ATI Nutrition Proctored Exam 2023
1. An essential nutrient must:
- A. be eaten every day
- B. be obtained by the diet
- C. be water soluble
- D. be eaten at every meal
Correct answer: B
Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.
2. Which factor contributes to the development of bone diseases in patients with Chronic Kidney Disease (CKD) due to retention?
- A. Iron
- B. Sodium
- C. Potassium
- D. Phosphorus
Correct answer: D
Rationale: The correct answer is phosphorus. Retention of phosphorus in patients with Chronic Kidney Disease (CKD) contributes to the development of bone disorders, including osteodystrophy, because it disrupts the balance of calcium and phosphorus in the body. This imbalance leads to a variety of bone diseases. The other options - iron, sodium, and potassium - while important in the overall metabolic function, are not directly linked to the development of bone diseases in CKD patients due to retention.
3. A client with type 1 diabetes mellitus asks a nurse for a sweetener recommendation. Which of the following recommendations should the nurse make?
- A. Corn syrup
- B. Natural honey
- C. Nonnutritive sugar substitute
- D. Guava nectar
Correct answer: Nonnutritive sugar substitute
Rationale: The correct recommendation for a client with type 1 diabetes mellitus looking for a sweetener is a nonnutritive sugar substitute. Nonnutritive sugar substitutes do not significantly affect blood glucose levels, making them a suitable option for individuals with diabetes. Corn syrup and natural honey are high in sugar and can lead to spikes in blood glucose levels, which is not ideal for someone with diabetes. Guava nectar, while natural, is also high in sugar content and not recommended for individuals with diabetes.
4. What is a major constituent of cell membranes?
- A. cholesterol
- B. phospholipid
- C. saturated
- D. triglyceride
Correct answer: B
Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.
5. By the age of three, which age-appropriate food skill can a child typically perform?
- A. Using utensils and a napkin
- B. Spearing food with a fork
- C. Measuring liquids
- D. Displaying proper table manners
Correct answer: B
Rationale: By the age of three, a child typically develops the motor skills needed to spear food with a fork. This is a critical milestone in self-feeding as it shows progress in fine motor coordination. Choice 'A' is incorrect because using utensils and a napkin properly is a skill that may take longer to develop and refine. Choice 'C' is not correct as measuring liquids requires a higher level of motor skills and understanding of quantities that a three-year-old child might not possess. Choice 'D' is also incorrect as the proper display of table manners is a complex skill that is typically learned over a longer period and involves social and cultural norms.
