Nursing Elites

1. A child is admitted with renal failure. Which of these findings should the nurse expect?

• A. Decreased BUN
• B. Azotemia and oliguria
• C. Increased glomerular filtration rate (GFR)
• D. Polyuria and elevated creatinine clearance

Correct answer: B

Rationale: Azotemia (elevated BUN and creatinine) and oliguria (reduced urine output) are classic signs of renal failure, indicating impaired kidney function. In renal failure, the kidneys are unable to effectively filter waste products, leading to an increase in BUN and creatinine levels in the blood. Additionally, oliguria occurs due to decreased kidney function. Increased GFR (Choice C) is not expected in renal failure as it signifies improved kidney function, which is not the case in renal failure. Polyuria and elevated creatinine clearance (Choice D) are not typical findings in renal failure. Polyuria is more commonly associated with conditions like diabetes insipidus, while elevated creatinine clearance would indicate increased kidney function, which is contrary to the impaired function seen in renal failure.

2. In general, how much is a child that was 10 pounds at birth expected to weigh at 6 months old?

• A. Double = 20 lbs
• B.
• C.
• D.

Correct answer: A

Rationale: The correct answer is A. A child is expected to double their birth weight by 6 months. This is a common guideline used to monitor healthy growth and development in infants. Choices B, C, and D are incorrect as they do not provide the expected weight based on the given information.

3. Which heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?

• A. S1 and S2
• B. S3 and S4
• C. Murmur
• D. Physiologic splitting

Correct answer: C

Rationale: A murmur is produced by turbulent blood flow within the heart or major arteries, resulting in audible vibrations.

4. 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.

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.
