ATI Nutrition Proctored Exam
1. Each of the following describes the physiologic roles of water, except one. Which is the exception?
- A. Acts as a solvent for chemical reactions.
- B. Maintains stability of body fluids.
- C. Enables transport of nutrients and excretion of waste.
- D. Regulates temperature by pooling as perspiration on skin.
Correct answer: D
Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.
2. Which of the following gauges should you prepare for spinal anesthesia if the anesthesiologist requires a pink spinal set and a blue spinal set as backup?
- A. Gauges 16 and 22
- B. Gauges 18 and 16
- C. Gauges 16 and 20
- D. Gauges 25 and 22
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
3. What is a disadvantage of using a food frequency questionnaire?
- A. It does not influence the food choices of the consumer
- B. It is not affected by seasonal changes in the diet
- C. It is not effective for monitoring short-term changes in food intake
- D. It does not take too long to obtain the results
Correct answer: C
Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.
4. Does the reduction in oxidative damage that occurs with energy restriction in animals also occur in people whose diets include _____?
- A. fiber and carbohydrates
- B. fatty acids and protein
- C. probiotics
- D. antioxidants and phytochemicals
Correct answer: D
Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.
5. During times of staff and financial shortage, which method is the best and most effective?
- A. Functional Method
- B. Primary Nursing
- C. Team Nursing
- D. Modular Method
Correct answer: D
Rationale: During times of staff and financial shortage, the Modular Method is considered the best and most effective. This method allows for flexibility and adaptability in assigning tasks and responsibilities, making it easier to cope with limited resources. Functional Method (Choice A) focuses on the division of labor based on each staff member's skills, which may not be the most efficient during shortages. Primary Nursing (Choice B) and Team Nursing (Choice C) may require a more significant number of staff, making them less suitable during shortages.
