A nurse is caring for an 18-month-old toddler in the emergency department. Exhibits For each potential assessment finding, click to specify if the finding is consistent with Epiglottitis, Respiratory Syncytial Virus, or Acute Streptococcal Pharyngitis, Each finding may support more than 1 disease process.

Rationale: Drooling: Drooling is classic in epiglottitis due to severe throat pain and an inability to swallow. It is not commonly seen in RSV or streptococcal pharyngitis, where swallowing remains relatively intact. Hypoxia: Both epiglottitis and RSV can cause hypoxia. In epiglottitis, airway obstruction can quickly compromise oxygenation. In RSV, hypoxia results from inflammation and mucus plugging in the small airways. Fever: Fever is a nonspecific but common finding across all three conditions. It signals an inflammatory or infectious process, whether viral (RSV), bacterial (Streptococcus), or in epiglottitis (often Haemophilus influenzae type b if unimmunized). Tachypnea: Tachypnea may occur in both epiglottitis and RSV as the body compensates for airway compromise and impaired gas exchange. It is not a typical feature of uncomplicated streptococcal pharyngitis. Exudate on pharynx: Pharyngeal exudates are common in streptococcal pharyngitis and help differentiate it from viral causes. They are typically absent in RSV and epiglottitis, where the pathology lies elsewhere (lower airways or supraglottic structures). Wheezing upon auscultation: Wheezing is a hallmark of RSV due to bronchiolar inflammation and narrowing. It is not seen in epiglottitis or streptococcal pharyngitis, as those conditions do not primarily affect the bronchioles.
