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. Which data should be included in a health history?

• A. Review of systems
• B. Physical assessment
• C. Growth measurements
• D. Record of vital signs

Correct answer: A

Rationale: The review of systems is a critical part of a health history, helping to identify any symptoms or conditions that need further evaluation.

3. Which best describes signs and symptoms as part of a nursing diagnosis?

• A. Description of potential risk factors
• B. Identification of actual health problems
• C. Human response to state of illness or health
• D. Cues and clusters derived from patient assessment

Correct answer: D

Rationale: Signs and symptoms are cues and clusters derived from patient assessments that are used to form a nursing diagnosis, guiding the development of a care plan.

4. Which laboratory value at the time of diagnosis should the nurse anticipate would determine the worst prognosis for a child with leukemia?

• A. Slow response to chemotherapy
• B. Platelets of 150,000/mcL
• C. Leukocytes less than 10,000/mcL
• D. Leukocytes of 275,000/mcL

Correct answer: D

Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.

5. What is the primary consideration of susceptibility to infections in neonates?

• A. Increased humoral immunity
• B. Overwhelming anti-inflammatory response
• C. Diminished nonspecific and specific immunity
• D. Excessive levels of immunoglobulin A and immunoglobulin M

Correct answer: C

Rationale: The primary consideration of susceptibility to infections in neonates is their diminished nonspecific and specific immunity. Neonates lack the ability to mount a robust immune response, making them vulnerable to infections. Choice A is incorrect because neonates do not have increased humoral immunity; rather, their humoral immunity is diminished. Choice B is incorrect as neonates do not have an overwhelming anti-inflammatory response; instead, their immune responses are generally weakened. Choice D is incorrect because neonates have diminished or absent levels of immunoglobulin A and immunoglobulin M, contributing to their susceptibility to infections.
