1. Which type of fatty acid has carbon atoms connected by two or more double bonds?

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

2. 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.

3. What is a common symptom of vitamin D deficiency?

Correct answer: C

Rationale: The correct answer is C: Bone pain. Vitamin D deficiency often leads to bone pain and weakness as it plays a crucial role in maintaining bone health by aiding in the absorption of calcium. Hair loss (choice A) is not a common symptom of vitamin D deficiency. Night blindness (choice B) is typically associated with vitamin A deficiency, not vitamin D deficiency. Rashes (choice D) are not a common symptom of vitamin D deficiency.

4. Which systolic blood pressure measurement is classified as prehypertension?

Correct answer: B

Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.

5. For a client with metabolic syndrome, which dietary change is most beneficial?

Correct answer: B

Rationale: Decreasing trans fats helps manage metabolic syndrome by improving lipid profiles.
