A 5-year-old boy is brought to the emergency department by his parents for evaluation of a persistent cough. The patient’s mother recalls, “He’s been coughing non-stop for weeks, but we got really worried tonight after he turned blue during an episode and threw up after another.” The patient was born full-term at home with assistance from a midwife. He has been evaluated by a physician only once shortly after he was born. Temperature is 38.7°C (102°F), pulse is 140/min, respirations are 30/min, blood pressure is 110/53 mmHg, and oxygen saturation is 95% while on room air. On physical examination, the patient has a long series of coughs, during which he has very few respirations. Shortly afterwards, the patient has one episode of non-bloody emesis. Which of the following investigations will most likely help confirm the patient’s diagnosis? Elimination tool Choose an option: Chest radiography Nasopharyngeal swab for influenza A and B Oropharyngeal streptococcal antigen testing Sputum culture on chocolate agar PCR-assisted identification of Bordetella DNA
