Nursing Elites

1. The primary responsibility for nutrition care of people in the community belongs to the:

• A. community physician.
• B. public health nurse.
• C. public health nutritionist.
• D. registered dietitian.

Correct answer: C

Rationale: Public health nutritionists work within communities to ensure that populations have access to nutritional resources. They focus on promoting good nutrition, developing programs, and educating the public about healthy eating habits. While community physicians, public health nurses, and registered dietitians may also play roles in promoting nutrition in the community, the primary responsibility for nutrition care typically falls under the purview of public health nutritionists.

2. Which of the following are macronutrients?

• A. Minerals.
• B. Proteins.
• C. Vitamins.
• D. Enzymes.

Correct answer: B

Rationale: Proteins are indeed macronutrients, along with carbohydrates and fats. Macronutrients are nutrients that provide energy and are required in large amounts by the body. Minerals and vitamins are considered micronutrients, as they are needed in smaller quantities. Enzymes, on the other hand, are not nutrients but rather biological molecules that act as catalysts in biochemical reactions.

3. What is one useful outcome of keeping a record of everything you eat and drink for a day?

• A. Precise estimates of portion sizes.
• B. Determination of appropriate energy intake.
• C. Estimation of supplement needs.
• D. Increased awareness of personal food patterns.

Correct answer: D

Rationale: The correct answer is D: Increased awareness of personal food patterns. Keeping a food record is beneficial as it helps individuals become more mindful of their eating habits and food choices. This awareness can lead to identifying patterns, triggers, and areas for improvement in one's diet. Choices A, B, and C are incorrect because the primary benefit of keeping a food record is not about precise estimates of portion sizes, determining energy intake, or estimating supplement needs, but rather about developing a deeper understanding of personal food patterns.

4. Proteins from plant sources such as grains, nuts, and legumes are classified as:

• A. incomplete.
• B. complete.
• C. indispensable.
• D. dispensable.

Correct answer: A

Rationale: The correct answer is A: 'incomplete.' Proteins from plant sources like grains, nuts, and legumes are considered incomplete because they often lack one or more essential amino acids required by the body. Choice B, 'complete,' is incorrect because complete proteins contain all essential amino acids in adequate amounts. Choice C, 'indispensable,' is incorrect as it refers to essential amino acids rather than the classification of plant proteins. Choice D, 'dispensable,' is also incorrect as it implies that these proteins are not necessary, which is not the case.

5. Which lipoprotein increases the risk of cardiovascular disease?

• A. Low-density lipoprotein (LDL)
• B. High-density lipoprotein (HDL)
• C. Very low-density lipoprotein (VLDL)
• D. Chylomicrons

Correct answer: A

Rationale: The correct answer is A: Low-density lipoprotein (LDL). LDL is often referred to as 'bad cholesterol' because it can lead to plaque buildup in arteries, increasing the risk of cardiovascular disease. High-density lipoprotein (HDL) is considered 'good cholesterol' as it helps remove LDL from the arteries, reducing the risk of cardiovascular issues. Very low-density lipoprotein (VLDL) and chylomicrons are also lipoproteins that transport fats in the bloodstream, but they are not as strongly associated with an increased risk of cardiovascular disease as LDL.
