1. A person with lactose intolerance should be most careful to limit their intake of:

• A. milk
• B. yogurt
• C. cheese
• D. corn syrup

Correct answer: A

Rationale: Individuals with lactose intolerance lack the enzyme lactase needed to break down lactose, the sugar in dairy products. Milk contains a high amount of lactose, making it crucial for those with lactose intolerance to limit their intake. Yogurt and cheese, on the other hand, have lower lactose content due to the fermentation process which reduces lactose levels, making them better tolerated by many with lactose intolerance. Corn syrup, although high in sugar, does not contain lactose and is unrelated to lactose intolerance. Therefore, the correct answer is 'milk' as it is a significant source of lactose, which can trigger symptoms in individuals with lactose intolerance.

2. Exchange Lists for Meal Planning group foods that are equivalent in their:

• A. weight.
• B. serving size.
• C. micronutrient content.
• D. macronutrient content.

Correct answer: D

Rationale: The Exchange Lists for Meal Planning categorize foods based on their macronutrient content, such as carbohydrate, protein, and fat. These lists help individuals make food choices while ensuring similar amounts of macronutrients are consumed. Therefore, the correct answer is D. Choices A, B, and C are incorrect because Exchange Lists focus on macronutrient content, not weight, serving size, or micronutrient content.

3. The type of protein-energy malnutrition that results in edema, hypoalbuminemia, skin lesions, and fatty liver is:

• A. cachexia.
• B. marasmus.
• C. kwashiorkor.
• D. sarcopenia.

Correct answer: C

Rationale: The correct answer is C, kwashiorkor. Kwashiorkor is a type of protein-energy malnutrition characterized by edema, hypoalbuminemia, skin lesions, and fatty liver. Edema is a key feature of kwashiorkor due to hypoalbuminemia, which leads to decreased oncotic pressure. Marasmus (choice B) is a form of severe malnutrition characterized by energy deficiency without significant protein deficiency, resulting in severe wasting. Cachexia (choice A) is a syndrome characterized by weight loss, muscle atrophy, fatigue, weakness, and loss of appetite in someone who is not actively trying to lose weight. Sarcopenia (choice D) is the age-related loss of muscle mass and function.

4. Why are bacteria found in the colon important?

• A. synthesize important vitamins.
• B. complete the process of absorption.
• C. synthesize some minerals.
• D. finish the process of digestion.

Correct answer: A

Rationale: Bacteria found in the colon are important because they synthesize important vitamins, such as vitamin K. This aids in the body's overall health and functioning. Choice B is incorrect because absorption primarily occurs in the small intestine, not the colon. Choice C is incorrect as the synthesis of minerals is not a primary function of colon bacteria. Choice D is incorrect as the digestion process mainly occurs in the stomach and small intestine.

5. Where are sugar alcohols most likely to be found?

• A. Fermented foods.
• B. Low-calorie foods.
• C. Fruits and vegetables.
• D. Fiber supplements.

Correct answer: B

Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.
