CASE PRESENTATION
Olive, a 4-month-old girl, presents to the emergency department (ED) with lethargy. Since being diagnosed with respiratory syncytial virus (RSV) bronchiolitis by her pediatrician 2 days ago, her parents report that Olive has been more listless, and they brought her into the ED today when she became difficult to arouse.
Upon arrival to the ED, Olive is noted to be lethargic and tachypneic, and she is uninterested in drinking. The ED physician orders several laboratory tests, including serum electrolytes. Olive’s laboratory test results are notable for a serum sodium level of 126 mEq/L (126 mmol/L). The ED physician calls you to discuss Olive’s case and requests that you consider her for admission.
