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. A 3-year-old child ingests a substance that may be a poison. The parent calls a neighbor who is a nurse and asks what to do. What should the nurse recommend the parent to do?

• A. Administer syrup of ipecac.
• B. Call the poison control center.
• C. Take the child to the emergency department.
• D. Give the child bread dipped in milk to absorb the poison.

Correct answer: B

Rationale: In cases of potential poisoning, immediate guidance from professionals is crucial. Administering syrup of ipecac is no longer recommended routinely due to potential risks and lack of benefit. Taking the child to the emergency department is necessary in severe cases but may not always be the immediate action needed. Giving the child bread dipped in milk is not an appropriate method to manage poisoning and could potentially worsen the situation. Therefore, the most appropriate action for the nurse to recommend is to call the poison control center for expert advice on managing the situation.

3. What should be the priority action when caring for a child with acute laryngotracheobronchitis?

• A. Initiate measures to reduce fever.
• B. Ensure delivery of humidified oxygen.
• C. Provide support to reduce apprehension.
• D. Continually assess the respiratory status.

Correct answer: D

Rationale: When caring for a child with acute laryngotracheobronchitis, the priority action should be to continually assess the respiratory status. This is crucial to detect early signs of respiratory distress, such as worsening stridor or increased work of breathing. Prompt intervention can prevent further deterioration of the child's condition. Initiating measures to reduce fever (Choice A) may be necessary but is not the priority in this situation. Ensuring delivery of humidified oxygen (Choice B) is important for maintaining oxygenation but should follow the assessment of respiratory status. Providing support to reduce apprehension (Choice C) is also important for the child's comfort but is not the priority over assessing and managing respiratory distress.

4. A healthcare professional is preparing a presentation for a parent group about musculoskeletal injuries. When describing a child's risk for this type of injury, the professional integrates knowledge that bone growth occurs primarily in which area?

• A. Growth plate.
• B. Epiphysis.
• C. Physis.
• D. Metaphysis.

Correct answer: B

Rationale: Bone growth primarily occurs in the epiphysis, which is the area where growth plates are located. The epiphysis is responsible for longitudinal bone growth. The growth plate, also known as the physis, is the cartilaginous region in the metaphysis where bone growth occurs. The metaphysis is the area between the epiphysis and diaphysis where bone lengthening occurs, but it is not the primary site of bone growth. Therefore, choices A, C, and D are incorrect.

5. A parent arrives in the emergency clinic with a 3-month-old baby who says, “My baby stopped breathing for a while.” The infant continues to have difficulty breathing, with prolonged periods of apnea. Which assessment data should alert the nurse to suspect shaken baby syndrome (SBS)?

• A. Birth occurred before 32 weeks’ gestation
• B. Lack of stridor and adventitious breath sounds
• C. Previous episodes of apnea lasting 10 to 15 seconds
• D. Retractions and use of accessory respiratory muscles

Correct answer: D

Rationale: Retractions and the use of accessory respiratory muscles can be signs of respiratory distress, which may indicate trauma such as shaken baby syndrome (SBS). Shaken baby syndrome can result in brain injury and respiratory compromise, leading to breathing difficulties. Choices A, B, and C are less likely to be associated with SBS. Birth before 32 weeks’ gestation is more related to prematurity rather than SBS. The lack of stridor and adventitious breath sounds, as well as previous episodes of apnea lasting 10 to 15 seconds, are not specific indicators of SBS.
