ATI Nutrition Proctored Exam 2023
1. Does the reduction in oxidative damage that occurs with energy restriction in animals also occur in people whose diets include _____?
- A. fiber and carbohydrates
- B. fatty acids and protein
- C. probiotics
- D. antioxidants and phytochemicals
Correct answer: D
Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.
2. What activities best describe the work of the placenta during pregnancy?
- A. surrounding and cushioning the fetus
- B. combining maternal and fetal blood stores to exchange nutrients
- C. producing hormones that maintain the pregnancy
- D. absorbing vitamins and minerals that can be transferred to the fetus
Correct answer: C
Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.
3. Which dietary supplement is often recommended for patients taking statins to lower cholesterol?
- A. Iron
- B. Coenzyme Q10
- C. Calcium
- D. Magnesium
Correct answer: B
Rationale: Coenzyme Q10 is often recommended for patients on statins because it may help reduce muscle pain, a common side effect of these medications. Iron (Choice A) is not typically recommended for patients taking statins to lower cholesterol. Calcium (Choice C) and Magnesium (Choice D) are not specifically indicated for addressing muscle pain associated with statin use, making them less suitable choices in this scenario.
4. Knowing that for a comatose patient hearing is the last sense to be lost, as Judy’s nurse, what should you do?
- A. Tell her family that probably she can’t hear them
- B. Talk loudly so that Wendy can hear you
- C. Tell her family who are in the room not to talk
- D. Speak softly then hold her hands gently
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.
5. Which of the following is not a desirable blood lipid value?
- A. low total cholesterol
- B. high LDL
- C. high HDL
- D. low blood triglycerides
Correct answer: B
Rationale: The correct answer is B. High levels of LDL (low-density lipoprotein) cholesterol are undesirable as they are associated with an increased risk of cardiovascular disease. Therefore, low total cholesterol (choice A), high HDL (choice C), and low blood triglycerides (choice D) are considered desirable blood lipid values. Low total cholesterol is beneficial as high levels can increase the risk of heart disease. High HDL cholesterol is considered good as it helps remove LDL cholesterol from the arteries. Low blood triglycerides are also preferred as high levels are associated with an increased risk of heart disease.
