Nursing Elites

1. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

• 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: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

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. Which of the following nutrients does not provide energy?

• A. Proteins
• B. Carbohydrates
• C. Fats
• D. Vitamins

Correct answer: D

Rationale: Proteins, carbohydrates, and fats are macronutrients that provide energy in the form of calories when consumed and metabolized by the body. Each gram of protein or carbohydrate provides about 4 calories, and each gram of fat provides about 9 calories. On the other hand, vitamins do not provide energy or calories. They are micronutrients that are essential for various biochemical and physiological processes in the body, including the metabolism of macronutrients. However, they do not contribute directly to the energy supply. Therefore, the correct answer is 'D: Vitamins'. Choices A, B, and C (Proteins, Carbohydrates, and Fats) are incorrect because they are macronutrients that do provide energy/calories when metabolized.

4. What instruction should a nurse include when teaching a client who has recently been prescribed a low-sodium diet?

• A. Avoid foods such as smoked meats and frozen dinners.
• B. Select foods with less than 4g of sodium as indicated on food labels.
• C. Use soy sauce for flavoring foods instead of table salt.
• D. Processed and prepared foods are typically low in sodium.

Correct answer: A

Rationale: The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.

5. A client who has dumping syndrome following a hemi-colectomy should avoid which of the following foods when receiving nutritional teaching from a nurse?

• A. Rice
• B. Poached eggs
• C. Fresh apples
• D. White bread

Correct answer: C

Rationale: Fresh apples should be avoided by a client with dumping syndrome following a hemi-colectomy because they are high in fiber and can exacerbate gastrointestinal symptoms such as diarrhea and bloating. Rice and poached eggs are good options as they are easily digestible and less likely to trigger dumping syndrome symptoms. White bread is also preferable over whole grain bread due to its lower fiber content, making it a better choice for individuals with dumping syndrome.
