The most common, preventable complication of abdominal surgery is.. atelectasis

The most common, preventable complication of abdominal surgery is:

• atelectasis.
• fluid and electrolyte imbalance.
• thrombophlebitis.
• urinary retention.

The most common, preventable complication of abdominal surgery is atelectasis.

Atelectasis is the collapse of air sacs (alveoli) in the lungs, which can lead to decreased oxygen levels in the blood. This can occur after abdominal surgery due to several factors, including:

- Pain:

Pain can cause patients to avoid taking deep breaths, which can lead to atelectasis.

- Anesthesia:

Anesthesia can temporarily suppress the respiratory system, which can lead to atelectasis.

- Immobility:

Prolonged bed rest after surgery can lead to atelectasis.

Prevented:

Atelectasis can usually be prevented by encouraging patients to take deep breaths, providing pain relief, and encouraging early ambulation. If atelectasis does occur, it can usually be treated with supplemental oxygen therapy.

Complications:

The other complications listed are also common after abdominal surgery, but they are not as preventable as atelectasis. Fluid and electrolyte imbalance can occur due to dehydration or blood loss. Thrombophlebitis is a blood clot in a vein, and urinary retention is difficulty passing urine. These complications can be treated, but they can also lead to more serious complications if they are not treated promptly.

So, the answer is atelectasis.
