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. When describing play by the school-aged child to a group of nursing students, the instructor would emphasize the need for which of the following?

• A. Recreation
• B. Ritualism
• C. Physical activity
• D. Rules

Correct answer: D

Rationale: The correct answer is D: Rules. When discussing play in school-aged children, rules are essential as they help in structuring games and social interactions. Rules provide a framework for play, ensuring fairness and cooperation among children. Choice A, recreation, is too broad and doesn't specifically address the importance of rules in play. Choice B, ritualism, is unrelated to the concept of play in school-aged children. Choice C, physical activity, is important for overall health but doesn't capture the specific aspect of rules that are crucial in the play of school-aged children.

3. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

4. An infant is born with a gastroschisis. Care preoperatively should include which priority intervention?

• A. Prone position
• B. Sterile water feedings
• C. Monitoring serum laboratory electrolytes
• D. Covering the defect with a sterile bowel bag

Correct answer: D

Rationale: The correct priority intervention for an infant with gastroschisis is to cover the exposed abdominal contents with a sterile bowel bag. This action helps protect the intestines from injury, contamination, and dehydration before surgical repair. Choice A, placing the infant in the prone position, is not appropriate as it does not address the immediate need to protect the exposed intestines. Choice B, sterile water feedings, and Choice C, monitoring serum laboratory electrolytes, are not the priority interventions for this condition. Sterile water feedings may not provide the necessary protection for the exposed intestines, and monitoring electrolytes, while important, is secondary to the immediate need for protection and hydration of the exposed abdominal contents.

5. A sixteen-year-old boy is diagnosed with osteosarcoma. What information should the nurse know regarding the treatment plan?

• A. Amputation of the affected extremity is rarely necessary.
• B. Intensive radiation is the primary treatment modality.
• C. Treatment usually consists of surgery and chemotherapy.
• D. Bone marrow transplantation is the preferred option for long-term survival.

Correct answer: C

Rationale: Osteosarcoma is typically treated with a combination of surgery and chemotherapy. This approach aims to remove the tumor and reduce the risk of metastasis. Amputation of the affected extremity may be necessary in some cases to ensure complete removal of the tumor. Intensive radiation is not the primary treatment for osteosarcoma, and bone marrow transplantation is not the standard treatment for this type of cancer.
