A 12-month-old girl is brought to the ED by her mother due to vomiting and lethargy for the past 24 hours. The patient is formula-fed and has had normal feeding patterns until several hours ago, when she had an episode of vomiting. The mother reports they were at a barbecue outside yesterday for several hours, but that the baby had proper coverage from the sun. The patient has a history of meconium ileus after birth, when she was subsequently tested and found to have a homozygous ΔF508 deletion in the CFTR gene. The patient’s temperature is 37.0°C (98.6°F), pulse is 134/min, respirations are 32/min, and blood pressure is 98/75 mmHg. Physical examination reveals a stuporous girl with dry mucous membranes.
