ATI Nutrition Practice Test B 2019
1. The nurse is completing a nutritional assessment on a client. Which statement made by the client is most concerning to the nurse?
- A. "I notice when I take a vitamin E supplement, I bruise more easily."
- B. "I work nights and rarely go outside during the day."
- C. "I take warfarin, so I need to limit the amount of green leafy vegetables I eat."
- D. "My vitamin supplement has the recommended daily allowance of vitamin A."
Correct answer: A
Rationale: The correct answer is A. Excessive intake of vitamin E can increase the risk of bleeding as it acts as a blood thinner. Bruising easily may indicate too much vitamin E. Choice B is not as concerning as it describes a lifestyle that may lead to vitamin D deficiency due to lack of sunlight exposure. Choice C shows awareness of the interaction between warfarin and vitamin K, which is expected. Choice D indicates knowledge of the vitamin A content in the supplement, which is not a cause for concern.
2. What is the glomerular filtration rate for patients with stage 5 chronic kidney disease (CKD)?
- A.
- B.
- C.
- D.
Correct answer: A
Rationale:
3. Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
4. How many amino acids are essential?
- A. 5
- B. 7
- C. 9
- D. 13
Correct answer: C
Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.
5. A nurse is providing teaching about formula feeding to the parents of an infant. Which of the following instructions should the nurse include?
- A. Formula that remains in the bottle should not be used for one more feeding.
- B. Formula should be changed to whole milk when the infant is 12 months old.
- C. If the infant is gaining weight too rapidly, do not dilute the formula.
- D. If the infant turns away after taking most of the feeding, stop the feeding.
Correct answer: D
Rationale: If the infant turns away after taking most of the feeding, it indicates they are full, and continuing to feed may lead to overfeeding. Choice A is incorrect because it is not safe to use formula that remains in the bottle for another feeding due to the risk of bacterial contamination. Choice B is incorrect as whole milk should be introduced after the infant is 12 months old, not 9 months old. Choice C is incorrect as diluting formula can compromise the infant's nutrition and should not be done without healthcare provider guidance.
