1. Which is NOT a classification of carbohydrate?

• A. Monosaccharides
• B. Disaccharides
• C. Polysaccharides
• D. Triglycerides

Correct answer: D

Rationale: The correct answer is D, Triglycerides. Triglycerides are a type of fat, not a carbohydrate. Monosaccharides, disaccharides, and polysaccharides are all classifications of carbohydrates based on the number of sugar units they contain. Monosaccharides are the simplest form with one sugar unit, disaccharides contain two sugar units, and polysaccharides have multiple sugar units linked together.

2. A nurse is teaching a client about complete and incomplete proteins. Which of the following foods should the nurse include in the teaching as an incomplete protein?

• A. 4 oz chickpeas
• B. 2 poached eggs
• C. 2 oz cheddar cheese
• D. 4 oz salmon fillet

Correct answer: A

Rationale: The correct answer is A: 4 oz chickpeas. Chickpeas are considered an incomplete protein because they lack one or more essential amino acids required by the body. Incomplete proteins do not provide all essential amino acids in sufficient quantities. Choice B, 2 poached eggs, is a complete protein source because eggs contain all essential amino acids. Choice C, 2 oz cheddar cheese, is also a complete protein as it contains all essential amino acids. Choice D, 4 oz salmon fillet, is another complete protein source as fish typically provide all essential amino acids needed by the body.

3. Which client is most likely to need regular injections of vitamin B12?

• A. The client with malabsorption syndrome.
• B. The client following a vegan eating pattern.
• C. The client whose stomach does not produce intrinsic factors.
• D. The client with alcoholism.

Correct answer: C

Rationale: The correct answer is C. The client whose stomach does not produce intrinsic factors is most likely to need regular injections of vitamin B12. Intrinsic factor is essential for the absorption of vitamin B12. Without intrinsic factor, the client cannot absorb vitamin B12 from food, necessitating the need for regular injections. Choices A, B, and D do not directly impact the production of intrinsic factors in the stomach, so they are less likely to result in the need for vitamin B12 injections.

4. Bacterial growth and plaque formation are enhanced by a diet with frequent intake of retentive carbohydrates. Gingivitis is an irreversible change in the interdental papillary tissues.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: C

Rationale: The correct answer is C. The first statement is true; retentive carbohydrates promote bacterial growth and plaque formation. However, the second statement is false; gingivitis is not irreversible and is often reversible with proper care. Gingivitis is the inflammation of the gums due to plaque buildup and poor oral hygiene. With good oral hygiene practices and professional dental care, gingivitis can be reversed. The other choices are incorrect because gingivitis is not irreversible, making statement two false.

5. What is the first step in the scientific method?

• A. Conduct an experiment
• B. Make an observation and ask a question
• C. Formulate a hypothesis
• D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.
