1. Which of the following are considered micronutrients?
- A. Fats.
- B. Proteins.
- C. Vitamins.
- D. Carbohydrates.
Correct answer: C
Rationale: Micronutrients are essential nutrients needed by the body in small quantities to support various bodily functions. Vitamins fall under this category as they play crucial roles in metabolism, immune function, and overall health. While fats, proteins, and carbohydrates are essential macronutrients required in larger amounts for energy and growth, they are not classified as micronutrients. Therefore, the correct answer is C.
2. 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.
3. The process of breaking down body protein into amino acids for energy is known as:
- A. Deamination.
- B. Transamination.
- C. Transcription.
- D. Catabolism.
Correct answer: D
Rationale: The correct answer is D: Catabolism. Catabolism involves the breakdown of body proteins into amino acids to be used as energy when there is an inadequate dietary intake. Choices A and B, deamination and transamination, involve the removal and transfer of amino groups, respectively, but not the breakdown of body proteins. Choice C, transcription, is a process in genetics where DNA is used to create mRNA, not related to breaking down body proteins.
4. Why are diets that contain less than 10% of kcalories as fat not recommended?
- A. Intake of carbohydrates would not necessarily be too high.
- B. This would not necessarily require excessive use of fat replacers.
- C. The diet would not provide adequate essential fatty acids.
- D. Intake of essential fatty acids would be too low.
Correct answer: D
Rationale: Diets that contain less than 10% of kcalories as fat are not recommended because they would lead to inadequate intake of essential fatty acids, which are crucial for various bodily functions like hormone production, brain function, and cell membrane structure. Option A is incorrect because reducing fat intake does not necessarily mean increasing carbohydrate intake excessively. Option B is incorrect as it introduces a new concept of using fat replacers, which is not directly related to the issue of essential fatty acid intake. Option C is incorrect as the primary concern with low-fat diets is the insufficiency of essential fatty acids, not the adequacy of them.
5. 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.
