What should be monitored after a pneumonectomy?

1. Blood pressure

2. Fluid intake

3. Breath sounds

4. Urine output

The correct answer is: Breath sounds

Monitoring breath sounds after a pneumonectomy is crucial due to the surgical removal of one lung, which significantly alters the patient’s respiratory mechanics. After this major surgical procedure, the patient's ability to breathe and oxygenate blood is compromised, and any changes in breath sounds can indicate complications such as atelectasis, fluid accumulation, or infection. It is essential to regularly assess for abnormal breath sounds like wheezing, crackles, or diminished breath sounds, which can provide immediate insight into respiratory status and the potential need for further interventions such as supplemental oxygen or chest physiotherapy. While blood pressure, fluid intake, and urine output are important parameters to monitor in the post-operative setting, breath sounds are uniquely critical in the context of lung function following pneumonectomy. The focus should be on ensuring adequate ventilation and oxygenation, thus making breath sounds a priority in post-surgical assessments.
