1. Which is most likely to initiate periodontal disease?

A. Nutrient deficiencies
B. Nutrient excesses
C. Nutrient imbalances
D. Plaque biofilm

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.

2. Water loss can occur from each, except one. Which is the exception?

A. Respiratory inflammation
B. Strenuous exercise
C. Diarrhea
D. Perspiration

Correct answer: D

Rationale: The correct answer is D, Perspiration. Water loss can occur through respiration inflammation, strenuous exercise, and diarrhea. Perspiration, also known as sweating, is a mechanism by which the body regulates temperature and eliminates some waste products, but it is not a cause of water loss. The body loses water through sweating, but this loss is mainly for cooling purposes, and it is not a primary mechanism for water loss like respiration, exercise, or diarrhea.

3. A client who is breastfeeding is being taught diet modification by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

A. I should drink an 8-ounce glass of water each time my baby nurses.
B. I should take a 1500-milligram iron supplement daily.
C. I can eat a 2500-calorie daily diet to lose 1 lb per week.
D. I can eat ounces of swordfish daily.

Correct answer: A

Rationale: The correct answer is A because drinking an 8-ounce glass of water each time the baby nurses helps maintain hydration and support milk production. Choice B is incorrect as the need for iron supplementation should be discussed with a healthcare provider. Choice C is incorrect as a 2500-calorie diet is not typically recommended for weight loss during breastfeeding. Choice D is incorrect as consuming high levels of swordfish is not advisable due to its mercury content, which can be harmful to the baby.

4. Which set of guidelines is intended to assess nutrient adequacy or plan intakes of population groups, not individuals?

A. Old Recommended Dietary Allowances (RDA)
B. Estimated Average Requirement (EAR)
C. New Recommended Dietary Allowances (RDA)
D. Tolerable Upper Intake Level (UL)

Correct answer: B

Rationale: The Estimated Average Requirement (EAR) is specifically designed to assess nutrient adequacy or plan intakes for population groups, not for individuals. The Old and New Recommended Dietary Allowances (RDA) are meant for individuals, not groups, as they provide guidelines for specific nutrient intake levels for healthy individuals. The Tolerable Upper Intake Level (UL) is used to set the highest level of nutrient intake that is likely to pose no risk of adverse health effects for most individuals in a group, which is different from assessing nutrient adequacy for groups.

5. A nurse is planning teaching for the parents of a toddler who follows a vegetarian diet. The nurse should plan to include which of the following foods as the best source of dietary protein for the child?

A. Soy milk
B. Peanut butter
C. Dried beans
D. Whole grains

Correct answer: C

Rationale: Dried beans are the best source of dietary protein for a toddler following a vegetarian diet. They are rich in protein and other essential nutrients. Soy milk, while a good source of protein, may not provide as much protein density as dried beans. Peanut butter is a good source of protein but may not be as protein-dense as dried beans. Whole grains are not as high in protein content compared to dried beans, making them a less optimal choice for meeting the toddler's protein needs.
