Step-by-step explanation:
A tall white male presenting with acute shortness of breath could be experiencing a variety of conditions. Given the symptoms described, including chest pain, coughing, nausea, and diarrhea, along with a fever of 40 °C (104 °F), it is possible that the individual may have a respiratory infection such as pneumonia or acute bronchitis. Additional tests that should be performed on the patient include sputum cultures to determine the type of infection and rapid influenza diagnostic tests (RIDTs) to rule out a possible viral infection. Proper diagnosis and treatment should be determined by a healthcare professional.
