The nurse is planning to teach parents about prevention of Reye's syndrome. What information would the nurse include in this teaching?

C. Salicylates, such as aspirin, should be avoided in children and adolescents with viral symptoms due to the association with Reye's syndrome. Instead, acetaminophen or other non-steroidal anti-inflammatory drugs (NSAIDs) without salicylates should be used for fever and pain relief.

A. Reye's syndrome typically presents with symptoms such as fever, vomiting, and lethargy. However, there isn't a specific test for Reye's syndrome itself. Diagnosis is often based on clinical symptoms, history of aspirin use, and laboratory findings.

B. Reye's syndrome is associated with the use of aspirin (salicylates) in children and adolescents with viral infections, particularly influenza and chickenpox. Acetaminophen (Tylenol) is recommended instead of aspirin for fever and pain relief in children with viral illnesses.

D. There isn't a specific vaccine for Reye's syndrome. Reye's syndrome is not caused by an infectious agent that can be prevented through vaccination.

A. Wheezing. Cystic fibrosis can cause airway obstruction due to thickened mucus, leading to wheezing and difficulty breathing, especially during respiratory infections or exacerbations.

B. A barrel-shaped chest is often seen in advanced stages of cystic fibrosis. It results from hyperinflation of the lungs due to air trapping, chronic lung disease, and repeated respiratory infections. The chest appears rounded and enlarged, similar to the shape of a barrel.

D. Clubbing of fingers and toes is a common finding in cystic fibrosis. It is caused by chronic hypoxia and inadequate oxygenation of tissues, leading to changes in the nail beds and fingertips. Clubbing typically develops over time in individuals with chronic respiratory conditions, including cystic fibrosis.

C. Thin, watery mucous is not expected in cystic fibrosis. Instead, cystic fibrosis is characterized by thick, sticky mucus due to dysfunction of the exocrine glands, leading to blockages in the airways, pancreas, and other organs.

E. Rapid growth spurts are not typically associated with cystic fibrosis. In fact, children with cystic fibrosis may experience growth failure or delayed growth due to malabsorption of nutrients, chronic illness, and increased energy expenditure.
