ATI Nutrition Practice Test A 2019
1. What happens when Mrs. Guevarra, a nurse, delegates aspects of the client's care to the nurse-aide, an unlicensed staff member?
- A. Mrs. Guevarra makes the assignment to instruct the staff member
- B. Mrs. Guevarra is assigning the responsibility to the aide but not the accountability for those tasks
- C. Mrs. Guevarra does not need to directly supervise or evaluate the aide
- D. Mrs. Guevarra must know how to perform the task being delegated
Correct answer: C
Rationale: The correct answer is C. While it is true that Mrs. Guevarra is delegating tasks to the nurse-aide, she does not necessarily have to directly supervise or evaluate the aide. She still retains the overall accountability for the care of the client, but direct supervision of the aide is not a requirement for delegation. Choice A is incorrect because the primary purpose of delegation is not instruction. Choice B is also incorrect because although Mrs. Guevarra is delegating tasks, she still retains accountability for those tasks. Finally, choice D is incorrect because the ability to perform the task being delegated is not a requirement for the delegator; the delegatee should have the necessary skills and knowledge to perform the delegated tasks.
2. Which student lunch is the least nutritious?
- A. Ham sandwich, apple, and milk
- B. Hamburger, fries, and soft drink
- C. Macaroni and cheese, green beans, and peaches
- D. Meatloaf, broccoli, and pear slices
Correct answer: B
Rationale: The correct answer is B - 'Hamburger, fries, and soft drink' as it contains foods high in unhealthy fats, sugars, and low nutritional value. A hamburger, fries, and a soft drink are considered less nutritious compared to the other options. Choice A includes a ham sandwich, apple, and milk, which provide a balance of protein, fiber, and calcium. Choice C consists of macaroni and cheese, green beans, and peaches, offering a mix of carbohydrates, vegetables, and fruits. Choice D contains meatloaf, broccoli, and pear slices, which provide a good source of protein, vitamins, and fiber. Therefore, option B is the least nutritious among the given choices.
3. An essential nutrient must:
- A. be eaten every day
- B. be obtained by the diet
- C. be water soluble
- D. be eaten at every meal
Correct answer: B
Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.
4. Which enzyme is most essential for hydrolyzing large protein molecules?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
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.
5. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
