ATI Nutrition Proctored Exam 2023

Correct Answer: A

Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.

Correct Answer: B

Rationale: The correct answer is B. The liver does not convert monosaccharides to triglycerides; instead, it converts monosaccharides to glucose or glycogen. Choice A is correct because the liver plays a role in regulating the levels of various nutrients in the bloodstream. Choice C is correct as the liver breaks down stored glycogen into glucose to maintain blood sugar levels. Choice D is correct as the liver oxidizes digestive end products to provide energy. Therefore, only choice B is incorrect as the liver does not convert monosaccharides to triglycerides.

Correct Answer: D

Rationale: The correct answer is D, Hypertension. Hypertension is not typically associated with underconsumption of fat; instead, it is more related to the consumption of excess fat, especially saturated and trans fats, which can contribute to increased blood pressure. Malabsorption syndromes, cystic fibrosis, and AIDS are conditions where underconsumption of fat can be a concern due to various reasons such as malabsorption issues, pancreatic insufficiency, or increased energy needs.

Correct Answer: C

Rationale: The best way to ensure adequate nutrition for a stroke patient who frequently chokes and coughs when eating and has difficulty feeding herself is to provide tube feedings. Tube feedings are a safe and effective method to deliver nutrition directly to the stomach or intestines, bypassing the swallowing mechanism, reducing the risk of aspiration. Having an aide feed her each meal (choice A) may not address the underlying issue of swallowing difficulty and aspiration risk. Asking a family member to be present at each meal (choice B) does not provide a definitive solution to the patient's nutritional needs. Placing the patient on total parenteral nutrition (TPN) (choice D) is a more invasive and typically reserved for patients who cannot tolerate enteral feedings or have non-functional gastrointestinal tracts.

Correct Answer: A

Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.
