1. 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.

2. Which body organ is responsible for the metabolic processing of glucose?

• A. Large intestine.
• B. Gallbladder.
• C. Pancreas.
• D. Liver.

Correct answer: D

Rationale: The correct answer is the liver. The liver plays a central role in glucose homeostasis by metabolically processing glucose. The large intestine is primarily involved in absorbing water and electrolytes, not glucose. The gallbladder stores bile produced by the liver but is not directly involved in glucose metabolism. Although the pancreas produces insulin, a hormone that regulates blood sugar levels, the liver is mainly responsible for the metabolic processing of glucose.

3. How many amino acids are considered indispensable or essential?

• A. 9
• B. 10
• C. 12
• D. 14

Correct answer: A

Rationale: The correct answer is A: 9. Nine amino acids are considered essential or indispensable because they cannot be synthesized by the body and must be obtained through the diet. These amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices B, C, and D are incorrect as the number of essential amino acids is specifically 9, as they are crucial for various bodily functions.

4. Individuals with optimal nutritional status differ from those with marginal nutritional status in their:

• A. nutrient reserves.
• B. clinical signs.
• C. body weight.
• D. risk of mental illness.

Correct answer: A

Rationale: Individuals with optimal nutritional status differ from those with marginal nutritional status in their nutrient reserves. Optimal nutritional status implies having adequate nutrient reserves, which is lacking in marginal status. Clinical signs (choice B) may or may not be present in both groups and are not the differentiating factor between optimal and marginal statuses. Body weight (choice C) can vary for reasons other than nutritional status. The risk of mental illness (choice D) is not directly related to the comparison between optimal and marginal nutritional status.

5. 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.
