1. Dietary guidelines are most useful for:
- A. limiting portion sizes.
- B. designing a personal food plan.
- C. making smart food choices.
- D. avoiding excessive nutrient intakes.
Correct answer: C
Rationale: Dietary guidelines are designed to assist individuals in making smart food choices by providing recommendations on what to eat to maintain good health. While portion sizes may be a part of these guidelines, they are not the primary focus. Designing a personal food plan involves individual preferences and needs, which may go beyond general guidelines. Avoiding excessive nutrient intakes is important, but dietary guidelines aim to provide balanced recommendations rather than just focusing on avoiding excess.
2. Which of the following foods is high in indispensable amino acids?
- A. Lentils
- B. Tofu
- C. Peanuts
- D. Eggs
Correct answer: D
Rationale: The correct answer is D, eggs. Eggs are considered a high-quality protein source as they are rich in indispensable amino acids. Lentils, tofu, and peanuts also contain protein but are not as high in indispensable amino acids as eggs, making them less complete protein sources.
3. What are the major sources of energy for the body?
- A. Proteins and fats.
- B. Carbohydrates and fats.
- C. Proteins and carbohydrates.
- D. Vitamins and minerals.
Correct answer: B
Rationale: The correct answer is B: Carbohydrates and fats. Carbohydrates are the body's primary and most efficient source of energy, providing fuel for daily activities. Fats are also a significant energy source, especially during times of prolonged or intense exercise. Proteins are primarily used for building and repairing tissues, not as a major energy source. Vitamins and minerals are essential for various bodily functions but do not serve as direct sources of energy.
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. The type of protein-energy malnutrition (PEM) that develops when the diet lacks protein is called:
- A. kwashiorkor.
- B. marasmus.
- C. anemia.
- D. beriberi.
Correct answer: A
Rationale: The correct answer is A: kwashiorkor. Kwashiorkor is a form of protein-energy malnutrition that arises due to a protein-deficient diet. This condition leads to symptoms such as edema, skin lesions, and fatty liver. Choice B, marasmus, is a form of PEM caused by overall malnutrition (protein and calorie deficiency), resulting in severe wasting and muscle loss. Choice C, anemia, is a condition characterized by a deficiency of red blood cells or hemoglobin, not specifically related to protein deficiency. Choice D, beriberi, is a disease caused by thiamine (Vitamin B1) deficiency, not a form of PEM related to protein deficiency.
