ATI RN
Nutrition ATI Proctored Exam 2023
1. Mang Carlos has a standing DNR order. He then suddenly stopped breathing and you are at his bedside. You would:
- A. Give extraordinary measures to save Mang Carlos
- B. Stay with Mang Carlos and Do nothing
- C. Call the physician
- D. Activate Code Blue
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
2. A nurse is reviewing blood glucose values for a client who is at risk for Diabetes Mellitus. Which of the following findings should the nurse report to the provider?
- A. 2-hour glucose tolerance test level 150 mg/dL
- B. Fasting blood glucose 70 mg/dL
- C. Glycosylated hemoglobin 5%
- D. Casual blood glucose 90 mg/dL
Correct answer: A
Rationale: The correct answer is A. A 2-hour glucose tolerance test level of 150 mg/dL is above the normal range and should be reported to the provider as it indicates impaired glucose tolerance. Choice B (Fasting blood glucose 70 mg/dL) is within the normal range. Choice C (Glycosylated hemoglobin 5%) is also within the normal range. Choice D (Casual blood glucose 90 mg/dL) is within the normal range and does not indicate impaired glucose tolerance.
3. What best describes a task of the registered dietitian?
- A. administering total parenteral nutrition
- B. administering formula through feeding tubes
- C. prescribing diet orders
- D. conducting nutrition assessments
Correct answer: D
Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.
4. Each statement is true of proteins, except one. Which is the exception?
- A. Proteins are composed of building blocks called amino acids
- B. The classification of the 20 common amino acids is based on the properties of their side chains
- C. The general structure of an amino acid varies considerably
- D. Amino acids polymerize to form long chains called polypeptides
Correct answer: B
Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.
5. A nurse is caring for a client with a major burn injury and is receiving TPN. Which of the following lab tests is the priority for the nurse to use to confirm the client is receiving adequate nutrition?
- A. Iron
- B. Magnesium
- C. Folic acid
- D. Prealbumin
Correct answer: D
Rationale: Prealbumin is a sensitive indicator of protein status and nutrition, making it a priority for assessing nutritional adequacy in clients receiving TPN. Iron, magnesium, and folic acid levels are important for overall health but do not specifically indicate nutritional adequacy in the context of TPN administration.
