A 65-year-old undomiciled man presents to your emergency department with complaints of fever, productive cough, and shortness of breath. He has a 40 pack-year history of smoking and daily alcohol consumption. His chest radiograph demonstrates a right upper lobe lung infiltrate with an air-fluid level. What is the most likely etiology for this finding?

Klebsiella pneumoniae:

Gram-negative encapsulated organism. Patients with klebsiella pneumonia commonly present with shaking chills, cyanosis, pleuritic chest pain, and a productive cough with characteristic currant-jelly sputum. Chest radiography reveals an infiltrate that is often in the upper lobes (most commonly the right) and is associated with a bulging fissure. If untreated, the infiltrate will progress into a necrotizing lesion with air-fluid levels, and can ultimately lead to development of an empyema.

Explanation:

The old man is sick with different symptoms. As a result, he must be diagnosed and examined to know the actual cause of the illness. This can be investigated by conducting a radiography test to check it there is any shrinkage in his organs such as lungs. Therefore, it is essential to conduct the test in order to reveal the findings.

the answer is c. absolute strength measures the greatest force exerted in a single effort, while relative strength measures strength adjusted for body size.
