1. What primarily determines the Dietary Reference Intake (DRI) for protein?
- A. Intake of fatty acids
- B. Gender
- C. Height
- D. Body weight
Correct answer: D
Rationale: The Dietary Reference Intake (DRI) for protein is primarily determined by an individual's body weight. This is because the body's protein requirement is proportionate to its size, which is generally reflected in the body weight. Therefore, choice D is correct. Choices A, B, and C are incorrect: While factors such as fatty acid intake, gender, and height can influence an individual's overall nutritional needs, they do not directly determine the DRI for protein.
2. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?
- A. Zinc
- B. Iron
- C. Sodium
- D. Potassium
Correct answer: B
Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.
3. Is it correct that eliminating sucrose from the diet leads to a significant reduction in dental caries, and that the best advice is to consume sugar in moderation and limit the frequency of sugar exposure?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: D
Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.
4. A client with stomatitis is receiving teaching from a nurse. Which of the following client statements indicates a need for further teaching?
- A. “I will drink liquids through a straw.”
- B. “I will season foods with dried spices before cooking.”
- C. “I will rinse my mouth with baking soda and water frequently.”
- D. “I will eat frozen bananas as a snack.”
Correct answer: “I will rinse my mouth with baking soda and water frequently.”
Rationale: The correct answer is, “I will rinse my mouth with baking soda and water frequently.” Stomatitis is an inflammation of the mucous lining in the mouth, and rinsing with baking soda and water can be too abrasive and further irritate the condition. Choices A, B, and D are appropriate self-care measures for a client with stomatitis and do not indicate a need for further teaching.
5. 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.
