PN Nutrition Assessment ATI
1. Which of the following provides the best source of nutrients?
- A. specific food combinations.
- B. a variety of foods.
- C. individual foods.
- D. a variety of food supplements.
Correct answer: B
Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.
2. Which nutrient group provides the primary source of energy for the body?
- A. Carbohydrates.
- B. Fats.
- C. Proteins.
- D. Vitamins.
Correct answer: A
Rationale: Carbohydrates are the body's primary source of energy. When carbohydrates are consumed, they are broken down into glucose, which is used by the body's cells for energy production. Fats and proteins are also essential nutrients, but carbohydrates are the preferred energy source for the body due to their quick conversion into fuel. Vitamins are not a direct source of energy but play crucial roles in various bodily functions.
3. Why is it important to understand standard serving sizes of foods?
- A. it is easy to eat too much of some nutrients when choosing healthful foods.
- B. serving sizes have generally decreased over the past few decades.
- C. most people have difficulty estimating the amount of food they eat.
- D. food portions need to be weighed to check serving sizes accurately.
Correct answer: C
Rationale: The correct answer is C. Understanding serving sizes is crucial because most people have difficulty estimating the amount of food they eat. It helps individuals accurately track their intake, which is essential for maintaining a healthy diet and avoiding overeating. Choice A is incorrect because the question focuses on portion sizes rather than specific nutrients. Choice B is incorrect as it presents an unsupported claim about serving sizes decreasing. Choice D is incorrect as weighing food portions is not always necessary to check serving sizes; understanding standard serving sizes allows for a more practical approach to portion control.
4. Signs of malnutrition can appear when:
- A. nutrient reserves are depleted.
- B. nutrient intake exceeds daily needs.
- C. energy intake is restricted.
- D. caloric expenditure increases.
Correct answer: A
Rationale: The correct answer is A: 'nutrient reserves are depleted.' Signs of malnutrition manifest when the body's reserves of essential nutrients are exhausted and can no longer sustain health. Choice B is incorrect because excessive nutrient intake exceeding daily needs does not lead to malnutrition but may cause other health issues. Choice C is incorrect as restricting energy intake may lead to weight loss but not necessarily malnutrition. Choice D is also incorrect as increasing caloric expenditure does not directly cause malnutrition.
5. The major focus of nutritional recommendations in this century has shifted to:
- A. prevention and control of chronic diseases.
- B. improved sanitation and public health.
- C. prevention and control of infectious diseases.
- D. development of healthful foods using food technology.
Correct answer: A
Rationale: The correct answer is A: prevention and control of chronic diseases. In this century, nutritional recommendations have increasingly emphasized the importance of preventing and managing chronic diseases like obesity, diabetes, cardiovascular diseases, and cancer. Lifestyle factors such as diet play a significant role in the development of these conditions. Option B, improved sanitation and public health, although important for overall health, is not the primary focus of nutritional recommendations. Option C, prevention and control of infectious diseases, is also crucial but does not reflect the current major focus of nutritional recommendations. Option D, development of healthful foods using food technology, is a valid area of interest but is not the primary shift in focus observed in nutritional recommendations.
