ATI Proctored Nutrition Exam

Correct Answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

Correct Answer: B

Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.

Correct Answer: C

Rationale: Zinc plays a critical role in wound healing due to its involvement in cell proliferation, immune function, and protein synthesis, all of which are essential for tissue repair.

Correct Answer: B

Rationale: The correct answer is B: Increased thirst, urination, and hunger. Uncontrolled type 1 diabetes typically presents with classic symptoms including polydipsia (increased thirst), polyuria (frequent urination), and polyphagia (increased hunger). These symptoms are often accompanied by weight loss due to the body's inability to properly utilize glucose for energy. Choices A, C, and D are incorrect as they do not align with the typical symptoms of uncontrolled type 1 diabetes. Depression, anxiety, fatigue, weight gain, macrosomia, food cravings, poor wound healing, blurred vision, and recurrent infections are not primary symptoms associated with uncontrolled type 1 diabetes.

Correct Answer: D

Rationale: Logical steps include evaluating the credibility of the website, reading official guidelines, comparing information from credible sources, and verifying the author's qualifications.
