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 of the following sandwiches is high in saturated fatty acids?

• A. Tuna salad
• B. Grilled cheese
• C. Turkey and sprouts
• D. Peanut butter and jelly

Correct answer: B

Rationale: The correct answer is Grilled cheese because it is high in saturated fatty acids due to the dairy fat content in cheese. Tuna salad, turkey and sprouts, and peanut butter and jelly do not contain as high levels of saturated fatty acids as grilled cheese. Tuna salad typically contains mayonnaise which may contribute to some saturated fat content, but it is generally lower compared to the cheese in grilled cheese. Turkey and sprouts are leaner options, while peanut butter and jelly are higher in unsaturated fats rather than saturated fats.

3. Exchange Lists for Meal Planning was originally intended as a meal-planning tool for people who have:

• A. cancer.
• B. diabetes.
• C. hypertension.
• D. heart disease.

Correct answer: B

Rationale: The correct answer is B: diabetes. Exchange Lists for Meal Planning were originally created to assist individuals with diabetes in managing their diet by providing a structured approach to balanced food exchanges. This system helps individuals regulate their blood sugar levels and maintain overall health. Choices A, C, and D are incorrect because Exchange Lists for Meal Planning were not primarily developed for individuals with cancer, hypertension, or heart disease.

4. A vegetarian diet that includes dairy foods and eggs is known as:

• A. lactovegetarian.
• B. vegan.
• C. semi-vegetarian.
• D. ovolactovegetarian.

Correct answer: D

Rationale: The correct term for a vegetarian diet that includes both dairy foods and eggs is 'ovolactovegetarian.' This term specifically indicates the inclusion of eggs ('ovo') and dairy ('lacto') in the diet. Choice A, 'lactovegetarian,' is incorrect because it only includes dairy products without eggs. Choice B, 'vegan,' is incorrect as it excludes all animal products, including dairy and eggs. Choice C, 'semi-vegetarian,' is incorrect as it is a term used for individuals who occasionally eat meat, poultry, or fish but primarily follow a plant-based diet.

5. Sucrose consists of a combination of glucose and:

• A. maltose.
• B. fructose.
• C. galactose.
• D. lactose.

Correct answer: B

Rationale: The correct answer is B, fructose. Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose. Maltose (choice A) is composed of two glucose molecules, galactose (choice C) is a monosaccharide, and lactose (choice D) is composed of one molecule of glucose and one molecule of galactose. Therefore, fructose is the correct choice for the second component of sucrose.
