1. What is the first sign of puberty in boys?

• A. Enlargement of testes
• B. Decreased levels of testosterone
• C. Voice deepening
• D. Pubic hair

Correct answer: A

Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.

2. In pediatric patients, what is the primary concern with untreated vesicoureteral reflux (VUR)?

• A. Recurrent UTIs
• B. Chronic renal failure
• C. Hypertension
• D. Bladder dysfunction

Correct answer: B

Rationale: The primary concern with untreated vesicoureteral reflux (VUR) in pediatric patients is chronic renal failure. Untreated VUR can lead to this complication due to recurrent urinary tract infections and kidney damage. While recurrent UTIs (Choice A) are a common consequence of VUR, the ultimate worry is the development of chronic renal failure. Hypertension (Choice C) may occur as a result of renal damage but is not the primary concern. Bladder dysfunction (Choice D) is not the most significant consequence of untreated VUR in terms of long-term outcomes compared to chronic renal failure.

3. When should a child receive the first dose of the hepatitis B virus (HBV) vaccine if the mother is hepatitis B surface antigen (HBsAg) negative?

• A. 2 months of age, before hospital discharge.
• B. Birth before discharge from the hospital.
• C. 6 months of age, at the third well-child visit.
• D. No time (this vaccine is not currently recommended).

Correct answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.

4. What interventions should be implemented to maintain the skin integrity of a preterm infant born at 30 weeks?

• A. Avoid cleaning the skin
• B. Bathe the infant with sterile water
• C. Cleanse the skin with a gentle alkaline-based soap and water
• D. Thoroughly rinse the skin with plain water after bathing

Correct answer: B

Rationale: The correct intervention to maintain the skin integrity of a preterm infant born at 30 weeks is to bathe the infant with sterile water. Bathing with sterile water or a neutral pH solution is recommended to protect the delicate skin of preterm infants, which is more permeable and prone to damage. Choices A, C, and D are incorrect as avoiding cleaning the skin may lead to hygiene issues, cleansing with alkaline-based soap can be harsh on the delicate skin, and thoroughly rinsing with plain water after bathing may not be as gentle and protective for preterm infants.

5. What are classified as hydrocarbon poisons?

• A. All below
• B. Gasoline
• C. Turpentine
• D. Lighter fluid

Correct answer: A

Rationale: Hydrocarbon poisons include substances like gasoline, turpentine, and lighter fluid, which are typically liquids derived from petroleum. Bleach is a corrosive substance, not a hydrocarbon.
