ATI Nutrition Proctored Exam
1. Each is a physiologic role of vitamin D, except one. Which is the exception?
- A. Hematopoiesis
- B. Cardiac and neuromuscular function
- C. Immune responses
- D. Serum calcium regulation
Correct answer: A
Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.
2. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?
- A. A client who is postoperative following a laminectomy and is receiving IV PCA
- B. A client who has dysphagia and does not recognize his family
- C. A client who has COPD and is going home with oxygen
- D. A client who has colon cancer and will undergo a hemicolectomy
Correct answer: D
Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.
3. Which of the following nutrients deficiency may lead to a diabetes-like condition?
- A. chromium
- B. iron
- C. molybdenum
- D. selenium
Correct answer: A
Rationale: Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.
4. Which foods increase iron absorption when consumed with nonheme iron? (SATA)
- A. Kiwi
- B. Strawberries
- C. Coffee
- D. A, B
Correct answer: D
Rationale: Kiwi and strawberries are high in vitamin C, which increases iron absorption.
5. Why is there an ethical dilemma?
- A. Because the law does not clearly state what is right from what is wrong
- B. Because morality is subjective and it differs from each individual
- C. Because the patient's right coincide with the nurse's responsibility
- D. Because the nurse lacks ethical knowledge to determine what action is correct and what action is unethical
Correct answer: C
Rationale: The correct answer is C because an ethical dilemma arises when the patient's rights conflict with the nurse's responsibilities, requiring a careful balance to ensure ethical care delivery. Choices A and B are incorrect because ethical dilemmas are not solely about legal or subjective moral issues. Choice D is incorrect as nurses are generally equipped with ethical knowledge through education and training, and ethical dilemmas are more about conflicting values and responsibilities rather than a lack of knowledge.
