ASSESSMENT/PLAN: This is a 2-month-old, who presents with fever, paroxysmal cough and episodes of respiratory distress. The patient is currently stable in the emergency room. We will admit the patient to the pediatric floor. We will send out pertussis PCR. We will also follow results of urine culture and that the urine dip shows 10 to 25 bacteria. The patient will be followed up for signs of sepsis, apnea, urinary tract infection, and pneumonia. We will wait for a radiology reading on the chest x-ray to determine if the density seen on the lateral film is a normal variant or represents pathology.
