MRCP2-0896
A 64-year-old man presents to the hospital with a history of several months of weight loss, shortness of breath and a productive cough which was sometimes accompanied by haemoptysis. A chest x-ray had revealed apical consolidation and sputum was positive for acid-fast bacilli, leading to a diagnosis of tuberculosis. The patient has a past medical history of asthma and takes PRN salbutamol and Seretide inhaler twice daily.
One week after being diagnosed, the patient is admitted to the acute medical unit with shortness of breath and bilateral expiratory wheeze. His observations reveal a temperature of 37.1ºC, respiratory rate of 27 breaths per minute and oxygen saturations of 94% on room air. Oxygen is commenced via a face mask. A chest x-ray reveals the same apical consolidation as before, with no new features.
What is the most appropriate next step in his treatment?
