Question

A patient with euvolemia, hyponatremia, and a history of smoking is most likely experiencing which of the following conditions?

1) Pulmonary embolism
2) Chronic obstructive pulmonary disease (COPD)
3) Pneumonia
4) Lung cancer

Answer 1

The likely condition a patient with euvolemia, hyponatremia, and a history of smoking may suffer from is Chronic Obstructive Pulmonary Disease (COPD), often resulting from long-term smoking.

Step-by-step explanation:

A patient with euvolemia, hyponatremia, and a history of smoking is most likely experiencing Chronic Obstructive Pulmonary Disease (COPD). COPD is a respiratory condition that is often caused by long-term smoking and is characterized by chronic poor airflow. It leads to the breakdown of connective tissues in the lungs, reducing the number and elasticity of alveoli, which results in difficulty exhaling air fully from the lungs. This disease is incurable, but its progression can be slowed down by cessation of smoking, and symptoms may be managed with supplemental oxygen and inhaled bronchodilators.
