1. What is a common complication of uncontrolled type 1 diabetes in children?

• A. Hyperactivity
• B. Ketoacidosis
• C. Hypertension
• D. Hypoglycemia

Correct answer: B

Rationale: Ketoacidosis is a prevalent complication of uncontrolled type 1 diabetes in children. It is a serious condition characterized by high levels of ketones in the blood, leading to acidosis. Prompt medical attention is necessary to manage this potentially life-threatening condition. Choice A, hyperactivity, is not a typical complication of uncontrolled type 1 diabetes. Choice C, hypertension, is not a direct complication of type 1 diabetes in children. Choice D, hypoglycemia, is more commonly associated with low blood sugar levels, which can occur due to excessive insulin administration or inadequate food intake in diabetic individuals, rather than uncontrolled type 1 diabetes.

2. What is the term for the study of how diet affects gene expression?

• A. Epigenetics
• B. Nutrigenomics
• C. Genomics
• D. Genetics

Correct answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.

3. Which statement is true of minerals in their role as nutrients?

• A. They are organic compounds.
• B. They yield 4 kilocalories per gram.
• C. Some become dissolved in body fluids.
• D. Some are destroyed during cooking.

Correct answer: C

Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.

4. What is one characteristic that differentiates vitamins from minerals?

• A. Vitamins are organic compounds.
• B. Vitamins provide energy.
• C. Vitamins are considered micronutrients.
• D. Vitamins are essential in small amounts.

Correct answer: A

Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.

5. Approximately how many grams does a normal half-cup vegetable portion weigh?

• A. 5 grams
• B. 50 grams
• C. 100 grams
• D. 150 grams

Correct answer: C

Rationale: A normal half-cup vegetable portion usually weighs around 100 grams. This weight is a standard measurement for a half-cup serving of vegetables, making choice C the correct answer. Choices A, B, and D are incorrect as they do not align with the typical weight of a half-cup vegetable portion.
