مريضة تتعلم الغسيل البريتوني في البيت. أي خطوة تدل على تطبيق صحيح للتعقيم؟

A woman is learning home peritoneal dialysis. Which step shows correct aseptic technique?

1. Touch the connection ends to check they are clean
2. Connect the tubing in the bathroom as it is easier to clean
3. Heat the fluid bag in the microwave to warm it quickly
4. Wash hands, wear a mask and switch off fans before connecting

Answer: D) Wash hands, wear a mask and switch off fans before connecting. Hand hygiene, a mask and switching off fans and closing windows reduce contamination; connection ends are not touched, and bags are warmed with a dry heater, not a microwave.
