مريض لديه فغر رغامى ويريد استخدام صمام الكلام. ما الشرط الأساسي قبل تركيبه؟

A client with a tracheostomy wants to use a speaking valve. What must be done first?

1. Close the inner cannula completely
2. Fully deflate the cuff
3. Give a sedative before fitting it
4. Inflate the cuff to the highest pressure

Answer: B) Fully deflate the cuff. A speaking valve lets air in through the tube but not out, so exhaled air passes through the vocal cords. If the cuff stays inflated, air cannot escape and the client can suffocate.
