When testing sputum, which of the following conditions may be assessed?

The choice indicating that all of the listed conditions may be assessed when testing sputum is correct because sputum analysis can provide valuable information regarding a variety of respiratory conditions. Sputum is a mixture of saliva and mucus that is coughed up from the respiratory tract, and analyzing it can reveal important diagnostic clues.

Cytology for tumor cells is significant because sputum samples can be examined for the presence of abnormal cells, which may indicate lung cancer or other types of malignancies. This is particularly useful in patients who have symptoms suggestive of lung cancer or have risk factors for the disease.

Pneumonia can be assessed through sputum testing by identifying the presence of pathogens such as bacteria or fungi. A culture or microscopic examination of the sputum can help determine the causative agent of the infection, guiding appropriate treatment.

Tuberculosis is another critical condition assessed through sputum analysis. Sputum samples can be screened for Mycobacterium tuberculosis, the bacteria responsible for TB. This is essential for confirming a diagnosis, especially in patients presenting with chronic cough, weight loss, or night sweats.

Therefore, sputum testing is a versatile diagnostic tool that can effectively assess various conditions, including the presence of tumor cells, pneumonia, and tuberculosis
