Nursing Elites

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. In teaching the parent of a newly diagnosed 2-year-old child with pyelonephritis related to vesicoureteral reflux (VUR), the nurse should include which information?

• A. Limit fluids to reduce reflux.
• B. Give cranberry juice twice a day.
• C. Have siblings examined for VUR.
• D. Surgery is indicated to reverse scarring.

Correct answer: C

Rationale: Siblings should be examined for VUR as it can run in families, and early detection can prevent complications. Limiting fluids is not advisable, and cranberry juice is not effective in preventing VUR. Surgery is usually not indicated for scarring reversal.

3. What is the most critical physiologic change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.

4. A child with acetylsalicylic acid (aspirin) poisoning is being admitted to the emergency department. What early clinical manifestation does the nurse expect to assess on this child?

• A. Hematemesis
• B. Hematochezia
• C. Hyperglycemia
• D. Hyperventilation

Correct answer: D

Rationale: Early signs of aspirin poisoning include hyperventilation due to the stimulation of the respiratory center and the resultant respiratory alkalosis. Hematemesis, hematochezia, and hyperglycemia can occur later in the poisoning process or may not be directly related to aspirin toxicity.

5. The nurse determines that a child's intravenous infusion has infiltrated. The infused solution is a vesicant. What is the most appropriate nursing action?

• A. Stop the infusion and apply ice.
• B. End the infusion and notify the practitioner.
• C. Slow the infusion rate and notify the practitioner.
• D. Discontinue the infusion and apply warm compresses.

Correct answer: B

Rationale: If a vesicant solution infiltrates, stopping the infusion immediately and notifying the practitioner is critical to prevent tissue damage. Cold or warm compresses should only be applied following specific medical advice based on the vesicant involved.
