A 9-month-old child presents with fever, cough, dyspnea. The symptoms appeared 5 days ago after a contact with a person having URTI. Objectively: the child is in grave condition. Temperature of 38°C, cyanosis of nasolabial triangle is present. Respiration rate - 54/min, nasal flaring while breathing. There was percussion dullness on the right below the scapula angle, and tympanic sound over the rest of lungs. Auscultation revealed bilateral fine moist rales (crackles) predominating on the right. What is the most likely diagnosis?

Answer options

1. Acute bronchitis
2. Acute laryngotracheitis
3. Acute bronchiolitis
4. URTI
5. Acute pneumonia

Explanation

The percussion dullness and auscultation reveal bilateral fine moist rales predominating on the right lung, indicating acute pneumonia. Pneumonia is an inflammatory condition of the lung affecting primarily the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. Pneumonia is usually caused by infection with viruses or bacteria and less commonly by other microorganisms, certain medications, or conditions such as autoimmune diseases. People with infectious pneumonia often have a productive cough, fever accompanied by shaking chills, shortness of breath, sharp or stabbing chest pain during deep breaths, and an increased rate of breathing.
