1. 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.

2. What is a primary concern for a child with a new diagnosis of diabetes mellitus?

• A. Increased growth rate
• B. Risk of hyperglycemia
• C. Risk of dehydration
• D. Improved appetite

Correct answer: B

Rationale: The correct answer is B: Risk of hyperglycemia. When a child is newly diagnosed with diabetes mellitus, one of the primary concerns is the risk of hyperglycemia, which refers to high blood glucose levels. Hyperglycemia can lead to various complications if not managed properly, making it crucial to stabilize blood glucose levels. Choices A, C, and D are incorrect because increased growth rate, risk of dehydration, and improved appetite are not primary concerns specifically associated with a new diagnosis of diabetes mellitus.

3. 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.

4. What should be assessed in an infant diagnosed with hypertrophic pyloric stenosis?

• A. Diarrhea after each feeding
• B. Gastric pain and vigorous crying
• C. Poor appetite due to poor sucking reflex
• D. An olive-shaped mass right of the midline

Correct answer: D

Rationale: In hypertrophic pyloric stenosis, an olive-shaped mass can often be palpated in the infant's abdomen, which is a hallmark sign of this condition. This mass is located in the right upper quadrant of the abdomen, right of the midline. Choices A, B, and C are incorrect because while infants with hypertrophic pyloric stenosis may experience vomiting (not diarrhea), gastric pain, and irritability, and have feeding difficulties, the key assessment finding specific to this condition is the palpable olive-shaped mass in the abdomen.

5. What is a common treatment for a child with a urinary tract infection (UTI)?

• A. Intravenous antibiotics
• B. Oral antibiotics
• C. Increased fluid intake only
• D. Topical antibiotics

Correct answer: B

Rationale: Oral antibiotics are the correct choice for treating a child with a urinary tract infection (UTI). They are often prescribed to effectively address the infection and alleviate symptoms. Intravenous antibiotics (Choice A) are usually reserved for severe cases where oral antibiotics are not feasible or effective. Increased fluid intake (Choice C) can help in flushing out bacteria but is not a standalone treatment for UTIs. Topical antibiotics (Choice D) are not typically used to treat UTIs as they are more suited for skin infections.
