1. Which of the following is not correct?
- A. energy density is a comparison of energy (kcals) content to the weight of food
- B. if a food product contains a 15% daily value of calcium, that product is said to be a low source of calcium
- C. MyPlate illustrates the 5 food groups
- D.
Correct answer: B
Rationale: A product with 15% Daily Value (DV) of calcium is considered a good source, not a low source. Typically, anything 10-19% DV is considered a good source.
2. A client who is in her second trimester of pregnancy should increase her caloric intake by how many calories during this trimester?
- A. 110 cal/day
- B. 225 cal/day
- C. 340 cal/day
- D. 450 cal/day
Correct answer: C
Rationale: During the second trimester of pregnancy, it is recommended that a client increases their caloric intake by around 340 calories per day to support the growing needs of both the mother and the developing fetus. This additional intake helps ensure the proper nutrition and energy levels required during this crucial stage of pregnancy. Option A (110 cal/day) is too low to meet the increased demands. Option B (225 cal/day) is also below the recommended amount. Option D (450 cal/day) is higher than necessary and could lead to excessive weight gain, which is not ideal during pregnancy.
3. Which is NOT a classification of carbohydrate?
- A. Monosaccharides
- B. Disaccharides
- C. Polysaccharides
- D. Triglycerides
Correct answer: D
Rationale: The correct answer is D, Triglycerides. Triglycerides are a type of fat, not a carbohydrate. Monosaccharides, disaccharides, and polysaccharides are all classifications of carbohydrates based on the number of sugar units they contain. Monosaccharides are the simplest form with one sugar unit, disaccharides contain two sugar units, and polysaccharides have multiple sugar units linked together.
4. What physiologic role does magnesium 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: B
Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.
5. Lynn is an older adult who lives alone and has requested advice on how to eat a nutritious diet as cheaply as possible. One useful, practical tip for Lynn might be to _____.
- A. buy just a few pieces of fresh fruit at a time, in different stages of ripeness
- B. choose small boxes of frozen vegetables instead of large bags
- C. purchase pre-sliced or shredded cheese rather than whole pieces
- D. avoid buying certain foods in bulk, such as beans or dried legumes
Correct answer: A
Rationale: Buying a few pieces of fresh fruit at different stages of ripeness ensures that Lynn will have ripe fruit available over several days, reducing waste and cost. Choice B focuses on frozen vegetables but doesn't address the variety and ripeness factor like Choice A. Choice C is about cheese, which may not be as essential for a nutritious diet compared to fresh fruit. Choice D suggests avoiding certain foods in bulk, which might not be as relevant for maintaining a nutritious diet economically as the strategy in Choice A.
