Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

  • 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: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.

Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

  • 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 first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

Each statement is true of fat-soluble vitamins, except one. Which is the exception?

  • A. Fairly stable to heat, such as during cooking
  • B. Contain carbon
  • C. Stored in the pancreas
  • D. Absorbed in the intestine along with fats and lipids in food
Correct Answer: C

Rationale: Fat-soluble vitamins are not stored in the pancreas; they are stored in the liver and fatty tissues. Choice A is correct as fat-soluble vitamins are fairly stable to heat. Choice B is also correct as fat-soluble vitamins contain carbon. Choice D is correct as fat-soluble vitamins are absorbed in the intestine along with fats and lipids in food.

Scurvy is caused by a deficiency of which vitamin?

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

Rationale: Scurvy is caused by a deficiency of vitamin C, not vitamin E. The symptoms of scurvy include spontaneous gingival hemorrhaging, perifollicular petechiae, follicular hyperkeratosis, diarrhea, fatigue, depression, and cessation of bone growth. Vitamin A (Choice A) is important for vision and immune function, Vitamin D (Choice B) is essential for bone health, and Vitamin K (Choice D) is necessary for blood clotting. However, none of these vitamins are associated with scurvy.

Each statement is true of calcium within saliva, except one. Which is the exception?

  • A. Saliva is supersaturated with calcium.
  • B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
  • C. Calcium and phosphate in saliva provide a buffering action.
  • D. Calcium within saliva increases dental caries.
Correct Answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

Each is a physiologic role of vitamin D, except one. Which is the exception?

  • A. Hematopoiesis
  • B. Cardiac and neuromuscular function
  • C. Immune responses
  • D. Serum calcium regulation
Correct Answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.
