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 types of fiber is not a carbohydrate?

• A. gums
• B. lignin
• C. pectin
• D. cellulose

Correct answer: B

Rationale: Lignin is the correct answer because it is a type of fiber that is not a carbohydrate and provides structure to plant cell walls. Gums (choice A), pectin (choice C), and cellulose (choice D) are all types of dietary fiber that are carbohydrates. Gums are a type of soluble fiber, pectin is found in fruits and is a soluble fiber, and cellulose is a type of insoluble fiber found in plant cell walls.

3. One characteristic of an essential fatty acid is that it:

• A. comes from a plant source.
• B. comes from an animal source.
• C. is not manufactured by the body.
• D. is manufactured by the body.

Correct answer: C

Rationale: The correct answer is C because essential fatty acids are not manufactured by the body and must be obtained through the diet. Choice A is incorrect because essential fatty acids can come from plant sources as well. Choice B is incorrect as essential fatty acids are primarily derived from plant sources. Choice D is incorrect because essential fatty acids cannot be produced by the body. Therefore, the only accurate statement is that essential fatty acids are not manufactured by the body.

4. Which component of protein contains nitrogen?

• A. Amino group
• B. Carboxyl group
• C. Peptide bond
• D. Side chain

Correct answer: A

Rationale: The correct answer is the amino group. Amino groups are functional groups found in amino acids, which are the building blocks of proteins. These groups contain nitrogen and are essential for the structure and function of proteins. The carboxyl group (choice B) contains carbon, oxygen, and hydrogen, while the peptide bond (choice C) is a covalent bond formed between amino acids in a protein chain. The side chain (choice D) refers to the unique chemical structure attached to the central carbon of an amino acid and varies among different amino acids, but it does not specifically contain nitrogen.

• A. cancer.
• B. diabetes.
• C. hypertension.
