ATI Proctored Nutrition Exam
1. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: B
Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.
2. A dental hygienist finds several new carious lesions in a patient with chronic obstructive respiratory disease (COPD). While conducting the medical and dental histories, the dental hygienist is most likely to find an increased use of which of the following?
- A. Protein
- B. Cough drops
- C. Fluoride
- D. Xylitol
Correct answer: B
Rationale: The correct answer is B: Cough drops. Patients with COPD often use cough drops to manage their symptoms, which can lead to an increase in carious lesions due to their sugar content. Choices A, C, and D are incorrect as protein, fluoride, and xylitol are not typically associated with an increased risk of carious lesions in patients with COPD.
3. What is the desirable resting systolic blood pressure for adults?
- A. <130 mmHg>
- B. <105 mmHg>
- C. <120 mmHg>
- D. <140 mmHg>
Correct answer: C
Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.
4. A nurse is teaching a client about complete and incomplete proteins. Which of the following foods should the nurse include in the teaching as an incomplete protein?
- A. 4 oz chickpeas
- B. 2 poached eggs
- C. 2 oz cheddar cheese
- D. 4 oz salmon fillet
Correct answer: A
Rationale: The correct answer is A: 4 oz chickpeas. Chickpeas are considered an incomplete protein because they lack one or more essential amino acids required by the body. Incomplete proteins do not provide all essential amino acids in sufficient quantities. Choice B, 2 poached eggs, is a complete protein source because eggs contain all essential amino acids. Choice C, 2 oz cheddar cheese, is also a complete protein as it contains all essential amino acids. Choice D, 4 oz salmon fillet, is another complete protein source as fish typically provide all essential amino acids needed by the body.
5. Which type of fatty acid has carbon atoms connected by two or more double bonds?
- A. Saturated fatty acids
- B. Monounsaturated fatty acids
- C. Trans fatty acids
- D. Polyunsaturated fatty acids
Correct answer: D
Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.
