1. A person who consumes mostly pre-packaged meals is likely consuming too much ____.
- A. iron
- B. zinc
- C. sodium
- D. riboflavin
Correct answer: C
Rationale: Pre-packaged meals often contain high levels of sodium, which can contribute to hypertension and other health issues when consumed in excess.
2. The most energy-rich nutrient is:
- A. carb
- B. fat
- C. protein
- D. water
Correct answer: B
Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.
3. A nurse is teaching a group of adults about nutrition. The nurse should include which of the following amounts as an appropriate daily intake of fiber for adult women?
- A. 5 to 10 g
- B. 10 to 15 g
- C. 20 to 35 g
- D. 40 to 50 g
Correct answer: 20 to 35 g
Rationale: The correct answer is 20 to 35 g. This range is the recommended daily intake of fiber for adult women. Fiber is essential for maintaining a healthy digestive system and overall well-being. Option A (5 to 10 g) is too low and may not provide sufficient fiber intake. Option B (10 to 15 g) is also below the recommended range. Option D (40 to 50 g) is too high and can lead to gastrointestinal discomfort and other complications if consumed in excess.
4. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?
- A. reducing cholesterol synthesis
- B. suppressing inflammation
- C. reducing blood clotting
- D. interfering with cholesterol and bile absorption
Correct answer: D
Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.
5. Which of the following is NOT a physiological role of proteins?
- A. Providing resistance to disease
- B. Regulating fluid balance
- C. Repairing tissue
- D. Serving as the primary source of energy
Correct answer: D
Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.
