1. In addition to protein, which nutrients contribute to the building and repair of tissue?
- A. Vitamins
- B. Carbohydrates
- C. Fats
- D. Enzymes
Correct answer: A
Rationale: The correct answer is A: Vitamins. Vitamins play a crucial role in tissue building and repair along with protein. Carbohydrates (choice B) are primarily a source of energy and not directly involved in tissue building. Fats (choice C) are important for energy storage and insulation but are not the main contributors to tissue building. Enzymes (choice D) are biological catalysts and do not directly contribute to tissue building and repair.
2. Which of the following provides the best source of nutrients?
- A. specific food combinations.
- B. a variety of foods.
- C. individual foods.
- D. a variety of food supplements.
Correct answer: B
Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.
3. Which of the following plasma proteins helps maintain fluid balance?
- A. Albumin
- B. Fibrinogen
- C. Hemoglobin
- D. Collagen
Correct answer: A
Rationale: Albumin is the correct answer. It is a plasma protein that helps maintain osmotic pressure, thereby playing a vital role in regulating fluid balance in the body. Fibrinogen is involved in blood clotting, not fluid balance. Hemoglobin is responsible for oxygen transport in red blood cells, not fluid balance. Collagen is a structural protein found in connective tissues, not directly involved in fluid balance.
4. Carbohydrates are composed of a combination of carbon, hydrogen, and which other element?
- A. oxygen.
- B. nitrogen.
- C. water.
- D. glucose.
Correct answer: A
Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.
5. What is the factor most likely to stimulate digestive secretions?
- A. Smelling or seeing food
- B. Grocery shopping
- C. Fasting
- D. Exercise
Correct answer: A
Rationale: The correct answer is A: Smelling or seeing food. When an individual smells or sees food, it can trigger the body to start producing digestive secretions in anticipation of food consumption. This physiological response helps prepare the digestive system for the incoming meal. Choices B, C, and D are incorrect because grocery shopping, fasting, and exercise do not directly stimulate digestive secretions in the same way that the sight or smell of food does.
