امرأة عمرها ٥٠ سنة عندها أنبوب صدر لانصباب جنبي. أثناء مساعدتها في الحمام انفصل الأنبوب عن جهاز التصريف، والأنبوب نفسه ما زال في الصدر، وهي تتنفس بشكل طبيعي. ما التصرف الصحيح أولاً؟

A 50-year-old woman has a chest tube for a pleural effusion. While she is helped in the bathroom, the tube disconnects from the drainage system; the tube remains in her chest and she is breathing normally. What is the correct first action?

1. Leave the end open to air until a new unit arrives
2. Pull the tube out because it is contaminated
3. Clamp the tube for several hours until the doctor arrives
4. Put the end 2–3 cm under sterile water until reconnected

Answer: D) Put the end 2–3 cm under sterile water until reconnected. Submerging the end creates a temporary water seal that stops air entering, and a new unit is connected quickly. Prolonged clamping can cause tension pneumothorax.
