Nursing Elites

1. Fructose is the sugar found in:

• A. bread.
• B. gelatin desserts.
• C. sugar-coated cereals.
• D. honey and fruit.

Correct answer: D

Rationale: Fructose is a sugar naturally found in honey and fruit. While bread contains carbohydrates, it does not primarily consist of fructose. Gelatin desserts are more likely to contain added sugars like sucrose rather than fructose. Sugar-coated cereals typically contain sucrose or other added sugars, not just fructose. Therefore, the correct answer is honey and fruit as they naturally contain fructose.

2. The end products of digestion of macronutrients include fatty acids, amino acids, and:

• A. monosaccharides.
• B. polysaccharides.
• C. enzymes.
• D. cholesterol.

Correct answer: A

Rationale: The correct answer is A: monosaccharides. When macronutrients like carbohydrates are digested, they are broken down into simpler forms. Carbohydrates are broken down into monosaccharides, proteins into amino acids, and fats into fatty acids. Therefore, the end products of carbohydrate digestion are monosaccharides. Choices B, C, and D are incorrect because polysaccharides are larger carbohydrate molecules, enzymes are not the end products of digestion but rather aid in the process, and cholesterol is not a direct end product of macronutrient digestion.

3. How does a nursing infant receive antibodies from its mother?

• A. Through anabolism and catabolism.
• B. Through the absorption of antibodies.
• C. Through the absorption of amino acids and synthesis of antibodies.
• D. Through genetic inheritance.

Correct answer: B

Rationale: A nursing infant receives antibodies from its mother through the absorption of antibodies present in breast milk. Choice A is incorrect as anabolism and catabolism refer to metabolic processes, not the transfer of antibodies. Choice C is incorrect as the infant does not need to synthesize antibodies but directly receives them. Choice D is incorrect because while genetic inheritance plays a role in the immune system, in this case, the direct transfer of antibodies occurs through breast milk.

4. What is the term for the action of biting, chewing, and breaking up ingested food into smaller particles?

• A. Peristalsis.
• B. Segmentation.
• C. Metabolism.
• D. Mastication.

Correct answer: D

Rationale: The correct answer is D, 'Mastication.' Mastication is the mechanical process of chewing that breaks down food into smaller particles. Peristalsis (choice A) is the involuntary constriction and relaxation of muscles in the gastrointestinal tract that moves food along. Segmentation (choice B) is the mixing movement of the digestive system that helps to break down food and mix it with digestive juices. Metabolism (choice C) refers to the chemical processes that occur within a living organism to maintain life.

5. 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.
