1. Which of the following foods is the best source of omega-3 fatty acids?

• A. Salmon
• B. Chicken
• C. Spinach
• D. Eggs

Correct answer: A

Rationale: Salmon is the correct answer as it is a rich source of omega-3 fatty acids, specifically EPA and DHA, which are known to be beneficial for heart health. Chicken, spinach, and eggs do not contain significant levels of omega-3 fatty acids compared to salmon. While eggs do contain some omega-3s, the amount is considerably lower than what is found in fatty fish like salmon.

2. An essential nutrient must:

• A. be eaten every day
• B. be obtained by the diet
• C. be water soluble
• D. be eaten at every meal

Correct answer: B

Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.

3. How would protein deficiency likely affect dental tissues?

• A. Decreased resistance to dental caries
• B. Increased tooth size
• C. Delayed tooth development
• D. Increased enamel mineralization

Correct answer: C

Rationale: Protein deficiency can lead to delayed tooth development as the body may not have enough resources to form teeth properly. This delay can make the teeth more susceptible to dental issues due to incomplete formation. Choices A, B, and D are incorrect. Decreased resistance to dental caries is more related to factors like poor oral hygiene and sugary diets, increased tooth size is not a common effect of protein deficiency on dental tissues, and increased enamel mineralization is not typically associated with protein deficiency.

4. Which of the following provides the least amount of potassium?

• A. broccoli
• B. potatoes
• C. bananas
• D. cheese

Correct answer: D

Rationale: Cheese provides less potassium compared to broccoli, potatoes, and bananas, which are all rich in this essential mineral.

5. A client who is in her second trimester of pregnancy should increase her caloric intake by how many calories during this trimester?

• A. 110 cal/day
• B. 225 cal/day
• C. 340 cal/day
• D. 450 cal/day

Correct answer: C

Rationale: During the second trimester of pregnancy, it is recommended that a client increases their caloric intake by around 340 calories per day to support the growing needs of both the mother and the developing fetus. This additional intake helps ensure the proper nutrition and energy levels required during this crucial stage of pregnancy. Option A (110 cal/day) is too low to meet the increased demands. Option B (225 cal/day) is also below the recommended amount. Option D (450 cal/day) is higher than necessary and could lead to excessive weight gain, which is not ideal during pregnancy.
