Which of the following statements about vibrating mesh nebulizers is false?

Question

a. They have no residual volume.
b. They reduce the contamination of medica-tion in the reservoir.
c. They are capable of generating aerosol from a single drop of liquid.
d. They can be used in closed systems during mechanical ventilation.

Answer 1

ANS: A
Vibrating mesh nebulizers do have residual drug volumes that range from 0.1 to 1.2 mL. As is not the case with jet nebulizers and ultrasonic nebulizers, the mesh acts as a physical barrier be-tween the drug in the medication reservoir and the body of the nebulizer in which the aerosol output is collected. This reduces the risk that exhaled pathogens will contaminate the medication in the reservoir. They can generate an aerosol from a single drop of liquid.
