Nursing Elites

1. A nurse is caring for an infant born with exstrophy of the bladder. What does the nurse determine is the greatest risk for this infant?

• A. Infection
• B. Dehydration
• C. Urinary retention
• D. Intestinal obstruction

Correct answer: A

Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The bladder mucosa and adjacent tissues being exposed increase the susceptibility to infections. Dehydration (Choice B) is not the primary concern in this condition. Urinary retention (Choice C) is less likely as exstrophy of the bladder usually presents with constant dribbling of urine. Intestinal obstruction (Choice D) is not directly related to exstrophy of the bladder.

2. A nurse is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the nurse identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron levels
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

3. When caring for a child diagnosed with asthma, what is an important nursing intervention?

• A. Administering bronchodilators
• B. Encouraging physical activity
• C. Monitoring oxygen saturation
• D. Providing nutritional support

Correct answer: A

Rationale: Administering bronchodilators is a crucial nursing intervention for a child with asthma as it helps to open the airways and improve breathing. Bronchodilators work by relaxing the muscles around the airways, making breathing easier for the child. Encouraging physical activity may exacerbate asthma symptoms in some cases, so it is not recommended as a primary intervention. Monitoring oxygen saturation is important in assessing respiratory status, but administering bronchodilators would take precedence in this situation. Providing nutritional support is a general nursing intervention and not specific to managing asthma symptoms.

4. After a cardiac catheterization, what is the priority nursing care for a 3-year-old child?

• A. Encouraging early ambulation
• B. Monitoring the site for bleeding
• C. Restricting fluids until the blood pressure is stabilized
• D. Comparing the blood pressure of both lower extremities

Correct answer: B

Rationale: The priority nursing care after a cardiac catheterization in a 3-year-old is to monitor the site for bleeding. This is essential to promptly detect and manage any potential complications, such as hematoma or hemorrhage. Encouraging early ambulation, as mentioned in choice A, may not be safe immediately post-procedure and should be guided by the healthcare provider's instructions. Restricting fluids until blood pressure is stabilized, as in choice C, is not typically necessary after a cardiac catheterization. Comparing blood pressure in both lower extremities, as in choice D, is not the priority immediate nursing care following this procedure.

5. Upon assessing a newborn immediately after delivery, you note that the infant is breathing spontaneously and has a heart rate of 90 beats/min. What is the most appropriate initial management for this newborn?

• A. Begin positive pressure ventilations
• B. Provide blow-by oxygen with oxygen tubing
• C. Assess the newborn's skin condition and color
• D. Start chest compressions and contact medical control

Correct answer: A

Rationale: In a newborn, a heart rate below 100 beats/min indicates the need for positive pressure ventilation to improve oxygenation. Providing blow-by oxygen or assessing skin condition/color may not address the primary issue of inadequate oxygenation due to the low heart rate. Starting chest compressions and contacting medical control is not warranted as the newborn is breathing spontaneously and only has a slightly low heart rate, which can be managed initially with positive pressure ventilations.
