ATI Nutrition Proctored Exam
1. Each of the following describes the physiologic roles of water, except one. Which is the exception?
- A. Acts as a solvent for chemical reactions.
- B. Maintains stability of body fluids.
- C. Enables transport of nutrients and excretion of waste.
- D. Regulates temperature by pooling as perspiration on skin.
Correct answer: D
Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.
2. Each of the following is a form of vitamin K, except one. Which is the exception?
- A. Phylloquinone
- B. Tocopherol
- C. Menaquinone
- D. Menadione
Correct answer: B
Rationale: Tocopherol, Choice B, is not a form of vitamin K; it is another name for vitamin E. Phylloquinone (Choice A), menaquinone (Choice C), and menadione (Choice D) are all forms of vitamin K. Phylloquinone is vitamin K1 found in green plants, menaquinone is vitamin K2 produced in the large intestine and found in animal tissues, and menadione is a synthetic form of vitamin K. Therefore, Choice B is the correct answer because it does not belong to the vitamin K group, unlike the other options.
3. Patients with this chronic nutrient deficiency may feel tired, weak, and irritable while being unable to pinpoint why. Hypertension, heart attack, stroke, kidney stones, and osteoporosis are associated with the chronic deficiency of which nutrient?
- A. Zinc
- B. Iron
- C. Sodium
- D. Potassium
Correct answer: D
Rationale: The correct answer is D: Potassium. Chronic potassium deficiency can lead to hypertension, heart attack, stroke, kidney stones, and osteoporosis. Patients experiencing this deficiency may feel tired, weak, and irritable without knowing the cause. Choice A (Zinc) is incorrect as zinc deficiency presents with different symptoms. Choice B (Iron) deficiency is associated with anemia symptoms, not the conditions listed. Choice C (Sodium) deficiency typically manifests as muscle cramps, weakness, and confusion, not the conditions described in the question.
4. How long can Vitamin A be stored in the liver for at least?
- A. 1 month.
- B. 6 months.
- C. 1 year.
- D. 18 months.
Correct answer: C
Rationale: Vitamin A can be stored in the liver to meet basic needs for at least 1 year. This storage capacity allows the body to have a reserve of Vitamin A to sustain its needs over an extended period. Choices A, B, and D are incorrect because they underestimate the storage capacity of Vitamin A in the liver, which can last longer than these durations.
5. 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.
