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. 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.

3. What nursing consideration is most important when caring for a child with end-stage renal disease (ESRD)?

• A. Children with ESRD usually adapt well to minor inconveniences of treatment.
• B. Children with ESRD require extensive support until they outgrow the condition.
• C. Multiple stresses are placed on children with ESRD and their families until the illness is cured.
• D. Multiple stresses are placed on children with ESRD and their families because children's lives are maintained by drugs and artificial means.

Correct answer: D

Rationale: ESRD places significant stress on both the child and the family due to the ongoing need for dialysis, medications, and lifestyle restrictions, making it important for healthcare providers to offer extensive support and resources to manage these challenges.

4. Several types of long-term central venous access devices are used. What is a benefit of using an implanted port (e.g., Port-a-Cath)?

• A. You do not need to pierce the skin for access.
• B. It is easy to use for self-administered infusions.
• C. The patient does not need to limit regular physical activity, including swimming.
• D. The catheter cannot dislodge from the port even if the child plays with the port site.

Correct answer: C

Rationale: Implanted ports like the Port-a-Cath are fully implanted under the skin, allowing the child to maintain regular physical activities, including swimming, without the risk of dislodging the catheter. Piercing the skin is still required for access, and self-administration is more complex.

5. What amount of fluid loss occurs with moderate dehydration?

• A. <50 ml/kg
• B. 50 to 90 ml/kg
• C. <5% total body weight
• D. >15% total body weight

Correct answer: B

Rationale: Moderate dehydration is typically defined as a loss of 50 to 90 mL/kg of body weight. This amount reflects significant fluid loss that requires medical attention but is not yet severe.
