Nutrition ATI Proctored Exam
1. What is the major diet-derived antioxidant found in cell membranes?
- A. B12
- B. beta-carotene
- C. vitamin E
- D. vitamin A
Correct answer: C
Rationale: The correct answer is vitamin E. Vitamin E is the major antioxidant found in cell membranes, where it plays a crucial role in protecting them from oxidative damage. Although B12, beta-carotene, and vitamin A are important nutrients with specific functions in the body, they are not the primary antioxidants found in cell membranes. Vitamin E specifically localizes in cell membranes to neutralize free radicals and prevent lipid peroxidation, making it an essential antioxidant for cellular health.
2. Where does most nutrient digestion and absorption occur?
- A. Large intestine
- B. Small intestine
- C. Stomach
- D. Mouth
Correct answer: B
Rationale: The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.
3. 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.
4. Ms. ANA had a car accident where he lost her boyfriend. As a result, she became passive and submissive. The nurse knows that the type of crisis Ms. ANA is experiencing is:
- A. Developmental crisis
- B. Maturational crisis
- C. Situational crisis
- D. Social Crisis
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.
5. Which type of lipid is solid at room temperature?
- A. Cholesterol
- B. Phospholipid
- C. Saturated fat
- D. Trans fat
Correct answer: C
Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.
