متى تكون مراقبة المريض أكثر أهمية أثناء نقل الدم؟

When is close observation most important during a blood transfusion?

1. Only the last 15 minutes
2. 24 hours after the transfusion
3. The first 15 minutes
4. Only halfway through the unit

Answer: C) The first 15 minutes. The most dangerous reactions usually occur in the first minutes, so transfusion starts slowly with the nurse present and vital signs checked.
