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. Which of the following is a common complication of an untreated inguinal hernia in children?

• A. Gastroenteritis
• B. Strangulation of the hernia
• C. Chronic cough
• D. Epistaxis

Correct answer: B

Rationale: The correct answer is B: Strangulation of the hernia. Untreated inguinal hernias in children can lead to strangulation, which can result in bowel obstruction and ischemia. This is a serious complication that requires prompt medical attention. Choices A, C, and D are incorrect. Gastroenteritis is a gastrointestinal infection that is not directly related to untreated inguinal hernias. Chronic cough is not typically associated with this condition. Epistaxis refers to nosebleeds, which are not a common complication of untreated inguinal hernias in children.

3. What is a common clinical manifestation of Kawasaki disease?

• A. Severe headaches
• B. High fever lasting more than 5 days
• C. Chronic cough
• D. Severe abdominal pain

Correct answer: B

Rationale: A high fever lasting more than 5 days is a common clinical manifestation of Kawasaki disease. This fever is often accompanied by other symptoms such as rash and conjunctivitis. Severe headaches (Choice A), chronic cough (Choice C), and severe abdominal pain (Choice D) are not typically associated with Kawasaki disease, making them incorrect choices.

4. What is the primary source of energy for the brain and nervous system?

• A. Protein
• B. Fat
• C. Carbohydrate
• D. Glucose

Correct answer: D

Rationale: Glucose is the correct answer as it is the primary source of energy for the brain and nervous system. The brain relies heavily on glucose to function optimally. While protein and fat play essential roles in the body, they are not the primary sources of energy for the brain and nervous system. Carbohydrates, on the other hand, are broken down into glucose, which is then used as fuel by the brain and nervous system.

5. What is a key aspect of care for a child with an indwelling urinary catheter?

• A. Increase fluid intake
• B. Monitor for signs of infection
• C. Restrict mobility
• D. Administer daily antibiotics

Correct answer: B

Rationale: Monitoring for signs of infection is crucial when caring for a child with an indwelling urinary catheter. This is because catheter-associated urinary tract infections are common in such cases. Increasing fluid intake can be beneficial, but monitoring for infection takes precedence as it is crucial to prevent complications. Restricting mobility is not a key aspect of care for a child with an indwelling urinary catheter unless specifically advised by a healthcare provider. Administering daily antibiotics without proper assessment and indication can lead to antibiotic resistance and is not a standard practice in caring for a child with an indwelling urinary catheter.
