The nutrient facts panel was established by the USDA and the FDA to improve health and well-being by enhancing nutritional knowledge. Nutrient content claims describe a relationship between a food or food component and reduced risk of a disease or health-related condition.

  • A. Both statements are true.
  • B. Both statements are false.
  • C. The first statement is true; the second is false.
  • D. The first statement is false; the second is true.
Correct Answer: C

Rationale: The correct answer is C. The first statement is true as the nutrient facts panel was indeed established by the USDA and the FDA to improve health and well-being by enhancing nutritional knowledge. However, the second statement is false. Nutrient content claims actually refer to the amount of a nutrient in a food, not to the relationship between a food and disease risk. Therefore, the second statement is incorrect, making choice C the correct option. Choice A is incorrect because the second statement is false. Choice B is incorrect as the first statement is true. Choice D is incorrect because the second statement is false.

Choice B is incorrect because both statements are true, as supported by medical literature. Choice C is incorrect because the second statement is also true. Choice D is incorrect because the first statement is true.

  • C. The first statement is true; the second is false.
  • D. The first statement is false; the second is true.

The second statement is true because making a dietary change to eliminate or increase the intake of a specific food or nutrient often leads to alterations in the intake of other nutrients. Choice A is incorrect because the first statement is false. Choice B is incorrect because the second statement is true.

The principal cation in plasma and interstitial fluid is:

  • A. Sodium
  • B. Potassium
  • C. Calcium
  • D. Magnesium
Correct Answer: A

Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.

Which physiologic role does vitamin C play in the body?

  • A. Transcribing DNA to RNA
  • B. Absorption and regulation of calcium
  • C. Protects integrity of cellular membranes
  • D. Catalyst for synthesis of blood-clotting factors
Correct Answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.

Each of the following is a fat-soluble vitamin except for one. Which is the exception?

  • A. Vitamin A
  • B. Vitamin C
  • C. Vitamin D
  • D. Vitamin K
Correct Answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.
