HESI Pediatric Practice Exam
1. A 2-week-old female infant is hospitalized for the surgical repair of an umbilical hernia. After returning to the postoperative neonatal unit, her RR and HR have increased during the last hour. Which intervention should the nurse implement?
- A. Notify the healthcare provider of these findings
- B. Administer a PRN analgesic as prescribed
- C. Document the findings in the infant's medical record
- D. Comfort the infant by swaddling and gently rocking
Correct answer: A
Rationale: In a postoperative neonatal setting, an increase in respiratory rate (RR) and heart rate (HR) in an infant could indicate pain or distress. It is crucial for the nurse to notify the healthcare provider promptly to assess the infant's condition and provide appropriate interventions. Prompt communication with the healthcare provider ensures timely evaluation and management of the infant's discomfort or distress, promoting optimal postoperative recovery and comfort. Administering analgesics without healthcare provider assessment could mask underlying issues, documenting findings alone does not address the immediate need for intervention, and comforting may not resolve the underlying cause of increased RR and HR.
2. A child with sickle cell anemia is being treated for a vaso-occlusive crisis. Which intervention should the practical nurse (PN) implement?
- A. Apply cold packs to painful areas.
- B. Encourage increased fluid intake.
- C. Administer high doses of vitamin C.
- D. Provide low-calorie meals.
Correct answer: B
Rationale: Encouraging increased fluid intake is crucial in managing vaso-occlusive crises in patients with sickle cell anemia. Dehydration can worsen these crises, so adequate hydration is essential to prevent complications and improve outcomes. Applying cold packs to painful areas may exacerbate vaso-occlusive crises by causing vasoconstriction. Administering high doses of vitamin C is not directly indicated for vaso-occlusive crises in sickle cell anemia. Providing low-calorie meals is not the priority during a vaso-occlusive crisis; maintaining adequate nutrition is important, but hydration takes precedence in this situation.
3. 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.
4. The heart rate for a 3-year-old with a congenital heart defect has steadily decreased over the last few hours, now it's 76 bpm, the previous reading 4 hours ago was 110 bpm. Which additional finding should be reported immediately to a healthcare provider?
- A. Oxygen saturation 94%.
- B. RR of 25 breaths/minute.
- C. Urine output 20 mL/hr.
- D. BP 70/40.
Correct answer: D
Rationale: A significant drop in heart rate and blood pressure should be reported immediately as it may indicate worsening of the congenital heart defect. A decrease in blood pressure may suggest poor cardiac output and compromised perfusion, requiring urgent medical attention. The other findings (oxygen saturation of 94%, RR of 25 breaths/minute, and urine output of 20 mL/hr) are within normal ranges for a 3-year-old and do not indicate immediate deterioration of the heart defect.
5. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction 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 correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.
