Children can present with new onset diabetes in diabetic ketoacidosis. Manifestations include
signs of dehydration ( dry mucous membranes, hypotension, tachycardia), incontinence
(polyuria), vomiting, abdominal pain, Kussmaul respirations (to counter the acidosis), polydipsia,
anorexia, and weight loss. Expected laboratory values would reveal an acidotic state with a pH

mg.dL.
An 18-month-old is seen for fever, slight circumoral cyanosis, and wheezing noted on
auscultation in the right upper lobe of the lung field after a choking event 4 days ago. The white
blood cell count is elevated and the patient noted to be tachypneic, tachycardic, agitated, and
has an increased respiratory effort. At the time of the event, the patient was started on
antibiotics with subsequent increasing manifestations instead of improvement. Which of the
following would be considered to be definitive treatment for the suspected diagnosis? - ANS
Computed tomography (wrong)
Remediation feedback:
Manifestations of a lower airway foreign body include a choking incident with subsequent failure
to improve on antibiotics. Wheezing or decreased lung sounds in one area of the pulmonary
system is a high indicator for a foreign body along with signs of hypoxia such as cyanosis,
tachypnea, tachycardia, increased respiratory effort, agitation or lethargy, and elevated white
blood cell counts indicating an infectious process. The definitive treatment would be a
bronchoscopy in order to retrieve the suspected foreign body instead of diagnostic tests to
locate the foreign body itself.
