1. Macronutrients include each of the following except one. Which one is the exception?

• A. Fat
• B. Polyunsaturated fatty acids
• C. Carbohydrate
• D. Protein

Correct answer: D

Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.

2. 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.

3. The home health nurse visits older adult clients at an assisted living center. Which foods should the nurse recommend to correct the main nutrient deficits for this population?

• A. Carbohydrates
• B. Oily fish and krill oil
• C. Yellow vegetables
• D. Dairy products

Correct answer: D

Rationale: The correct answer is D: Dairy products. Older adults are often deficient in calcium and vitamin D, which are abundant in dairy products. These nutrients are essential for maintaining bone health. Choice A (Carbohydrates) is incorrect because while carbohydrates are an essential nutrient, they are not specifically addressing the main nutrient deficits for older adults. Choice B (Oily fish and krill oil) is incorrect as these foods are sources of omega-3 fatty acids and not specifically addressing the main nutrient deficits common in older adults. Choice C (Yellow vegetables) is incorrect because although vegetables are important for overall health, they do not directly address the main nutrient deficits typically seen in older adults.

4. A healthcare professional is reviewing the lab results of a client who has bulimia nervosa. The professional should notify the provider of which of the following results?

• A. White Blood Cells 5,200/mm³
• B. Hemoglobin 14 g/dL
• C. Magnesium 1.6 mg/dL
• D. Potassium 3.2 mEq/L

Correct answer: D

Rationale: A potassium level of 3.2 mEq/L is below normal and requires provider notification, especially in clients with bulimia nervosa who are at risk of electrolyte imbalances. Low potassium levels can lead to serious complications like cardiac arrhythmias. The other options are within or close to the normal range and would not be a priority for notification.

5. Which of the following is NOT a physiological role of proteins?

• A. Providing resistance to disease
• B. Regulating fluid balance
• C. Repairing tissue
• D. Serving as the primary source of energy

Correct answer: D

Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.
