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. The nurse is planning education about appropriate protein food choices for a client who has recently been prescribed a renal diet. Which protein food items should the nurse include in the education?

• A. Yogurt, seeds, and lentils
• B. Beef, bacon, and nuts
• C. Peanut butter, beans, and peas
• D. Poultry, eggs, and fish

Correct answer: D

Rationale: The correct answer is D: Poultry, eggs, and fish. These protein sources are high-quality proteins suitable for a renal diet as they provide essential amino acids without excessive amounts of potassium or phosphorus. Choice A, yogurt, seeds, and lentils, may be high in potassium and phosphorus, which could be restricted in a renal diet. Choice B, beef, bacon, and nuts, are also high in phosphorus and may not be ideal for a renal diet. Choice C, peanut butter, beans, and peas, are high in potassium and phosphorus, making them less suitable for a renal diet.

3. Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.

• 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 false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.

4. 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.

5. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
