1. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

2. What is the procedure called when direct observations are used to generate an estimate of a client's current food intake?

• A. Food diary
• B. 24-hour recall
• C. Kilocalorie count
• D. Nutrient surveillance record

Correct answer: C

Rationale: A kilocalorie count is the correct answer as it involves directly observing a client's food intake, which is often used in hospitals to accurately assess nutritional intake and ensure it meets dietary requirements. A food diary (Choice A) is typically self-reported by the client and not directly observed. A 24-hour recall (Choice B) is also usually self-reported and relies on a client's memory of the past 24 hours, which can be unreliable. A nutrient surveillance record (Choice D) is a broader term for tracking nutrient intake in a population and is not specific to the direct observation of an individual's food intake.

3. A client is being educated by a nurse on snacks suitable for a low-fat, low-sodium, and low-cholesterol diet. Which of the following food choices by the client indicates the need for further teaching?

• A. A slice of cheese
• B. A jam sandwich
• C. A cup of plain popcorn
• D. A small container of applesauce

Correct answer: A

Rationale: The correct answer is A: A slice of cheese. Cheese is high in fat, sodium, and cholesterol, making it unsuitable for a low-fat, low-sodium, and low-cholesterol diet. Choices B, C, and D are more appropriate for such a diet. B: A jam sandwich can be low in fat, sodium, and cholesterol if made with whole grain bread and a low-sugar jam. C: A cup of plain popcorn is a good choice as it is low in fat and can be made without added salt. D: A small container of applesauce is also a suitable option for a low-fat, low-sodium, and low-cholesterol diet.

4. Which monosaccharide is the most sweet?

• A. Glucose
• B. Dextrose
• C. Fructose
• D. Sucrose

Correct answer: C

Rationale: Fructose is the sweetest of the monosaccharides. Note that glucose and dextrose are the same, and sucrose is a disaccharide, not a monosaccharide.

5. Each of the following is a form of vitamin K, except one. Which is the exception?

• A. Phylloquinone
• B. Tocopherol
• C. Menaquinone
• D. Menadione

Correct answer: B

Rationale: Tocopherol, Choice B, is not a form of vitamin K; it is another name for vitamin E. Phylloquinone (Choice A), menaquinone (Choice C), and menadione (Choice D) are all forms of vitamin K. Phylloquinone is vitamin K1 found in green plants, menaquinone is vitamin K2 produced in the large intestine and found in animal tissues, and menadione is a synthetic form of vitamin K. Therefore, Choice B is the correct answer because it does not belong to the vitamin K group, unlike the other options.
