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. The nurse is teaching a nursing student about standard precautions. Which statement made by the student indicates a need for further teaching?

• A. I will use precautions when I give an infant oral care
• B. I will use precautions when I change an infant's diaper
• C. I will use precautions when I come in contact with blood and body fluids
• D. I will use precautions when administering oral medications to a school-age child

Correct answer: D

Rationale: Standard precautions are necessary when dealing with blood, body fluids, and potentially infectious materials. They are not required for routine administration of oral medications unless there is a potential exposure risk.

3. What is a primary consideration for complications when planning nursing care for an infant with Meconium aspiration syndrome?

• A. Hypoglycemia
• B. Bowel obstruction
• C. Airway obstruction
• D. Carbon dioxide retention

Correct answer: C

Rationale: The correct answer is C: Airway obstruction. When planning nursing care for an infant with Meconium aspiration syndrome, a primary consideration for complications is the potential of airway obstruction. After the passage of meconium into the amniotic fluid, the infant may inhale or swallow the fluid, leading to meconium aspiration into the lower airways and causing a partial airway obstruction. This can result in respiratory distress and hypoxemia. Hypoglycemia (choice A) is a metabolic condition unrelated to meconium aspiration. Bowel obstruction (choice B) with meconium may indicate other conditions like cystic fibrosis or Hirschsprung disease, not directly related to meconium aspiration syndrome. Carbon dioxide retention (choice D) is not a primary consideration in meconium aspiration syndrome; instead, the focus is on addressing the airway obstruction and potential respiratory compromise.

4. What is the most common cause of acute kidney injury in children?

• A. Dehydration
• B. Glomerulonephritis
• C. Hemolytic uremic syndrome
• D. Sepsis

Correct answer: C

Rationale: Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. While dehydration can lead to prerenal acute kidney injury, it is not the most common cause in children. Glomerulonephritis is a common cause of chronic kidney disease but not typically the most common cause of acute kidney injury in children. Sepsis can lead to acute kidney injury, but in children, hemolytic uremic syndrome is more prevalent.

5. At what stage can infants raise their heads and gain control of their trunks before walking due to which directional pattern of development?

• A. Cephalocaudal
• B. Anterior to posterior
• C. Proximodistal
• D. Normal growth curve charts

Correct answer: A

Rationale: The correct answer is A: Cephalocaudal. The cephalocaudal pattern of development means that growth and motor control proceed from the head downward through the body. This explains why infants can raise their heads before they can sit and gain control of their trunks before walking. Choices B, C, and D are incorrect. Anterior to posterior refers to development from the front to the back, while proximodistal refers to development from the center of the body outward. Normal growth curve charts are used to track physical growth over time and are not directly related to the directional pattern of development in infants.
