What is the most common cause of bronchiolitis in infants?
- A. Adenovirus
- B. Influenza virus
- C. Respiratory syncytial virus
- D. Parainfluenza virus
Correct Answer: C
Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

What is the most effective way to prevent the spread of hand, foot, and mouth disease in a daycare setting?
- A. Handwashing
- B. Isolating sick children
- C. Disinfecting toys
- D. Encouraging vaccination
Correct Answer: A
Rationale: Handwashing is indeed the most effective way to prevent the spread of hand, foot, and mouth disease in children. Proper hand hygiene helps in removing and killing germs that can cause infections. While isolating sick children and disinfecting toys are important measures to prevent the spread of diseases, they are not as effective as handwashing. Encouraging vaccination, in this case, is not relevant since there is no specific vaccine available for hand, foot, and mouth disease.
The nurse is preparing to care for a newborn with an omphalocele. The nurse should understand that care of the infant should include what intervention?
- A. Initiating breast or bottle-feedings to stabilize the blood glucose level
- B. Maintaining pain management with an intravenous opioid
- C. Covering the intact bowel with a nonadherent dressing to prevent injury
- D. Performing immediate surgery
Correct Answer: C
Rationale: The priority intervention for an infant with an omphalocele is to cover the intact bowel with a nonadherent dressing to protect the exposed organs and prevent infection. This intervention is crucial to prevent injury and maintain the infant's safety. Initiating feedings or maintaining pain management are not the immediate priorities in the care of an infant with an omphalocele. Performing immediate surgery may be required in the future, but initially, covering the bowel is the first critical step in management.
Which of the following is the best indicator of a child's nutritional status?
- A. Weight
- B. Height
- C. Head circumference
- D. Mid-upper arm circumference
Correct Answer: D
Rationale: Mid-upper arm circumference is a good indicator of muscle mass and fat stores, reflecting a child's nutritional status. It is particularly useful in assessing malnutrition, as it is less affected by fluid retention or dehydration compared to other anthropometric measurements. Weight can fluctuate due to factors like hydration status, making it less reliable as a sole indicator of nutritional status. Height reflects growth but may not directly indicate current nutritional status. Head circumference is more related to brain growth and development rather than overall nutritional status.
What is the most important intervention in the management of a child with sickle cell crisis?
- A. Administration of iron supplements
- B. Initiation of high-calorie diet
- C. Administration of pain relief
- D. Limiting fluid intake
Correct Answer: C
Rationale: The most important intervention in managing a child with sickle cell crisis is the administration of pain relief. During a sickle cell crisis, severe pain is a prominent symptom due to vaso-occlusive episodes. Effective pain management, along with adequate hydration and oxygen therapy, is crucial in treating a sickle cell crisis and preventing further complications.
Choice A, the administration of iron supplements, is not the priority during a sickle cell crisis. Iron supplements are typically used to manage anemia in individuals with sickle cell disease but are not the primary intervention during a crisis.
Choice B, the initiation of a high-calorie diet, is not the most critical intervention during a sickle cell crisis. While proper nutrition is important in managing sickle cell disease, it is not the immediate priority during a crisis.
Choice D, limiting fluid intake, is not recommended during a sickle cell crisis. Hydration is essential in managing sickle cell crisis to prevent complications like dehydration and further vaso-occlusive episodes.
What disease should be suspected in a 3-day-old infant presenting with abdominal distention, vomiting, and failure to pass meconium?
- A. Pyloric stenosis
- B. Intussusception
- C. Hirschsprung disease
- D. Celiac disease
Correct Answer: C
Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.
