1. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

2. The client is discussing sources of carbohydrates with a nurse recently diagnosed with diabetes. Which food(s) identified by the client indicate understanding? (SATA)

• A. Starch
• B. Fiber
• C. Sugar
• D. All of the above

Correct answer: D

Rationale: The correct answer is D because starch, fiber, and sugar are all sources of carbohydrates. Starchy foods like bread, rice, and potatoes contain starch; fruits, vegetables, and whole grains provide fiber; and sugars are found in sweet foods like fruits, honey, and desserts. Fatty acids and amino acids are not sources of carbohydrates, so choices A, B, and C are correct while choices A and B are incorrect.

3. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

4. A client with type 1 diabetes mellitus asks a nurse for a sweetener recommendation. Which of the following recommendations should the nurse make?

• A. Corn syrup
• B. Natural honey
• C. Nonnutritive sugar substitute
• D. Guava nectar

Correct answer: C

Rationale: The correct recommendation for a client with type 1 diabetes mellitus looking for a sweetener is a nonnutritive sugar substitute. Nonnutritive sugar substitutes do not significantly affect blood glucose levels, making them a suitable option for individuals with diabetes. Corn syrup and natural honey are high in sugar and can lead to spikes in blood glucose levels, which is not ideal for someone with diabetes. Guava nectar, while natural, is also high in sugar content and not recommended for individuals with diabetes.

5. A nurse is planning to teach a client about a low-potassium diet. Which of the following foods should the nurse instruct the client to avoid?

• A. Butter
• B. Poultry
• C. Yogurt
• D. Orange juice

Correct answer: D

Rationale: Orange juice is high in potassium and should be avoided in a low-potassium diet. Butter, poultry, and yogurt are low-potassium food choices and can be included in a low-potassium diet. Poultry is a good source of lean protein, yogurt is a good source of calcium and protein, and butter is low in potassium. Therefore, the nurse should instruct the client to avoid orange juice as it is high in potassium, which is not suitable for a low-potassium diet.
