ATI RN

ATI Nutrition Proctored Exam 2023

1. Which of the following statements is false?

A. People with a vitamin K deficiency experience increased clotting time
B. The major function of vitamin E is promoting vision
C. Vitamin D functions as a hormone
D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.

2. Match amylase with its digestive action:

A. breaks down carbs
B. breaks down proteins
C. breaks down lipids
D. helps fat digestion

Correct answer: A

Rationale: The correct answer is A: 'breaks down carbs.' Amylase is an enzyme that specifically targets carbohydrates, breaking them down into simpler sugars like maltose. This process aids in the digestion of carbohydrates in the human body. Choices B, C, and D are incorrect because amylase does not break down proteins, lipids, or directly aid fat digestion. Proteins are broken down by proteases, lipids are broken down by lipases, and fat digestion is primarily assisted by bile salts and lipases in the small intestine.

3. A nurse is providing anticipatory guidance to a client who has Phenylketonuria (PKU) and is planning a pregnancy. Which of the following information should the nurse include in the discussion?

A. Diet sodas should not be consumed more than two or three times a week.
B. Serum bilirubin should be monitored once or twice a month during pregnancy.
C. Breastfeeding will not prevent your baby from developing PKU.
D. A low-protein diet should be followed for three months before conception.

Correct answer: D

Rationale: A low-protein diet should be followed for three months before conception in individuals with PKU who are planning a pregnancy. This diet helps manage PKU by reducing phenylalanine levels, which is crucial for maternal and fetal health. Choices A, B, and C are incorrect. Choice A is not directly related to managing PKU, choice B focuses on a different aspect of care during pregnancy, and choice C is inaccurate as breastfeeding will not prevent a baby from developing PKU.

4. A client with a body mass index of 28 is seeking dietary advice. Which of the following actions should the nurse take?

A. Encourage the client to continue their current daily caloric intake.
B. Recommend a total fiber intake of 12g per day.
C. Advise the client to add 500 calories per day to their diet.
D. Refer the client to a weight-loss support group.

Correct answer: D

Rationale: Referring the client to a weight-loss support group is the most appropriate action for a client with a body mass index of 28. This action can provide the necessary support, guidance, and motivation to help the client achieve their weight loss goals. Encouraging the client to continue their current daily caloric intake (Choice A) may not address the need for weight loss. Recommending a total fiber intake of 12g per day (Choice B) is important for overall health but may not directly address weight loss. Advising the client to add 500 calories per day to their diet (Choice C) would not be beneficial for weight loss in this scenario.

5. A nurse is discussing denture care with the partner of a client who is unable to perform oral hygiene. Which of the following should be included in the discussion?

A. Floss dentures as part of daily cleaning.
B. Wipe dentures before storing them in a dry container at night.
C. Wrap gloved fingers with gauze to remove dentures.
D. Use a washcloth to clean the denture surfaces.

Correct answer: C

Rationale: The correct answer is C: 'Wrap gloved fingers with gauze to remove dentures.' This method provides a safe and effective way to remove dentures without causing damage. Choice A is incorrect because flossing dentures is not recommended. Choice B is incorrect as it suggests wiping dentures and storing them dry, which is not the best practice. Choice D is incorrect because using a washcloth may not effectively clean all denture surfaces.
