ATI Proctored Nutrition Exam 2019

1. Obsessive compulsive disorder is classified under:

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

2. Which enzyme is most essential for hydrolyzing large protein molecules?

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

3. What is tocopherol?

Correct answer: D

Rationale: Tocopherol is another name for Vitamin E, a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Choices A, B, and C are incorrect as tocopherol is specifically related to Vitamin E and not Vitamin B1, B2, or B3.

4. To raise HDL levels, what is Mrs. Smith advised to do?

Correct answer: A

Rationale: The correct answer is A: quit smoking. Smoking lowers HDL levels, so quitting smoking is crucial to raising HDL levels. Increasing dietary sodium (choice B) is not linked to raising HDL levels and can have negative effects on cardiovascular health. Taking iron supplements (choice C) is not directly related to increasing HDL levels. Avoiding dairy products (choice D) is not necessary to raise HDL levels; in fact, some dairy products like low-fat options can be part of a heart-healthy diet.

5. The most energy-rich nutrient is:

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.
