Question

Which of the following diseases may be diagnosed using a CXR?

1) CHF
2) PTX
3) PE
4) Rib fracture
5) PNA
6) Heart function
7) Asthma

Answer 1

A CXR can help diagnose CHF, PTX, PE, rib fractures, and pneumonia. It provides additional information about heart function but is not a direct diagnostic tool for asthma.

Step-by-step explanation:

A chest x-ray (CXR) can be used to diagnose several diseases related to the respiratory system. From the given options, the following can be diagnosed using a CXR:

1. CHF (Congestive Heart Failure): Although CXR primarily helps in evaluating the heart, it can show changes in the size and shape of the heart that are indicative of CHF.
2. PTX (Pneumothorax): CXR can detect the presence of air in the space between the lung and chest wall, which is characteristic of PTX.
3. PE (Pulmonary Embolism): CXR may not directly diagnose PE, but it can be used to rule out other conditions and provide additional information when evaluating for PE.
4. Rib fracture: CXR can identify fractures in the ribs.
5. PNA (Pneumonia): CXR is commonly used to diagnose pneumonia by showing infiltrates or consolidation in the lungs.
6. Heart function: CXR can provide information about the size and shape of the heart, which indirectly reflects its function but is not a direct diagnostic tool.
7. Asthma: CXR is not typically used to diagnose asthma, as it primarily involves evaluating the airway function through pulmonary function tests.
