ATI Nutrition Practice A

Correct Answer: B

Rationale: Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth by breaking down starches into simpler sugars.

Correct Answer: C

Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.

Correct Answer: D

Rationale: Coconut oil is a plant-based oil that is high in saturated fat, unlike most other plant oils, which are typically unsaturated.

Correct Answer: D

Rationale: Carbohydrates, fats, and proteins are the three macronutrients that provide energy (calories) to the body. Carbohydrates are the body's primary source of energy, fats act as a secondary source when carbohydrate energy is exhausted, and proteins are used for energy when carbohydrate and fat sources are low. Choice D, Water, is essential for the body's functions, but it does not provide energy.

Correct Answer: C

Rationale: The correct answer is C: Choose high-fat meat instead of lean meat. High-fat meats are more calorie-dense than lean meats, which makes them a good choice for increasing calorie intake. This is crucial for patients with stomach cancer who want to avoid weight loss and wasting. Choice A is incorrect because skim milk or water contains fewer calories than whole fat milk. Choice B is also incorrect because peanut butter and nuts are high in calories and therefore should not be avoided when trying to increase calorie intake. Finally, choice D is not a good suggestion to increase calorie intake as alcohol does not provide the necessary nutrients needed for a balanced diet. In fact, excessive alcohol can harm the liver and other organs, and it's not a reliable source of calories.
