Which of the following is a common complication of polycystic kidney disease?

A. A pneumothorax, or collapsed lung, occurs when air enters the pleural space, leading to lung collapse. While a pneumothorax can be a serious issue, it is not a typical finding associated with advanced COPD.
B. Hyperinflation is a hallmark finding of advanced COPD. It occurs when air becomes trapped in the lungs due to obstructed airways and damaged alveoli, leading to increased lung volumes and overexpansion of the lungs. On a chest X-ray, hyperinflation appears as an increased retrosternal air space, flattened diaphragm, and possibly increased lung volumes.
C. The presence of masses on a chest X-ray might suggest malignancies or other lung pathologies, but it is not a typical finding in COPD. While lung cancer can co-occur with COPD, masses themselves are not a direct indicator of COPD but rather a potential separate issue that would need further evaluation.
D. Atelectasis refers to the collapse of lung tissue due to loss of air in the alveoli, which can occur from various causes including obstruction or compression of the lung. While atelectasis can be seen in various pulmonary conditions, it is not specific to advanced COPD.

A. Hypernatremia (elevated sodium levels) is not a common sign of Addisonian crisis. In Addisonian crisis, the lack of aldosterone leads to sodium loss, which often results in hyponatremia (low sodium levels) rather than hypernatremia. The patient might also experience dehydration and electrolyte imbalances, but hypernatremia is not typical in this scenario.
B. Fluid volume overload is not characteristic of Addisonian crisis. Instead, Addisonian crisis often leads to fluid volume deficit due to the loss of aldosterone, which impairs sodium and water retention. This can result in dehydration and low blood volume rather than fluid overload.
C. Hypokalemia (low potassium levels) is not typically associated with Addisonian crisis. In fact, the lack of aldosterone in Addisonian crisis leads to potassium retention, resulting in hyperkalemia (elevated potassium levels). Therefore, monitoring for hypokalemia is not relevant in the context of Addisonian crisis following a bilateral adrenalectomy.
D. Hypoglycemia (low blood glucose levels) is a key sign of Addisonian crisis. Cortisol plays a crucial role in glucose metabolism and maintaining blood glucose levels. With the loss of cortisol production after a bilateral adrenalectomy, patients may experience hypoglycemia, which can be a critical indicator of Addisonian crisis.
