1. Which of the following is a good food source of iodine?

• A. Seafood
• B. Lettuce
• C. Broccoli
• D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

2. Among people who are ill, significant weight loss may be masked by?

• A. dehydration
• B. a large tumor
• C. drug therapy
• D. fluid retention

Correct answer: D

Rationale: Fluid retention can mask weight loss in ill individuals as the retained fluid adds to body weight, making it difficult to detect true fat or muscle loss. Dehydration (Choice A) would actually lead to weight loss rather than masking it. While a large tumor (Choice B) could contribute to weight loss, it would not mask the weight loss itself. Drug therapy (Choice C) may cause side effects, including weight changes, but it is unlikely to mask significant weight loss in the same way that fluid retention does.

3. For patients with hypertension, which dietary change is most recommended?

• A. Increase salt intake
• B. Reduce fiber intake
• C. Increase potassium intake
• D. Reduce sugar intake

Correct answer: C

Rationale: Increasing potassium intake can help reduce blood pressure in hypertensive patients.

4. Fatty acids may differ from one another:

• A. in chain length
• B. in degree of saturation
• C. in number of calories
• D.

Correct answer: D

Rationale: Fatty acids vary in chain length and degree of saturation, affecting their physical properties and health effects.

5. Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.

• 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: D

Rationale: The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.
