Answer to Question 1

cyanide gas
For safety reasons, rescue workers should be upwind and uphill from a toxic chemical disaster scene to avoid exposure. The exception is when cyanide gas has been released. Cyanide is lighter than air and thus will travel uphill. It has the unique smell of bitter almonds.

Answer to Question 2

C
After the inner cannula is thoroughly cleaned, it is rinsed with normal saline. The inner cannula is removed and is placed in a basin of normal saline to loosen secretions. It is scrubbed and then rinsed with normal saline. The outer cannula is not cleaned on the inside. The exposed outer cannula surfaces at the stoma are dried with a 4 4 gauze to prevent a moist environment and prohibit microorganism growth and skin excoriation.
