1. 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.
2. Which of the following nutrients provide energy?
- A. Carbohydrates
- B. Fats
- C. Protein
- D. Water
Correct answer: A, B, and C
Rationale: Carbohydrates, fats, and proteins are the three macronutrients that provide energy (calories) to the body. Carbohydrates are the body's primary source of energy, fats act as a secondary source when carbohydrate energy is exhausted, and proteins are used for energy when carbohydrate and fat sources are low. Choice D, Water, is essential for the body's functions, but it does not provide energy.
3. Which nursing diagnosis has nutritional implications?
- A. impaired dentition
- B. disruption of gas exchange
- C. self-esteem disturbance
- D. sleep pattern disturbance
Correct answer: A
Rationale: Impaired dentition affects a patient's ability to chew and consume a variety of foods, leading to potential nutritional deficiencies and malnutrition.
4. To follow a healthy diet, a person should be sure that:
- A. 20-35% of the total carbs eaten should be made up of fiber
- B. 45-65% of the total carbs eaten should be made up of fiber
- C. 45-65% of the total fiber eaten should be made up of soluble fiber
- D. 45-65% of the total calories eaten should be made up of carbs
Correct answer: D
Rationale: The Acceptable Macronutrient Distribution Range (AMDR) suggests that 45-65% of total daily calories should come from carbohydrates.
5. When is infertility said to exist?
- A. When a woman has no uterus
- B. When a woman has no children
- C. When a couple has been trying to conceive for 1 year without success
- D. When a couple has desired a child for 6 months
Correct answer: C: When a couple has been trying to conceive for 1 year without success
Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.
