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 child with a diagnosis of diabetes insipidus is admitted to the hospital. What is the priority nursing intervention?

• A. Administering insulin
• B. Monitoring fluid balance
• C. Administering diuretics
• D. Monitoring vital signs

Correct answer: B

Rationale: The correct answer is monitoring fluid balance. In a child with diabetes insipidus, the primary concern is excessive urination and fluid loss, which can lead to dehydration. Monitoring fluid balance is crucial to prevent dehydration and maintain electrolyte balance. Administering insulin (Choice A) is not indicated in diabetes insipidus, as this condition is not related to insulin deficiency. Administering diuretics (Choice C) should be avoided as it can exacerbate fluid loss in a child already at risk for dehydration. While monitoring vital signs (Choice D) is important, the priority intervention in this situation is monitoring fluid balance to prevent complications associated with dehydration.

3. What is an important nursing consideration for a child with a diagnosis of juvenile idiopathic arthritis (JIA) being treated with methotrexate?

• A. Monitor liver function tests regularly
• B. Encourage regular exercise
• C. Provide high-calorie snacks
• D. Encourage frequent handwashing

Correct answer: A

Rationale: The correct answer is to monitor liver function tests regularly. Methotrexate, commonly used in JIA, can be hepatotoxic. Regular monitoring of liver function tests is crucial to detect any signs of liver damage early. While encouraging regular exercise (choice B) is generally beneficial for overall health, it is not directly related to methotrexate therapy. Providing high-calorie snacks (choice C) is not a necessary consideration in this context and can be misleading. Encouraging frequent handwashing (choice D) is important for infection control but is not specifically related to the medication methotrexate.

4. Why does a cleft lip predispose an infant to infection?

• A. Waste products accumulate along the defect.
• B. There is evidence of inadequate circulation in the defective area.
• C. Nutrition is inadequate due to ineffective feeding.
• D. Mouth breathing dries the oropharyngeal mucous membranes.

Correct answer: D

Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.

5. A healthcare provider is assessing a child with suspected rheumatic fever. What clinical manifestation is the provider likely to observe?

• A. Jaundice
• B. Peeling skin on the hands and feet
• C. High fever
• D. Severe joint pain

Correct answer: D

Rationale: Severe joint pain is a classic symptom of rheumatic fever, resulting from inflammation of the joints. Rheumatic fever primarily affects the joints, heart, skin, and the central nervous system. Jaundice (Choice A) is not typically associated with rheumatic fever. Peeling skin on the hands and feet (Choice B) is more characteristic of conditions like Kawasaki disease. While high fever (Choice C) can be present in rheumatic fever, it is not as specific or characteristic as severe joint pain.
