1. Milk and other dairy products are preferred sources of calcium because lactose enhances calcium absorption.

A. Both the statement and the reason are correct and related.
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: Both the statement and the reason are correct and related. Milk and other dairy products are indeed preferred sources of calcium because they supply most of the available calcium. Additionally, lactose present in dairy products enhances calcium absorption, making them even more efficient sources of this essential mineral. The statement correctly identifies dairy products as preferred sources of calcium, and the reason explains how lactose contributes to better calcium absorption. The other choices are incorrect as they do not accurately assess the relationship between lactose, calcium absorption, and the preference for dairy products as sources of calcium.

2. Why are blood glucose levels high in type 1 diabetes?

A. The urinary excretion of glucose is impaired
B. The lean body mass is metabolized to produce glucose via gluconeogenesis
C. The absorption of glucose from the gastrointestinal tract is more efficient
D. There is insufficient insulin to facilitate the transport of glucose into the cells

Correct answer: D

Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.

3. The nurse is assessing a client with a new diagnosis of Listeria food poisoning. What action should the nurse take first?

A. Educate the client on safe food practices.
B. Start a traceback to identify the source of the outbreak.
C. Report the case to the county board of health.
D. Ask the client if they have consumed any unpasteurized products.

Correct answer: D

Rationale: The correct first action for the nurse to take when assessing a client with a new diagnosis of Listeria food poisoning is to inquire if the client has consumed any unpasteurized products. This is crucial because Listeria contamination is often associated with unpasteurized dairy products and undercooked meats. Educating the client on safe food practices (Choice A) is important but not the priority at this initial assessment stage. Starting a traceback to identify the source of the outbreak (Choice B) and reporting the case to the county board of health (Choice C) are necessary actions but should come after gathering information directly from the client regarding potential exposure to high-risk foods.

4. Which of the following is not correct?

A. energy density is a comparison of energy (kcals) content to the weight of food
B. if a food product contains a 15% daily value of calcium, that product is said to be a low source of calcium
C. MyPlate illustrates the 5 food groups
D.

Correct answer: B

Rationale: A product with 15% Daily Value (DV) of calcium is considered a good source, not a low source. Typically, anything 10-19% DV is considered a good source.

5. Select all that apply. To lower LDL levels, you should:

A. consume minimal amounts of hydrogenated and saturated fats
B. consume more insoluble fibers than soluble fibers
C. consume alcohol in moderate levels
D. engage in regular physical activity

Correct answer: A

Rationale: To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.
