ATI Proctored Nutrition Exam

1. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

2. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.

Correct answer: C

Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.

3. The following are all classes of nutrients except:

Correct answer: D

Rationale: Phytochemicals are not considered a class of nutrients. While proteins, fats, and carbohydrates are essential macronutrients providing energy and structural support, phytochemicals are non-nutrient compounds found in plants that offer various health benefits but are not essential for sustaining life like the other three choices. Therefore, the correct answer is D.

4. What is the term for a barrier that prevents the normal emptying of stomach contents into the duodenum?

Correct answer: C

Rationale: Gastric outlet obstruction refers to a condition where the opening between the stomach and the duodenum is blocked, preventing the normal passage of food. This is why choice 'C' is correct. 'A: Dumping syndrome' is incorrect because it is a condition where stomach contents move too quickly through the small intestine, not a barrier preventing emptying. 'B: Gastritis' is inflammation of the stomach lining, not a blockage of the outlet. 'D: Hypochlorhydria' refers to low stomach acid, which may affect digestion but does not create a physical barrier blocking the outlet of the stomach.

5. What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?

Correct answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.
