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. Patients with congestive heart failure need to restrict their intake of:
- A. fiber
- B. sodium
- C. cholesterol
- D. saturated fat
Correct answer: B
Rationale: Patients with congestive heart failure need to restrict their intake of sodium. This restriction is crucial to prevent fluid retention, which can exacerbate the condition. While fiber is generally beneficial for heart health, sodium restriction is more critical in this scenario. Cholesterol and saturated fat intake should also be monitored, but sodium restriction takes precedence due to its direct impact on fluid balance.
3. Which set of guidelines is intended to assess nutrient adequacy or plan intake of a population group, not individuals?
- A. RDA
- B. EAR
- C. DRA
- D. UL
Correct answer: B
Rationale: The Estimated Average Requirement (EAR) is the correct choice because it is specifically designed to assess the nutrient adequacy of population groups, not individuals. The Recommended Dietary Allowance (RDA) (choice A) is the average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy individuals in a particular life stage and gender group. The Dietary Reference Intake (DRI) (choice C) includes the EAR, RDA, Adequate Intake (AI), and UL, making it a broader set of nutrient reference values. The Tolerable Upper Intake Level (UL) (choice D) is the highest average daily nutrient intake level that is likely to pose no risk of adverse health effects to almost all individuals in the general population.
4. Each is a portion of the alimentary canal, except one. Which is the exception?
- A. Oral cavity
- B. Pharynx
- C. Larynx
- D. Esophagus
Correct answer: C
Rationale: The correct answer is C, Larynx. The larynx is part of the respiratory system, responsible for voice production and breathing. The alimentary canal is involved in the digestive process and includes structures like the oral cavity (mouth), pharynx, and esophagus. Choices A, B, and D are parts of the alimentary canal, where digestion occurs, making them incorrect answers.
5. The recommended daily fluid intake of patients maintained using hemodialysis is:
- A. 150 mL plus the volume of urinary output
- B. 500 mL plus the volume of urinary output
- C. 1000 mL plus the volume of urinary output
- D. 1500 mL plus the volume of urinary output
Correct answer: C
Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.
