1. 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.

2. What is a common sign of dehydration in infants?

• A. Decreased urination
• B. Dry mouth and lips
• C. Increased appetite
• D. Normal skin turgor

Correct answer: B

Rationale: Dry mouth and lips are common signs of dehydration in infants. When an infant is dehydrated, the body conserves water, resulting in less urine production and concentrated urine. This leads to decreased frequency of urination rather than frequent urination, making choice A incorrect. Choice C, increased appetite, is not typically associated with dehydration in infants but rather with normal growth and development. Normal skin turgor, as mentioned in choice D, is a sign of hydration and not dehydration, making it an incorrect choice. Therefore, the correct answer is B, dry mouth and lips, which indicate a need for fluid replacement.

3. What is a common early sign of type 1 diabetes in children?

• A. Excessive thirst and frequent urination
• B. Severe abdominal pain
• C. Frequent headaches
• D. Sudden weight gain

Correct answer: A

Rationale: Excessive thirst and frequent urination are common early signs of type 1 diabetes in children. These symptoms occur due to high blood glucose levels, leading to increased thirst and urination. Severe abdominal pain (choice B) is not typically associated with type 1 diabetes. Although frequent headaches (choice C) can occur in some cases, they are not as specific to type 1 diabetes as excessive thirst and frequent urination. Sudden weight gain (choice D) is not a common early sign of type 1 diabetes; in fact, unexplained weight loss is more characteristic of the condition.

4. What is the appropriate intervention for a child with an undescended testicle?

• A. Wait until puberty
• B. Perform an orchidopexy
• C. Administer hormone therapy
• D. Increase physical activity

Correct answer: B

Rationale: The appropriate intervention for a child with an undescended testicle is to perform an orchidopexy. This surgical procedure is recommended if the testicle has not descended naturally within the first year of life. Waiting until puberty is not advised as early intervention is crucial for optimal outcomes. Administering hormone therapy is not the first-line treatment for an undescended testicle and is typically not recommended. Increasing physical activity does not address the underlying issue of an undescended testicle and is not a suitable intervention.

5. What is a common early sign of RSV (respiratory syncytial virus) in infants?

• A. High fever
• B. Nasal congestion
• C. Rash
• D. Jaundice

Correct answer: B

Rationale: Nasal congestion is a common early sign of RSV in infants, often accompanied by cough and wheezing. High fever, rash, and jaundice are not typically associated with RSV. While RSV can lead to fever, it is usually not one of the earliest signs. Rash and jaundice are unrelated to RSV symptoms.
