HESI PN Nutrition Practice Exam
1. What is a common sign of an allergic reaction in children?
- A. Persistent cough
- B. Skin rash or hives
- C. Increased appetite
- D. Low-grade fever
Correct answer: B
Rationale: Skin rash or hives are common signs of an allergic reaction in children, often following exposure to allergens. While a persistent cough can occur in some cases, it is not typically a primary sign of an allergic reaction. Increased appetite is unrelated to allergic reactions. A low-grade fever is not a common sign of an allergic reaction but can be present in other conditions like infections.
2. How should a healthcare provider address a child's nutritional needs with a lactose intolerance diagnosis?
- A. Recommend lactose-free dairy products
- B. Increase dairy intake
- C. Encourage high-fiber diet
- D. Use oral probiotics only
Correct answer: A
Rationale: In managing lactose intolerance in a child, recommending lactose-free dairy products is crucial. These products help address the child's nutritional needs without causing symptoms related to lactose consumption. Choice B is incorrect because increasing dairy intake would exacerbate symptoms in a lactose-intolerant individual as they cannot digest lactose properly. Choice C, encouraging a high-fiber diet, is not directly related to managing lactose intolerance and may not address the primary issue of lactose malabsorption. Choice D, using oral probiotics only, may not be sufficient to address the child's nutritional needs in case of lactose intolerance as the main concern is avoiding lactose-containing products.
3. 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.
4. What is a key dietary consideration for a child with phenylketonuria (PKU)?
- A. High-fiber diet
- B. Low-phenylalanine diet
- C. Increased dairy intake
- D. High-sodium diet
Correct answer: B
Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.
5. Which medication is typically used for long-term control of asthma?
- A. Albuterol
- B. Theophylline
- C. Ipratropium
- D. Prednisone
Correct answer: B
Rationale: The correct answer is B, Theophylline. Theophylline is commonly used for long-term control of asthma by relaxing the muscles around the airways to keep them open, making breathing easier. Albuterol (choice A) is a short-acting bronchodilator for quick relief of asthma symptoms, not for long-term control. Ipratropium (choice C) is another short-acting bronchodilator that helps open the airways but is not typically used for long-term control. Prednisone (choice D) is a corticosteroid usually used for short periods to control asthma exacerbations or flare-ups, not as a long-term control medication.
