1. The percentage of the total daily caloric intake for healthy persons that should be supplied by carbohydrate is:

• A. 10% to 35%.
• B. 20% to 35%.
• C. 40% to 55%.
• D. 45% to 65%.

Correct answer: D

Rationale: The correct answer is D: 45% to 65%. Carbohydrates should contribute between 45% to 65% of the total daily caloric intake for healthy individuals to maintain a balanced diet. Choices A, B, and C are incorrect because they suggest lower ranges, which may not provide sufficient energy from carbohydrates for overall health and well-being.

2. Which tissue has the highest rate of protein turnover?

• A. Skin
• B. Intestinal mucosa
• C. Muscle
• D. Adipose tissue

Correct answer: B

Rationale: The correct answer is B: Intestinal mucosa. The intestinal mucosa has the highest rate of protein turnover due to its rapid cell renewal. The skin, muscle, and adipose tissue do not exhibit protein turnover rates as high as the intestinal mucosa. Skin cells turnover relatively slower compared to the rapid renewal of intestinal mucosa cells. Muscles have a moderate rate of protein turnover, while adipose tissue has a lower turnover rate compared to the other tissues mentioned.

3. 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.

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. The interrelated network of nerves within the gastrointestinal wall that regulates its muscular action is known as the:

• A. gastric nerve plexus.
• B. biliary nerve plexus.
• C. intramural nerve plexus.
• D. intestinal nerve plexus.

Correct answer: C

Rationale: The correct answer is C - intramural nerve plexus. This network of nerves regulates the muscular movements within the gastrointestinal wall. The gastric nerve plexus (choice A) specifically relates to the stomach, not the entire gastrointestinal tract. The biliary nerve plexus (choice B) is associated with the bile ducts and gallbladder, not the regulation of muscular action. The intestinal nerve plexus (choice D) is a general term that doesn't specifically refer to the network of nerves within the gastrointestinal wall.
