ATI Nutrition Practice A
1. Starting material for sex hormones:
- A. cholesterol
- B. phospholipid
- C. saturated
- D. triglyceride
Correct answer: A
Rationale: Cholesterol is a precursor for the synthesis of sex hormones like estrogen and testosterone.
2. The PEM in which children ages 18-24 months display edema of the extremities, torso, and face, fatty liver, sparse yellow hair, and receive adequate kilocalories but not enough high-quality proteins is called?
- A. Marasmus
- B. Kwashiorkor
- C. Anemia
- D. Noma
Correct answer: B
Rationale: Kwashiorkor is a form of severe malnutrition characterized by edema, fatty liver, and other symptoms, typically resulting from inadequate protein intake despite adequate calorie intake.
3. What physiologic role does calcium play in the body?
- A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
- B. Calcium homeostasis, structural integrity of heart muscle
- C. No known metabolic function, caries-preventing properties
- D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.
Correct answer: A
Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.
4. The stages of grieving identified by Elizabeth Kubler-Ross are:
- A. Numbness, anger, resolution and reorganization

5. Each of the following accurately describes features of MyPlate except one. Which one is the exception?
- A. MyPlate replaces the well-known food guide, MyPyramid.
- B. The interactive website is intended to help consumers apply personalized dietary guidance.
- C. Whereas MyPyramid was more specific in many areas, MyPlate provides more general information.
- D. Foods providing similar types of nutrients are grouped together and emphasize proportionality of food selections.
Correct answer: C
Rationale: The correct answer is C because MyPlate actually provides more specific guidance compared to MyPyramid. MyPlate was designed to simplify the dietary recommendations for consumers by focusing on a visual representation of a plate divided into food groups, making it easier to understand and apply. Choices A, B, and D accurately describe features of MyPlate: replacing MyPyramid, providing personalized dietary guidance through an interactive website, and grouping foods with similar nutrients while emphasizing proportionality of food selections.
