ATI Nutrition Proctored Exam 2023
1. Which mineral is a principal component of cell membranes?
- A. phosphorus
- B. magnesium
- C. iron
- D. iodine
Correct answer: A
Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.
2. A patient is on a low-sodium diet. Which food item should the patient avoid?
- A. Fresh fruit
- B. Canned soup
- C. Whole grain bread
- D. Grilled chicken
Correct answer: B
Rationale: The correct answer is B: Canned soup. Canned soup is commonly high in sodium content, which is not suitable for a patient on a low-sodium diet. Fresh fruit, whole grain bread, and grilled chicken typically have lower sodium levels and can be included in a low-sodium diet. Therefore, the patient should avoid canned soup to adhere to the requirements of a low-sodium diet.
3. Which of the following amino acids are considered indispensable?
- A. Lysine
- B. Methionine
- C. Tryptophan
- D. Valine
Correct answer: A
Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
4. A nurse is teaching a parent about appropriate snack choices for her 9-month-old infant. Which of the following food choices should the nurse recommend?
- A. Skim milk
- B. Unsalted popcorn
- C. Graham crackers
- D. Raw carrots
Correct answer: C
Rationale: Graham crackers are an appropriate snack choice for a 9-month-old infant due to their texture and ease of consumption. Skim milk (Choice A) is not recommended for infants under 1 year old due to the potential risk of developing milk allergies. Unsalted popcorn (Choice B) can be a choking hazard for infants. Raw carrots (Choice D) are a potential choking hazard for a 9-month-old infant and may be difficult for them to chew and digest.
5. A condition that often progresses to become type 2 diabetes mellitus is:
- A. type 1 diabetes mellitus
- B. high blood pressure
- C. chronic pancreatitis
- D. impaired glucose tolerance
Correct answer: D
Rationale: Impaired glucose tolerance is a pre-diabetic state characterized by higher than normal blood sugar levels. It is often associated with insulin resistance and can progress to type 2 diabetes mellitus. Type 1 diabetes mellitus (Choice A) is an autoimmune condition where the body attacks insulin-producing cells, leading to a lack of insulin production. High blood pressure (Choice B) and chronic pancreatitis (Choice C) are not directly linked to the progression to type 2 diabetes mellitus.
