HESI PN Nutrition Practice Exam
1. You have been asked to help a top nutrition researcher conduct human experiments on vitamin C. As the subjects walk into the laboratory, you distribute all the vitamin C pill bottles to the girls and all the placebo pill bottles to the boys. What should you have done?
- A. Giving all the boys the vitamin C and the girls the placebo, and telling them what they were getting.
- B. Distributing the bottles randomly, randomizing the subjects, and telling them what they were getting.
- C. Telling the subjects which group they were in, but preventing yourself from knowing the contents of the pill bottles.
- D. Preventing yourself from knowing what is in the pill bottles, and distributing the bottles randomly to the subjects.
Correct answer: D
Rationale: The correct approach in a scientific experiment is to prevent yourself from knowing the contents of the pill bottles and distribute them randomly to the subjects. This randomization helps to avoid bias and ensures that the results are not influenced by preconceived notions. Option A is incorrect because it introduces gender bias by assigning pills based on gender. Option B is incorrect as it mentions telling the subjects what they are getting, which could lead to placebo effects. Option C is incorrect as it suggests disclosing group information to the subjects, which can also introduce bias.
2. How should a healthcare provider address the nutritional needs of a child with chronic kidney disease?
- A. Increase protein intake
- B. Reduce sodium and phosphorus intake
- C. Promote a high-fat diet
- D. Encourage frequent sugary snacks
Correct answer: B
Rationale: Reducing sodium and phosphorus intake is crucial in managing chronic kidney disease in children because it helps prevent complications such as electrolyte imbalances and bone problems. High protein intake can actually be harmful to the kidneys in this condition as it can lead to increased waste production. A high-fat diet is not recommended as it can contribute to heart and blood vessel problems. Encouraging frequent sugary snacks can lead to further complications like obesity and diabetes, which are not beneficial for a child with chronic kidney disease.
3. Your friend Carrie took a daily supplement of vitamin C and tells you that she feels a lot better. Her statement to you is best described as what?
- A. an anecdote
- B. theory
- C. interpretation
- D. conclusion
Correct answer: A
Rationale: The correct answer is A, 'an anecdote.' An anecdote is a personal account or experience, not necessarily backed by scientific evidence. In this case, Carrie's statement about feeling better after taking vitamin C is based on her personal experience and does not constitute scientific evidence or a generalizable conclusion. Choice B, 'theory,' would imply a systematic explanation based on scientific evidence, which is not the case here. Choice C, 'interpretation,' typically involves explaining or understanding something based on available information, not a personal account. Choice D, 'conclusion,' would be a general statement derived from specific information or facts, which is not applicable in this context.
4. What role do fats play in the human body?
- A. They provide a concentrated source of energy.
- B. They are the building blocks of enzymes and hormones.
- C. They are essential for brain function and development.
- D. They aid in the digestion of food.
Correct answer: D
Rationale: Fats play various essential roles in the human body, one of which is aiding in the digestion of food. While fats do provide a concentrated source of energy, the primary source is carbohydrates. Proteins are the building blocks of enzymes and hormones, not fats. Essential fatty acids found in fats are vital for brain function and development, but this is not the primary role of fats in the body.
5. What is an essential part of care for a child with asthma during an acute episode?
- A. Administer a bronchodilator
- B. Provide high doses of steroids
- C. Increase fluid intake
- D. Restrict all physical activity
Correct answer: A
Rationale: Administering a bronchodilator is an essential part of caring for a child with asthma during an acute episode because it helps to open airways and relieve acute asthma symptoms effectively. Providing high doses of steroids (Choice B) is typically done in severe cases or when other treatments fail. Increasing fluid intake (Choice C) can be beneficial to prevent dehydration, but it is not the primary intervention during an acute asthma episode. Restricting all physical activity (Choice D) is not recommended as some physical activity may help improve lung function and overall well-being.
