1. In persons who are obese, weight reduction can improve such CHD risk factors as hypertension, blood lipid abnormalities, and?
- A. inflammation
- B. insulin resistance
- C. gastrointestinal motility disorders
- D. damage from cigarette smoking
Correct answer: B
Rationale: Weight reduction in obese individuals can improve insulin resistance, a key factor in reducing the risk of coronary heart disease and type 2 diabetes.
2. A nurse is providing MyPlate education to a client newly diagnosed with diabetes mellitus. Which plate chosen by the client indicates the teaching was effective, according to the MyPlate guidelines?
- A. 1/2 of the plate is filled with carbohydrate foods, 1/4 filled with protein foods, and 1/4 filled with fruits and vegetables
- B. 1/2 of the plate is filled with protein foods, 1/4 filled with carbohydrates, and 1/4 filled with non-starchy vegetables
- C. 1/2 of the plate is filled with carbohydrates, 1/4 filled with protein foods, and 1/4 filled with non-starchy vegetables
- D. 1/2 of the plate is filled with non-starchy vegetables, 1/4 filled with protein foods, and 1/4 filled with carbohydrate foods
Correct answer: D
Rationale: The correct answer is D. This option reflects the MyPlate guidelines for managing diabetes effectively. In diabetes management, it is essential to focus on non-starchy vegetables, appropriate protein portions, and controlled carbohydrate intake. Option A places too much emphasis on carbohydrates, which may not be suitable for diabetes. Option B swaps the proportions of protein and carbohydrates, which is not in line with the recommended distribution. Option C places too much emphasis on carbohydrates and lacks the emphasis on non-starchy vegetables, making it less suitable for diabetes management.
3. Low levels of high-density lipoproteins (HDL) are?
- A. associated with being underweight
- B. more prevalent in males
- C. highly predictive of CHD risk
- D. not a good predictor of CHD risk
Correct answer: C
Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.
4. How many grams of protein per day are recommended for a person weighing 150 lbs?
- A. 120
- B. 85
- C. 187.5
- D. 54
Correct answer: D
Rationale: The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.
5. What is the most significant dietary influence on the development of dental caries?
- A. Carbohydrates
- B. Vitamins
- C. Minerals
- D. Fats
Correct answer: A
Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.
