1. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.
- A. water
- B. protein
- C. fat
- D. carbs
Correct answer: C
Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.
2. Which breakfast item should be recommended for a vegan adolescent to combine protein?
- A. Bagel with cream cheese
- B. Wheat toast with jelly
- C. Oatmeal pancakes with peanut butter
- D. Eggs with tofu bacon
Correct answer: C
Rationale: Oatmeal pancakes with peanut butter provide a protein combination suitable for a vegan diet.
3. This study, which is an in-depth study of one boy, is a:
- A. case study
- B. longitudinal study
- C. cross-sectional study
- D. evaluative study
Correct answer: A
Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.
4. What physiologic role does calcium play in the body?
- A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
- B. Calcium homeostasis, structural integrity of heart muscle
- C. No known metabolic function, caries-preventing properties
- D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.
Correct answer: A
Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.
5. Which mineral-containing amino acids help to form the shape of proteins?
- A. phosphorus
- B. sulfur
- C. selenium
- D. iron
Correct answer: B
Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.
