Answer to Question 1

ANS: A
Spacers and valved holding chambers are pressurized MDI accessory devices designed to reduce both oropharyngeal deposition and the need for hand-breath coordination.

Answer to Question 2

A spacer is a simple valveless extension device that adds distance between the pMDI outlet and the patient's mouth. See Box 39-2.
