HESI PN Nutrition Practice Exam
1. What does the term 'essential nutrient' refer to?
- A. A nutrient that can be synthesized by the body.
- B. A nutrient that is required for proper body functioning.
- C. A nutrient that must be obtained from the diet because the body cannot produce it.
- D. A nutrient that can be stored in the body for long periods.
Correct answer: C
Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.
2. A child develops a strong dislike of noodle soup after consuming a bowl while sick with the flu. Her reaction is an example of a food-related ___.
- A. habit
- B. social interaction
- C. emotional turmoil
- D. negative association
Correct answer: D
Rationale: The correct answer is 'negative association.' A negative association occurs when a person develops a dislike for a food due to a past negative experience, such as getting sick after eating it. In this case, the child's dislike of noodle soup is specifically linked to the negative experience of consuming it while sick with the flu. Choices A, B, and C are incorrect because the situation described does not relate to habit formation, social interactions, or emotional turmoil, but rather to a learned aversion based on a specific negative event.
3. What is an important dietary consideration for a child with renal failure?
- A. Low-protein, low-sodium diet
- B. High-protein, high-sodium diet
- C. Increased calcium intake
- D. High-fiber diet
Correct answer: A
Rationale: A low-protein, low-sodium diet is crucial for a child with renal failure because it helps reduce the workload on the kidneys and minimize complications. High-protein and high-sodium diets can place excessive strain on the kidneys and worsen the condition. Increased calcium intake is not typically a primary consideration for renal failure in children. While a high-fiber diet can be beneficial for overall health, it is not a specific priority for managing renal failure in children.
4. What is one benefit of using controls in an experiment?
- A. The size of the groups does not matter.
- B. The subjects are unaware of the experiment's details.
- C. The subjects who are treated are balanced against the placebos.
- D. The subjects are similar in all respects except for the treatment being tested.
Correct answer: D
Rationale: The correct answer is D. Controls in an experiment ensure that the subjects are similar in all respects except for the treatment being tested. This allows for a fair comparison between the treatment group and the control group. Choice A is incorrect because the size of the groups is not the primary benefit of using controls. Choice B is incorrect as blinding, not controls, refers to subjects not knowing about the experiment. Choice C is incorrect as it pertains more to randomization than the use of controls.
5. Which nutrient is classified as a micronutrient?
- A. minerals
- B. proteins
- C. alcohols
- D. carbohydrates
Correct answer: A
Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.
