Nursing Elites

1. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

2. A group of clients is being instructed by a nurse regarding nutrition. The teaching should state that which of the following groups of foods contains the highest level of carbohydrates?

• A. Milk, eggs, and cheese
• B. Butter, oils, and avocados
• C. Rice, potatoes, and oranges
• D. Chicken, green beans, and apples

Correct answer: C

Rationale: The correct answer is C: Rice, potatoes, and oranges. These foods are rich in carbohydrates. Choice A (Milk, eggs, and cheese) contains minimal carbohydrates as they are primarily sources of protein and fat. Choice B (Butter, oils, and avocados) contains very little to no carbohydrates as they are high in fats. Choice D (Chicken, green beans, and apples) also contains minimal carbohydrates, with protein and fiber being more prominent in these foods.

3. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

• A. stomach
• B. pancreas
• C. large intestine
• D. small intestine

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

4. 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.

5. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

• 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: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.
