium
- C. zinc
- D. manganese
Correct answer: C
Rationale: The correct answer is C, zinc. High intakes of zinc can interfere with copper absorption, potentially leading to copper deficiency. Copper is essential for various bodily functions, including iron metabolism. Choice A, chromium, is incorrect because chromium does not interfere with copper absorption. Choice B, sodium, and Choice D, manganese, are also incorrect as they do not interfere with copper absorption.
2. Is it correct that eliminating sucrose from the diet leads to a significant reduction in dental caries, and that the best advice is to consume sugar in moderation and limit the frequency of sugar exposure?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: D
Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.
3. The GAUGE size in ET tubes determines:
- A. The external circumference of the tube
- B. The internal diameter of the tube
- C. The length of the tube
- D. The tube’s volumetric capacity
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
4. Why are LDLs known as the 'bad' type of cholesterol?
- A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct answer: A
Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

- B. Alcoholize the self sealing port, obtain a sterile syringe and draw the specimen on the self sealing port
- C. Disconnect the drainage bag, obtain a sterile syringe and draw the specimen from the drainage bag
- D. Disconnect the tube, obtain a sterile syringe and draw the specimen from the tube
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
