Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left to right shunt

Correct answer: B

Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. The caregiver is caring for a 3-year-old child with a diagnosis of gastroenteritis. The child has had several episodes of vomiting and diarrhea over the past 24 hours. What is the caregiver's priority assessment?

• A. Monitor the child's weight
• B. Assess the child's hydration status
• C. Evaluate the child's nutritional intake
• D. Check the child's temperature

Correct answer: B

Rationale: The correct answer is B: Assess the child's hydration status. In children with gastroenteritis, assessing hydration status is crucial as they are at risk of dehydration due to vomiting and diarrhea. Monitoring hydration helps prevent complications and guides appropriate interventions to maintain the child's fluid balance. Monitoring the child's weight (Choice A) is not the priority in this situation compared to assessing hydration status. Evaluating nutritional intake (Choice C) is important but not the priority when the child is at risk of dehydration. Checking the child's temperature (Choice D) is relevant but not the priority over assessing hydration status in a child with gastroenteritis.

3. A two-year-old child with heart failure is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.

4. What is the most important information for the PN to reinforce with the parents when caring for a child diagnosed with acute rheumatic fever?

• A. Complete the full course of prescribed antibiotics.
• B. Ensure the child gets plenty of physical exercise.
• C. Keep the child on a low-sodium diet.
• D. Administer prescribed pain medications as needed.

Correct answer: A

Rationale: Completing the full course of antibiotics is crucial in the management of acute rheumatic fever as it helps prevent recurrence and complications. Antibiotics are essential in eradicating the underlying infection that triggers the autoimmune response leading to rheumatic fever. Reinforcing the importance of completing the prescribed antibiotic regimen is vital to ensure the child's recovery and prevent further health issues. Choices B, C, and D are not as critical as completing the antibiotic treatment. While physical exercise, a low-sodium diet, and pain management are important aspects of overall health, they are not the primary focus when managing acute rheumatic fever.

5. While auscultating the lung sounds of a 5-year-old Chinese boy who recently completed antibiotic therapy for pneumonia, the nurse notices symmetrical, round, bruise-like blemishes on his chest. What action is best for the nurse to take?

• A. Identify the antibiotics used for treating the pneumonia.
• B. Inquire about the use of alternative treatment methods.
• C. Ask the parents if the child has been in a recent accident.
• D. Report suspected child abuse to the authorities.

Correct answer: B

Rationale: Inquiring about the use of alternative treatment methods is essential to understand cultural practices and provide holistic care. It allows the nurse to gather more information about the blemishes and potentially uncover traditional or alternative healing approaches that the family may have used. This approach demonstrates cultural sensitivity and a comprehensive assessment before making assumptions or taking further actions. Identifying the antibiotics used for treating pneumonia (Choice A) is not immediately necessary in this context as the focus is on the blemishes. Asking about a recent accident (Choice C) assumes a traumatic cause without evidence. Reporting suspected child abuse (Choice D) is premature without further assessment or evidence of abuse.
