1. A mother asks about healthy snacks for her three children under 4 years old. All are wise choices the dental hygienist can recommend, except one. Which is the exception?

A. Low-fat milk or yogurt
B. Whole-grain cereals
C. Raw vegetable sticks
D. Nuts and seeds

Correct answer: D

Rationale: Nuts and seeds pose a choking hazard for children under 4 years old, making them an unsafe snack choice for young children. While low-fat milk or yogurt, whole-grain cereals, and raw vegetable sticks are healthy snack options suitable for children under 4 years old, nuts and seeds should be avoided due to the risk of choking, especially in young children who may not have fully developed chewing abilities.

2. Which nutrient is critical for wound healing and immune function?

A. Vitamin B12
B. Vitamin C
C. Vitamin D
D. Vitamin K

Correct answer: B

Rationale: Vitamin C is essential for collagen formation and immune function.

3. 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.

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.
