Question 1 of 5
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?
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.

Question 2 of 5
Each is a physiologic role of vitamin D, except one. Which is the exception?
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.
Question 3 of 5
Which vitamin acts most like a hormone?
Correct Answer: C
Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels.

Choice B (Vitamin
B) is a complex of different vitamins that play various roles in the body.

Question 4 of 5
Increasing the variety of foods often prevents nutrient excesses and toxicities. A dietary change to eliminate or increase intake of one specific food or nutrient usually alters the intake of other nutrients.
Correct Answer: D
Rationale: The first statement is false because increasing the variety of foods actually helps prevent nutrient excesses and toxicities. 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.
Choice C is incorrect because the first statement is false, even though the second statement is true.
Question 5 of 5
Inadequate intake of vitamin A occurs in lower socioeconomic groups due to a lack of resources to purchase and consume vegetables and fruits.
Correct Answer: A
Rationale: Both the statement and the reason are correct and related. Inadequate intake of vitamin A in lower socioeconomic groups is due to a lack of resources to purchase and consume vegetables and fruits. This is supported by the fact that the average intake in the United States meets the Recommended Dietary Allowance (RD
A) for vitamin A intake, except in lower socioeconomic groups. These individuals often lack the financial means to buy, prepare, and eat a variety of fruits and vegetables, leading to deficiencies. It's important to note that because vitamin A can be stored in the liver, most adults have sufficient quantities to maintain health.
Choices B, C, and D are incorrect because the statement and reason are both accurate and logically connected, as the lack of resources directly impacts the ability to obtain necessary sources of vitamin A.
