Nutrition ATI Proctored Exam

Correct Answer: D

Rationale: Option A is correct because lipoproteins indeed transport lipids in the blood. They are complexes of lipids and proteins that transport water-insoluble lipids through the blood. Option B is correct as it accurately describes the condition of type II diabetes where the pancreas can produce insulin, but the cells are resistant to its signal, causing an ineffective regulation of blood sugar. Option C is also correct because the glycemic index is indeed a classification system for foods based on their potential to raise blood glucose levels. High glycemic index foods raise blood glucose levels faster than low glycemic index foods. Hence, all the statements are correct, making option D the correct answer.

Correct Answer: B

Rationale: Malnutrition is a common comorbidity in patients with Chronic Kidney Disease (CKD). This is mainly due to factors such as dietary restrictions, poor appetite, and the body's increased nutritional needs as it struggles to deal with the disease. Liver disease (Choice A) is not typically associated directly with CKD, although both conditions may coexist in some patients. Acute renal failure (Choice C) is not a comorbidity but a severe and potentially lethal progression of CKD. Difficulty breathing (Choice D) is not a comorbidity but can be a symptom of severe kidney disease or other underlying conditions. However, malnutrition is more commonly observed in CKD patients compared to difficulty breathing.

Correct Answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

Correct Answer: B

Rationale: Iron is an essential nutrient for the body, and while it can be found in many different types of foods, the amounts can vary significantly. Cheese, while a good source of other nutrients like calcium and protein, is not a particularly rich source of iron. On the other hand, clams, legumes, and dried fruits are known to contain higher levels of iron. Therefore, among the provided choices, cheese is considered a poor source of iron. It's important to note that a balanced diet should include a variety of foods to ensure the intake of all necessary nutrients.

Correct Answer: A

Rationale: Patients with periodontal disease may require increased protein intake due to the physiological response to inflammation and infection, which can negatively impact protein synthesis. Protein is essential for wound healing and tissue repair, and an infection can increase the body's protein requirements. Therefore, ensuring an adequate protein intake is particularly important for these patients. Choice A is correct because the statement and reason are both accurate and directly related to each other, supporting the increased protein needs in patients with periodontal disease. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.
