b. They do not require good hand-breath co-ordination.

ANS: A
Breath-actuated nebulizers generate aerosol only during inspiration. It is true that breath-actuated pressure metered dose inhalers do not require good hand-breath coordination, and because of that they decrease aerosol medication waste. Patients with severe airway obstruction may not have the capability of generating enough flow to trigger the breath actuator.
