Nursing Elites

1. The mother of an infant diagnosed with bronchiolitis asks the nurse what causes the disease. How should the nurse respond?

• A. Respiratory syncytial virus (RSV)
• B. Haemophilus influenzae
• C. Parainfluenza
• D. Rotavirus

Correct answer: A

Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.

2. What is the leading cause of morbidity and mortality in children with cystic fibrosis?

• A. Respiratory infections
• B. Malnutrition
• C. Diabetes
• D. Liver disease

Correct answer: A

Rationale: Respiratory infections are the leading cause of morbidity and mortality in children with cystic fibrosis. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which predisposes these children to recurrent respiratory infections. Malnutrition and diabetes are common comorbidities in cystic fibrosis but are not the leading causes of morbidity and mortality in affected children. Liver disease can occur in cystic fibrosis but is less common than respiratory complications.

3. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?

• A. Gently tap over the site.
• B. Apply a cold compress to the site.
• C. Raise the extremity above the level of the body
• D. Use a rubber band as a tourniquet for 5 minutes.

Correct answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

4. What statement is an advantage of peritoneal dialysis compared with hemodialysis?

• A. Protein loss is less extensive.
• B. Dietary limitations are not necessary.
• C. It is easy to learn and safe to perform.
• D. It is needed less frequently than hemodialysis.

Correct answer: C

Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.

5. What is the most common cause of acute kidney injury in children?

• A. Dehydration
• B. Glomerulonephritis
• C. Hemolytic uremic syndrome
• D. Sepsis

Correct answer: C

Rationale: Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. While dehydration can lead to prerenal acute kidney injury, it is not the most common cause in children. Glomerulonephritis is a common cause of chronic kidney disease but not typically the most common cause of acute kidney injury in children. Sepsis can lead to acute kidney injury, but in children, hemolytic uremic syndrome is more prevalent.
