ATI Nursing Care of Children
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. The mother of a 6-month-old infant has returned to work and is expressing breast milk to be frozen. She asks for directions on how to safely thaw the breast milk in the microwave. What should the nurse recommend?
- A. Heat only 10 oz or more.
- B. Do not thaw or heat breast milk in a microwave oven.
- C. Always leave the bottle top uncovered to allow heat to escape.
- D. Shake the bottle vigorously for at least 30 seconds after heating.
Correct answer: B
Rationale: Thawing or heating breast milk in a microwave is not recommended because it can create hot spots that may burn the infant and destroy essential nutrients.
3. 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.
4. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)
- A. It is ready to be used immediately.
- B. All below
- C. There is less restriction of activity with a fistula.
- D. It produces dilation and thickening of the superficial vessels.
Correct answer: A
Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.
5. A child with acetylsalicylic acid (aspirin) poisoning is being admitted to the emergency department. What early clinical manifestation does the nurse expect to assess on this child?
- A. Hematemesis
- B. Hematochezia
- C. Hyperglycemia
- D. Hyperventilation
Correct answer: D
Rationale: Early signs of aspirin poisoning include hyperventilation due to the stimulation of the respiratory center and the resultant respiratory alkalosis. Hematemesis, hematochezia, and hyperglycemia can occur later in the poisoning process or may not be directly related to aspirin toxicity.
