1. 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.

2. Which parental statement indicates correct understanding of information presented regarding the prevention of iron deficiency anemia in infants?

• A. "We will add green leafy vegetables to our child’s low-iron formula."
• B. "We will discontinue the use of vitamin C supplements by 6 months of age."
• C. "We will begin an iron-fortified infant cereal at 4 to 6 months of age."
• D. "We will introduce cow’s milk by 6 months of age."

Correct answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.

3. Which is described as an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid?

• A. Cyst
• B. Papule
• C. Pustule
• D. Vesicle

Correct answer: D

Rationale: A vesicle is an elevated, circumscribed lesion filled with serous fluid, typically less than 1 cm in diameter.

4. What findings on physical assessment of a neonate would indicate the need for further evaluation?

• A. Nystagmus
• B. Epstein pearls
• C. Low-set ears
• D. Positive Babinski reflex

Correct answer: C

Rationale: Low-set ears in a neonate suggest major abnormalities and should prompt further evaluation. The correct alignment of the top of the pinnae of the ear with the outer canthus of the eye is crucial. Nystagmus, an involuntary eye movement, is common in newborns and often resolves on its own. Epstein pearls, small cysts on the hard palate, are insignificant and disappear over time. A positive Babinski reflex is normal in infants up to 1 year of age. Therefore, the presence of low-set ears is the most concerning finding that requires immediate attention.

5. What is the recommended position for a child with epiglottitis to ease breathing?

• A. Supine
• B. Prone
• C. Tripod
• D. Semi-Fowler’s

Correct answer: C

Rationale: The correct answer is C, 'Tripod.' In children with epiglottitis, the tripod position is recommended to help open the airway and ease breathing. This position involves the child sitting upright, leaning forward, and supporting themselves with their hands on their knees or another surface. This posture helps improve air entry into the lungs by maximizing the space for breathing. Choices A (Supine), B (Prone), and D (Semi-Fowler’s) are incorrect. Placing a child with epiglottitis in the supine position may further obstruct the airway, while the prone position and semi-Fowler’s position do not facilitate optimal air exchange in these cases.
