A nurse is assessing a 3-year-old child with autistic behaviors, an elongated facial structure, and protrusion of the ears. The nurse suspects that the child may have which of the following syndromes?
Trisomy 21
Fragile X
Turners Syndrome
Williams Syndrome
The Correct Answer is B
A. Trisomy 21, or Down syndrome, typically presents with features like intellectual disability, a flat facial profile, upward slanting eyes, and a small mouth. The elongated facial structure and ear protrusion are not characteristic of this condition.
B. Fragile X syndrome is associated with developmental delays, autistic behaviors, and distinct physical features such as a long face, large ears, and a prominent jaw. These characteristics are consistent with the child’s presentation.
C. Turner’s syndrome primarily affects females and is characterized by short stature, webbed neck, and gonadal dysgenesis, but it does not typically involve autistic behaviors or elongated facial features.
D. Williams syndrome involves a distinct set of features including a broad forehead, short nose, and full lips. It is not primarily associated with elongated facial features and ear protrusion.

Explanation
A. Encouraging vigorous physical activity is not appropriate for an infant with RSV, as it can worsen respiratory distress.
B. Antibiotics are not effective against RSV because it is a viral infection. Antibiotics should only be used for secondary bacterial infections.
C. Isolation is crucial to prevent the spread of RSV to other infants, especially in healthcare settings.
D. Bronchodilators may be used to help open the airways and ease breathing in some cases of RSV.
E. Small, frequent feedings are important to prevent dehydration, as infants with RSV may struggle with feeding due to difficulty breathing.
F. Oxygen therapy is often required to maintain adequate oxygen levels in infants with RSV, particularly if they are experiencing respiratory distress.
Correct Answer is B
Explanation
A. Improved hydration is important for managing symptoms but is not directly related to the effectiveness of a cool mist humidifier.
B. Stridor is a hallmark sign of airway obstruction and inflammation in laryngotracheobronchitis. A decrease in stridor indicates that the airways are less inflamed and the child is improving, which is a positive outcome of the humidification treatment.
C. A barking cough is characteristic of croup (laryngotracheobronchitis), and while treatment may help reduce symptoms, it may not resolve completely with the use of a humidifier.
D. While a decreased temperature may indicate improvement in a fever, it is not directly tied to the use of a humidifier. Stridor is a more specific sign of airway improvement in this condition.
