Answer to Question 1

D
Feedback:
Dry heat is a good technique for sterilizing sharp instruments and reusable syringes, because moist heat damages cutting edges and the ground surfaces of glass. Free-flowing steam is a method in which items are exposed to the heated vapor that escapes from boiling water. Steam under pressure is the most dependable method for destroying all forms of organisms and spores. Both gas and liquid chemicals are used to sterilize invasive equipment and may not be suitable for sterilizing instruments with a sharp edge.

Answer to Question 2

D
Feedback:
Boiling water is a convenient way to sterilize items used at home. To be effective, contaminated equipment needs to be boiled for 15 minutes at 212F or longer in places at higher altitudes.
