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 common sign of congenital hip dysplasia in infants?

• A. Symmetrical hip movement
• B. Limited range of motion in the hip
• C. Swelling of the knees
• D. Dislocated patella

Correct answer: B

Rationale: Limited range of motion in the hip, often noted as a limitation in abduction, is a common sign of congenital hip dysplasia. This limitation is due to the abnormal development of the hip joint, affecting its movement. Symmetrical hip movement (Choice A) is not a characteristic sign of congenital hip dysplasia. Swelling of the knees (Choice C) is not typically associated with this condition. Dislocated patella (Choice D) refers to a different anatomical structure and is not a common sign of congenital hip dysplasia.

3. What is an important aspect of care for a child with congenital adrenal hyperplasia?

• A. Monitoring electrolyte levels
• B. Restricting physical activity
• C. Administering high doses of vitamin A
• D. Providing a high-protein diet

Correct answer: A

Rationale: The correct answer is A: Monitoring electrolyte levels. In the management of congenital adrenal hyperplasia, it is crucial to monitor electrolyte levels to prevent imbalances and related complications. Restricting physical activity (choice B) is not a typical aspect of care for this condition. Administering high doses of vitamin A (choice C) is not a standard treatment for congenital adrenal hyperplasia and can be harmful in excess. Providing a high-protein diet (choice D) may be beneficial for some conditions but is not a specific requirement for managing congenital adrenal hyperplasia.

4. What is a crucial aspect of managing a child with cystic fibrosis?

• A. High-sugar diet
• B. Daily chest physiotherapy
• C. Frequent use of antacids
• D. Limiting fluid intake

Correct answer: B

Rationale: Daily chest physiotherapy is crucial in managing cystic fibrosis as it helps clear mucus from the lungs, improves respiratory function, and reduces the risk of lung infections. High-sugar diets are not recommended for individuals with cystic fibrosis as they can contribute to mucus production, exacerbating respiratory issues. Frequent use of antacids is not a primary treatment for cystic fibrosis, as it does not address the underlying lung issues. Limiting fluid intake is not typically advised for individuals with cystic fibrosis, as adequate hydration is essential for maintaining lung function and thinning mucus secretions.

5. How should a healthcare professional approach the care of a child with a newly diagnosed type 1 diabetes?

• A. Emphasize the importance of blood glucose monitoring
• B. Avoid insulin therapy
• C. Encourage a high-carbohydrate diet
• D. Recommend alternative therapies only

Correct answer: A

Rationale: Corrected Rationale: Emphasizing the importance of blood glucose monitoring is crucial for managing type 1 diabetes effectively. Monitoring blood glucose levels helps in maintaining optimal control of the condition, adjusting treatment plans as necessary, and preventing complications. Choice B is incorrect because insulin therapy is the mainstay treatment for type 1 diabetes to regulate blood sugar levels. Choice C is incorrect because while diet is important, encouraging a high-carbohydrate diet can lead to fluctuations in blood sugar levels. Choice D is incorrect because alternative therapies should not replace standard medical treatment like insulin therapy in type 1 diabetes management.
