Correct Answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

Correct Answer: B

Rationale: Cardiac cachexia is a condition characterized by severe weight loss and tissue wasting. This typically occurs in patients suffering from heart failure due to an increased energy expenditure and reduced appetite, which is why choice B is the correct answer. The other choices are incorrect as they do not accurately describe the symptoms of cardiac cachexia. Decreased physical activity (choice A) can be a result of many conditions, not specifically cardiac cachexia. Poor urine output and tissue edema (choice C) are more indicative of kidney problems rather than cardiac cachexia. Finally, cardiac arrhythmia and wet lung sounds (choice D) are symptoms related to other cardiac conditions, not specifically to cardiac cachexia.

Correct Answer: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

Correct Answer: B

Rationale: Folate (or folic acid) is crucial for the prevention of neural tube defects during pregnancy.

Correct Answer: C

Rationale: A kilocalorie count is the correct answer as it involves directly observing a client's food intake, which is often used in hospitals to accurately assess nutritional intake and ensure it meets dietary requirements. A food diary (Choice A) is typically self-reported by the client and not directly observed. A 24-hour recall (Choice B) is also usually self-reported and relies on a client's memory of the past 24 hours, which can be unreliable. A nutrient surveillance record (Choice D) is a broader term for tracking nutrient intake in a population and is not specific to the direct observation of an individual's food intake.
