Nursing Elites

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

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

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

2. What is the most common cause of shock (hypoperfusion) in infants and children?

• A. infection
• B. cardiac failure
• C. accidental poisoning
• D. severe allergic reaction

Correct answer: A

Rationale: Infection is the most common cause of shock in infants and children due to their increased susceptibility to sepsis. Infants and children have underdeveloped immune systems, making them more prone to infections that can lead to septic shock. While cardiac failure is a serious condition, it is not the most common cause of shock in this population. Accidental poisoning, though dangerous, is less common than infection in causing shock in infants and children. Severe allergic reactions can lead to anaphylactic shock, but they are not as prevalent as infections in causing shock in this age group.

3. A 10-year-old girl is living with a foster family. Which intervention is the priority for the child in this family structure?

• A. Determining if the child is being bullied at school
• B. Dealing with mixed expectations of parents
• C. Establishing who is the child's actual caretaker
• D. Performing a comprehensive health assessment

Correct answer: D

Rationale: Performing a comprehensive health assessment is crucial for a child living with a foster family as they may have moved between different homes, leading to incomplete medical records. This assessment helps identify any existing health issues, ensure appropriate care, and address any unmet health needs. While addressing issues like bullying or parental expectations is important, the immediate priority should be ensuring the child's overall health and well-being. Establishing the actual caretaker is also important but may not be as urgent as addressing potential health concerns.

4. At 0345, you receive a call for a woman in labor. Upon arriving at the scene, you are greeted by a very anxious man who tells you that his wife is having her baby 'now.' This man escorts you into the living room where a 25-year-old woman is lying on the couch in obvious pain. Which of the following statements regarding crowning is true?

• A. Crowning represents the end of the second stage of labor.
• B. Crowning always occurs immediately after the amniotic sac has ruptured.
• C. It is safe to transport the patient during crowning if the hospital is close.
• D. Gentle pressure should be applied to the baby's head during crowning.

Correct answer: D

Rationale: During crowning, it is essential to apply gentle pressure to the baby's head to prevent rapid delivery, which can lead to potential injuries to both the mother and the baby. Choice A is incorrect because crowning signifies the beginning, not the end, of the second stage of labor. Choice B is incorrect as crowning can occur before or after the amniotic sac ruptures. Choice C is incorrect as transporting the patient during crowning, even if the hospital is close, can be unsafe due to the risk of rapid delivery and complications.

5. When caring for a child diagnosed with bronchiolitis, what is the priority nursing intervention?

• A. Administering bronchodilators
• B. Providing respiratory therapy
• C. Monitoring oxygen saturation
• D. Encouraging fluid intake

Correct answer: B

Rationale: The priority nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention aims to maintain airway patency, optimize oxygenation, and support effective breathing. Administering bronchodilators, though important, may not be the initial priority as respiratory therapy takes precedence in ensuring adequate oxygenation and ventilation. Monitoring oxygen saturation is crucial but is usually part of the ongoing assessment following the initiation of respiratory therapy. Encouraging fluid intake is essential for hydration but is not the priority intervention when addressing the respiratory distress associated with bronchiolitis.
