ATI Nutrition Proctored

Correct Answer: A

Rationale: The correct answer is A: Iron. Iron is an essential nutrient needed by the body to make hemoglobin, the protein in red blood cells that carries oxygen. While other nutrients like vitamin B12, niacin, and folate are important for various bodily functions, they are not directly involved in the production of hemoglobin. Vitamin B12 is essential for nerve function and DNA synthesis, niacin is important for metabolism, and folate is crucial for cell division and DNA synthesis. Therefore, only iron is specifically required for hemoglobin production.

Correct Answer: B

Rationale: Abdominal pain is a common symptom of irritable bowel syndrome (IBS), along with bloating and changes in bowel habits. Rectal bleeding (choice A) is more commonly associated with conditions like inflammatory bowel disease or colorectal cancer. Rectal fissures (choice C) may cause rectal bleeding but are not typically considered a core symptom of IBS. Esophageal paralysis (choice D) is unrelated to the symptoms of IBS, which primarily affect the lower gastrointestinal tract.

Correct Answer: B

Rationale: The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.

Correct Answer: B

Rationale: The correct answer is B: eyes, nerves, and kidneys. In diabetes, major complications result from damage to small blood vessels that supply these organs. Damage to the eyes can lead to retinopathy, to the nerves causing neuropathy, and to the kidneys causing nephropathy. Choices A, C, and D are incorrect as they do not represent the typical major complications associated with diabetes.
