Nursing Elites

1. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperpneic. Which action should the nurse implement first?

• A. Administer morphine sulfate.
• B. Start IV fluids.
• C. Place the infant in a knee-chest position.
• D. Provide 100% oxygen by face mask.

Correct answer: C

Rationale: In a situation where an infant with tetralogy of Fallot is acutely cyanotic and hyperpneic, the priority action should be to place the infant in a knee-chest position. This position helps increase systemic vascular resistance, improving pulmonary blood flow and subsequently ameliorating the cyanosis and hyperpnea. It is a non-invasive and effective intervention that can be promptly implemented by the nurse to address the immediate respiratory distress. Administering morphine sulfate (Choice A) is not the priority in this case as it may cause further respiratory depression. Starting IV fluids (Choice B) may not address the immediate cyanosis and hyperpnea. Providing 100% oxygen by face mask (Choice D) can help with oxygenation but may not be as effective as placing the infant in a knee-chest position to improve blood flow dynamics.

2. 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.

3. Before administering a tube feeding to a child, what should the practical nurse (PN) assess?

• A. Tube placement.
• B. Bowel sounds.
• C. Abdominal circumference.
• D. Tube patency.

Correct answer: A

Rationale: Assessing tube placement is critical before initiating a tube feeding to verify its correct positioning in the stomach. This assessment helps prevent potential complications such as aspiration if the tube is incorrectly placed in the respiratory tract. Checking bowel sounds, abdominal circumference, and tube patency are important assessments in the care of a child receiving tube feedings, but ensuring proper tube placement takes precedence to ensure safe and effective delivery of nutrition.

4. A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant’s vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?

• A. Irregular palpable pulse
• B. Hyperactive bowel sounds
• C. Underweight for age
• D. Crying without tears

Correct answer: D

Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications. Irregular palpable pulse (Choice A) could indicate a cardiovascular issue but is less immediately life-threatening in this context. Hyperactive bowel sounds (Choice B) are more indicative of gastrointestinal issues rather than a life-threatening complication. Underweight for age (Choice C) may be concerning for growth-related issues but does not directly indicate a life-threatening complication like dehydration does.

5. The practical nurse is providing care for a toddler who has just returned from surgery for a tonsillectomy. Which intervention is a priority in the immediate postoperative period?

• A. Offer clear fluids frequently.
• B. Encourage the child to cough and deep breathe.
• C. Monitor for frequent swallowing.
• D. Apply a warm compress to the throat area.

Correct answer: C

Rationale: Monitoring for frequent swallowing is a priority intervention in the immediate postoperative period after a tonsillectomy. Frequent swallowing may indicate bleeding from the surgical site, which requires immediate attention to prevent complications such as hemorrhage. Offering clear fluids frequently may not be appropriate immediately after surgery. Encouraging coughing and deep breathing may increase the risk of bleeding. Applying a warm compress to the throat area is not recommended as it can increase blood flow to the surgical site, potentially causing bleeding.
