PN Nutrition Assessment ATI
1. Individuals with optimal nutritional status differ from those with marginal nutritional status in their:
- A. nutrient reserves.
- B. clinical signs.
- C. body weight.
- D. risk of mental illness.
Correct answer: A
Rationale: Individuals with optimal nutritional status differ from those with marginal nutritional status in their nutrient reserves. Optimal nutritional status implies having adequate nutrient reserves, which is lacking in marginal status. Clinical signs (choice B) may or may not be present in both groups and are not the differentiating factor between optimal and marginal statuses. Body weight (choice C) can vary for reasons other than nutritional status. The risk of mental illness (choice D) is not directly related to the comparison between optimal and marginal nutritional status.
2. How many kilocalories are provided by 15 grams of protein?
- A. 15
- B. 45
- C. 60
- D. 135
Correct answer: C
Rationale: Protein provides 4 kcal per gram. Therefore, 15 grams of protein will provide 15 grams x 4 kcal/gram = 60 kcal. Choices A, B, and D are incorrect because they do not consider the caloric value of protein correctly.
3. Individual nutrients are characterized by their ability to:
- A. work independently.
- B. fulfill specific metabolic roles.
- C. influence weight loss.
- D. improve mental status.
Correct answer: B
Rationale: The correct answer is B: 'fulfill specific metabolic roles.' Nutrients play essential roles in specific metabolic processes in the body such as energy production, tissue repair, and growth. Choice A, 'work independently,' is incorrect as nutrients often work synergistically rather than alone. Choice C, 'influence weight loss,' is incorrect as while some nutrients may support weight loss indirectly through metabolic processes, it is not their primary characteristic. Choice D, 'improve mental status,' is also incorrect as while some nutrients are important for brain health, their primary role is not specifically to improve mental status.
4. Which pathogenic bacterium is associated with peptic ulcer disease and gastric cancer?
- A. Lactobacillus.
- B. Bifidobacterium.
- C. H. pylori.
- D. E. coli.
Correct answer: C
Rationale: The correct answer is H. pylori. This bacterium is known to be associated with the development of peptic ulcers and an increased risk of gastric cancer. Lactobacillus (Choice A) and Bifidobacterium (Choice B) are probiotic bacteria that are beneficial to human health and not associated with causing these conditions. E. coli (Choice D) is a diverse group of bacteria, some of which can be pathogenic, but they are not primarily linked to peptic ulcers and gastric cancer like H. pylori.
5. Most fat replacers are made from:
- A. proteins.
- B. carbohydrates.
- C. cholesterol.
- D. monoglycerides.
Correct answer: B
Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.
