1. What percentage of body weight as fat does a woman with a healthy body composition typically average?

• A. 5%
• B. 15%
• C. 25%
• D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

2. A nurse is educating a group of older adults in a community center on weight management using the BMI scale. Using the client's height and weight to calculate BMI, which of the following clients has a healthy BMI?

• A. A client with a weight of 128 lb and height of 70 inches
• B. A client with a weight of 150 lb and height of 68 inches
• C. A client with a weight of 200 lb and height of 72 inches
• D. A client with a weight of 133 lb and height of 60 inches

Correct answer: A

Rationale: To determine a healthy BMI, we need to calculate it using the formula: BMI = weight (lbs) / height^2 (inches) x 703. For choice A, BMI = 128 / (70 x 70) x 703 = 18.38, which falls within the healthy BMI range of 18.5-24.9. Therefore, choice A is correct. Choices B, C, and D have BMIs of 22.8, 27.1, and 26.1, respectively, which are outside the healthy range. Thus, choices B, C, and D are incorrect.

3. What is the primary purpose of dietary fiber in the diet?

• A. Improving digestion
• B. Providing energy
• C. Aiding in the absorption of vitamins
• D. Reducing cholesterol

Correct answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.

4. What is tocopherol?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin E

Correct answer: D

Rationale: Tocopherol is another name for Vitamin E, a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Choices A, B, and C are incorrect as tocopherol is specifically related to Vitamin E and not Vitamin B1, B2, or B3.

5. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.
