Nutrition Final Exam Quizlet
1. What does a positive correlation between two variables indicate?
- A. One variable causes the other.
- B. Both variables move in the same direction.
- C. Both variables move in opposite directions.
- D. There is no relationship between the variables.
Correct answer: B
Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.
2. How should hydration status in a child with fever and vomiting be assessed?
- A. Monitor skin turgor and mucous membranes
- B. Measure blood glucose levels
- C. Check for signs of jaundice
- D. Assess respiratory rate
Correct answer: A
Rationale: To assess hydration status in a child with fever and vomiting, monitoring skin turgor and mucous membranes is essential. Skin turgor refers to the skin's ability to change shape and return to normal; poor skin turgor can indicate dehydration. Mucous membranes, such as the mouth and eyes, can also provide valuable information about hydration levels. Measuring blood glucose levels (Choice B) is not directly related to assessing hydration status. Checking for signs of jaundice (Choice C) is important for liver-related issues, not hydration assessment. Assessing respiratory rate (Choice D) is crucial for evaluating respiratory function, not hydration status.
3. An essential nutrient is one that ___
- A. must be made in large quantities by the body
- B. can only be synthesized by the body
- C. cannot be made in sufficient quantities by the body
- D. is used to synthesize other compounds in the body
Correct answer: C
Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.
4. What is a common early sign of type 1 diabetes in children?
- A. Excessive thirst and frequent urination
- B. Severe abdominal pain
- C. Frequent headaches
- D. Sudden weight gain
Correct answer: A
Rationale: Excessive thirst and frequent urination are common early signs of type 1 diabetes in children. These symptoms occur due to high blood glucose levels, leading to increased thirst and urination. Severe abdominal pain (choice B) is not typically associated with type 1 diabetes. Although frequent headaches (choice C) can occur in some cases, they are not as specific to type 1 diabetes as excessive thirst and frequent urination. Sudden weight gain (choice D) is not a common early sign of type 1 diabetes; in fact, unexplained weight loss is more characteristic of the condition.
5. How should a caregiver manage a child with a known allergy to peanuts?
- A. Avoid all peanut-containing products
- B. Encourage regular exposure to peanuts
- C. Administer antihistamines daily
- D. Recommend peanut-containing supplements
Correct answer: A
Rationale: Avoiding peanut-containing products is crucial for managing a peanut allergy and preventing allergic reactions. Choice B suggesting regular exposure to peanuts can be harmful and trigger severe allergic reactions in a child with a peanut allergy. Regular exposure can increase the risk of anaphylaxis. Choice C of administering antihistamines daily is not a primary prevention strategy and should not be the first-line approach for managing a peanut allergy. Antihistamines only treat symptoms and do not prevent the allergic reaction. Choice D of recommending peanut-containing supplements can also lead to severe allergic reactions and is not recommended for a child with a known peanut allergy. It is essential to eliminate all sources of peanuts to prevent accidental exposure and potential life-threatening reactions.
