مريض يسأل لماذا يجب أن يغسل جهاز البخار ويجففه بعد كل استخدام. ما الإجابة الصحيحة؟

A client asks why he must wash and dry his nebuliser after each use. What is the correct answer?

1. Because water stops the drug reaching the lungs
2. Because the drug damages the device if left in it
3. To prevent bacterial and fungal growth
4. Because the device must cool before the next use

Answer: C) To prevent bacterial and fungal growth. Residual moisture lets organisms grow in the nebuliser cup and mask, so parts are washed, dried and replaced as instructed to prevent respiratory infection.
