Which causes of post-operative fever are common between days 5-10 post-surgery?

1. Urinary tract infection and drug fever

2. Wound infection and infected hematoma

3. Atelectasis and pneumonia

4. Both A and B

The correct answer is: Both A and B

The causes of post-operative fever that are commonly observed between days 5 to 10 following surgery include urinary tract infections and drug fever, as well as wound infections and infected hematomas. During this time frame, patients are at risk for various complications. Urinary tract infections can occur due to catheter use or immobility, which often leads to urinary retention and subsequent infection. Drug fever can arise as a reaction to medications administered during or after the surgical procedure, manifesting as fever without other clinical signs of infection. Additionally, wound infections and infected hematomas are critical considerations during this period of recovery. A wound infection may develop due to bacterial contamination either during the surgery or from post-operative care, leading to localized inflammation and fever. An infected hematoma, where blood collects and subsequently becomes infected, can also present with fever and may require drainage or further intervention. Given that both sets of causes are relevant in this timeframe, option D accurately reflects the multiple potential sources of fever during days 5-10 post-surgery. Understanding these potential complications is vital for effective post-operative care and timely intervention.
