ATI Nutrition Practice A

1. What is the digestive action of bile?

Correct answer: D

Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.

2. Magnesium's major functions in the body would be least likely to include which of the following?

Correct answer: D

Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.

3. Which type of fatty acid has carbon atoms connected by two or more double bonds?

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.

4. When is Prevident indicated?

Correct answer: D

Rationale: Prevident is indicated for all the situations listed in the choices. It is recommended for patients with a high risk of caries to reduce the risk of tooth decay. It is also used in dental procedures like crown and bridge work to strengthen enamel and prevent cavities. Furthermore, it is utilized for orthodontic decalcification to aid in remineralizing the tooth structure and prevent further damage. Therefore, the correct answer is 'All of the above.' While choices A, B, and C are individually correct, selecting 'All of the above' is the most appropriate as it encompasses all the possible indications for Prevident.

5. A nurse is providing teaching to a group of older adults about sources of complete and incomplete protein. Which of the following foods should the nurse include as a complete protein?

Correct answer: A

Rationale: Yogurt is the correct answer as it is a complete protein source, containing all nine essential amino acids. Fresh vegetables, nuts, and dried beans are incomplete protein sources as they lack one or more essential amino acids required by the body.
