Nutrition ATI Proctored Exam 2023
1. The nurse is caring for an infant whose parent reports the infant takes a bottle to go to sleep. What should the nurse instruct to prevent baby bottle tooth decay?
- A. Water
- B. Milk
- C. Iron-fortified formula
- D. Unsweetened fruit juice
Correct answer: A
Rationale: The correct answer is A, Water. Water is recommended to prevent baby bottle tooth decay caused by sugary substances present in milk, formula, or fruit juice. Water does not contain sugars that can contribute to tooth decay, unlike the other options. Milk, formula, and unsweetened fruit juice can all lead to tooth decay if the baby falls asleep with them in their mouth, as the sugars can linger on the teeth and cause decay over time. Iron-fortified formula, although beneficial for the infant's nutrition, still contains sugars that can be harmful to the teeth.
2. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?
- A. Natural active immunity
- B. Natural passive immunity
- C. Artificial active immunity
- D. Artificial passive immunity
Correct answer: B
Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.
3. A client receiving total parenteral nutrition (TPN is awaiting the next container. What fluid should the nurse infuse in the interim?
- A. Dextrose 5% in water
- B. 0.9% sodium chloride
- C. Dextrose 10% in water
- D. Lactated Ringer's solution
Correct answer: B
Rationale: The correct answer is 0.9% sodium chloride. When a client receiving TPN is awaiting the next container, infusing 0.9% sodium chloride is the appropriate choice to maintain fluid and electrolyte balance. Dextrose solutions are not recommended as they do not provide sufficient nutrition. Lactated Ringer's solution contains electrolytes but lacks essential nutrients found in TPN, making it an inadequate choice during the delay in TPN delivery.
4. Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:
- A. they must be supplied by the diet
- B. they can be produced by a process called dehydrogenation
- C. they are anti-inflammatory
- D. they are all polyunsaturated fatty acids
Correct answer: A
Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.
5. When is infertility said to exist?
- A. When a woman has no uterus
- B. When a woman has no children
- C. When a couple has been trying to conceive for 1 year without success
- D. When a couple has desired a child for 6 months
Correct answer: C
Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.
