1. Exchange Lists for Meal Planning was devised by the American Dietetic Association in collaboration with which organization?

• A. the American Cancer Society
• B. the American Diabetes Association
• C. the American Heart Association
• D. the Culinary Institute of America

Correct answer: B

Rationale: The correct answer is B: the American Diabetes Association. The American Dietetic Association collaborated with the American Diabetes Association to devise the Exchange Lists for Meal Planning. This collaboration aimed to assist individuals, especially those with diabetes, in planning balanced meals. Choices A, C, and D are incorrect as they were not involved in the development of the Exchange Lists.

2. Where is Vitamin B12 found?

• A. Whole grains.
• B. Nuts.
• C. Meats.
• D. Legumes.

Correct answer: C

Rationale: Vitamin B12 is primarily found in animal-derived foods like meats. Choices A, B, and D are incorrect as whole grains, nuts, and legumes do not naturally contain significant amounts of Vitamin B12. Therefore, the correct answer is 'C: Meats.'

3. What is the main body storage form of carbohydrates?

• A. Glycogen.
• B. Starch.
• C. Fat.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A: Glycogen. Glycogen is the stored form of carbohydrates in the body, primarily found in the liver and muscles. Starch (choice B) is a carbohydrate storage molecule in plants, not in the human body. Fat (choice C) is a different macronutrient and not the main storage form of carbohydrates. Glucose (choice D) is a simple sugar that serves as an energy source, not the main storage form of carbohydrates.

4. Regurgitation or reflux of acidic stomach contents back into the esophagus is known as:

• A. hiatal hernia.
• B. diverticulitis.
• C. gastroenteritis.
• D. gastroesophageal reflux disease.

Correct answer: D

Rationale: The correct answer is D: gastroesophageal reflux disease (GERD). GERD occurs when stomach acid flows back into the esophagus, causing symptoms like heartburn and regurgitation. Choice A, hiatal hernia, is a condition where part of the stomach pushes up into the chest through an opening in the diaphragm. Choice B, diverticulitis, is inflammation or infection of small pouches that can form in the lining of the digestive system. Choice C, gastroenteritis, is inflammation of the stomach and intestines typically caused by a viral or bacterial infection. Therefore, only choice D accurately describes the regurgitation or reflux of acidic stomach contents back into the esophagus.

5. What are the rhythmic contractions that propel food through the intestinal tract called?

• A. Segmentation
• B. Peristalsis
• C. Cardiospasm
• D. Pendular movements

Correct answer: B

Rationale: Peristalsis is the correct answer because it refers to the rhythmic contractions that propel food through the intestinal tract by pushing it along the digestive system. Segmentation, on the other hand, refers to the mixing movements in the intestines rather than the forward movement of food. Cardiospasm is a condition characterized by difficulty swallowing due to the inability of the esophagus to relax, and pendular movements are a type of motility found in the small intestine but do not specifically refer to the propulsion of food.
