HESI PN Nutrition Practice Exam
1. How should a healthcare provider address a child's concerns about a new medical diagnosis?
- A. Provide clear and age-appropriate information
- B. Avoid discussing the diagnosis
- C. Refer to a specialist immediately
- D. Suggest seeking alternative therapies
Correct answer: A
Rationale: Correct answer: Providing clear and age-appropriate information is crucial when addressing a child's concerns about a new medical diagnosis. Children often feel anxious and confused when faced with health issues, so offering them information in a way they can understand helps alleviate their fears and empowers them to cope better. Choice B is incorrect because avoiding discussing the diagnosis can lead to increased anxiety and uncertainty in the child. Choice C is incorrect as referring to a specialist immediately may not be necessary at the initial stage of addressing the child's concerns. Choice D is incorrect as suggesting alternative therapies without providing proper information about the medical diagnosis may not be suitable or effective.
2. What is the term for the study of how diet affects gene expression?
- A. Epigenetics
- B. Nutrigenomics
- C. Genomics
- D. Genetics
Correct answer: B
Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.
3. What should be monitored closely in a child receiving chemotherapy?
- A. Blood glucose levels
- B. White blood cell count
- C. Blood pressure
- D. Heart rate
Correct answer: B
Rationale: The correct answer is B: White blood cell count. During chemotherapy, it is crucial to monitor the white blood cell count closely to detect potential neutropenia (low white blood cell count) and the associated risk of infections. Monitoring blood glucose levels (Choice A) is important for diabetic management and not directly related to chemotherapy. Blood pressure (Choice C) and heart rate (Choice D) are essential vital signs to monitor but are not the primary focus when monitoring a child receiving chemotherapy.
4. Why is peer review important in scientific research?
- A. To expedite publication of results.
- B. To facilitate the replication of studies.
- C. To verify the accuracy and validity of research findings.
- D. To enhance the credibility of the research.
Correct answer: C
Rationale: Peer review is crucial in scientific research to verify the accuracy and validity of research findings. By subjecting research papers to evaluation by experts in the field, peer review ensures that the study's methods, results, and conclusions are robust and reliable. This process helps to maintain high standards of quality in scientific publications, providing credibility to the research. Choices A and D are incorrect because the primary purpose of peer review is not to expedite publication or solely enhance credibility; its core function is to validate the research's accuracy and validity. Choice B, while beneficial, is not the primary reason for peer review; replication is a byproduct of the rigorous evaluation of research methods and findings.
5. What is a key sign of meningitis in an infant?
- A. Increased appetite
- B. Bulging fontanel
- C. Decreased respiratory rate
- D. Elevated blood pressure
Correct answer: B
Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.
