Which of the following statements is true concerning bland aerosols?
a. Bland aerosols should not be delivered to patients with tracheostomies.
b. Ultrasonic nebulizers are inefficient at producing bland aerosols.
c. Sterile water and hypotonic, isotonic, and hypertonic solutions can be used.
d. Humidifiers must be heated to deliver bland aerosols.
ANS: C
Sterile water and hypotonic, hypertonic, and isotonic solutions can all be used to create bland aerosols. If the patient has a tracheostomy, this requires the addition of a device that can produce high humidity. In most cases, this device would be the large-volume nebulizer, which produces bland aerosols. Ultrasonic nebulizers are very efficient at producing bland aerosols. Large-volume nebulizers (LVNs) do not need heat to produce bland aerosols.
