1. The professional primarily responsible for the application of nutrition science in clinical practice settings is the:
- A. nurse.
- B. physician.
- C. public health nutritionist.
- D. registered dietitian.
Correct answer: D
Rationale: The correct answer is D: registered dietitian. A registered dietitian is a healthcare professional with specialized training in nutrition and dietetics, making them primarily responsible for applying nutrition science in clinical practice settings. Nurses (choice A) and physicians (choice B) may have some knowledge of nutrition, but a registered dietitian has specific expertise in this area. Public health nutritionists (choice C) typically focus on community nutrition and public health programs, rather than clinical practice settings.
2. What is the basis of MyPlate food guidance?
- A. Percentage of calories from each macronutrient.
- B. Exchange Lists for Meal Planning.
- C. Appropriate amounts of food from each food group.
- D. Amounts of macronutrients and micronutrients.
Correct answer: C
Rationale: The correct answer is C: 'Appropriate amounts of food from each food group.' MyPlate food guidance focuses on portion sizes from different food groups to promote a balanced diet. Choices A, B, and D are incorrect because MyPlate emphasizes the consumption of a variety of foods from different food groups rather than focusing solely on macronutrient percentages, exchange lists, or specific nutrient amounts.
3. Most fat replacers are made from:
- A. proteins.
- B. carbohydrates.
- C. cholesterol.
- D. monoglycerides.
Correct answer: B
Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.
4. What is the interrelated network of nerves within the gastrointestinal wall that regulates its muscular action known as?
- 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. The intramural nerve plexus is the interrelated network of nerves within the gastrointestinal wall that regulates its muscular action. The gastric nerve plexus (choice A) specifically pertains to the network of nerves in the stomach, not the entire gastrointestinal wall. The biliary nerve plexus (choice B) is associated with nerve supply in the liver, gallbladder, and bile ducts, not the gastrointestinal wall. The intestinal nerve plexus (choice D) is a general term that may refer to various nerve networks within the intestines but does not specifically address the entire gastrointestinal wall.
5. Cholecystokinin (CCK) is produced in the:
- A. duodenum.
- B. stomach.
- C. pancreas.
- D. liver.
Correct answer: A
Rationale: Cholecystokinin (CCK) is produced in the duodenum, not the stomach, pancreas, or liver. It is released in response to the presence of food in the duodenum, where it plays a crucial role in regulating digestive processes by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Therefore, the correct answer is the duodenum (Choice A). Choices B, C, and D are incorrect because CCK is not produced in the stomach, pancreas, or liver.
