1250 Module 6

What adjustable control determines the amount of aerosol produced during the administration of bland aerosol therapy?

• Amplitude
• Frequency
• Flow rate
• Sensitivity

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

The most common devices used for bland aerosol therapy include all of the following EXCEPT:

• Large volume nebulizer (LVN)
• Small volume nebulizer (SVN)
• Air entrainment nebulizer (AEN)
• Bubble humidifier

Hypertonic saline is indicated for which of the following conditions?

• Sputum induction
• Asthma exacerbation
• COPD
• Laryngotracheobronchitis (croup)

During oxygen rounds you come across a patient with a heated humidification system. Where should you expect to find condensation (water buildup) in this system?

• at the connection between the tracheostomy collar...
• at the lowest point in the patient circuit
• at the connection between the air entrainment...
• at the highest point in the patient circuit

A patient in the hospital is utilizing a manual large volume nebulizer (LVN) to reduce upper airway swelling. What type of water should be used to fill the nebulizer?

• Sterile water
• Tap water
• Hypertonic saline
• Albuterol

A Respiratory Therapist is preparing to administer bland aerosol therapy to a patient. What is the most appropriate action to increase the aerosol output from the nebulizer?

• Increase the temperature of the sterile water

• Decrease the surface area of the sterile water

• Decrease the contact time with the sterile water

• Increase the flow rate of the gas as it passes over the sterile water

What is the total flow output when using a 35% air entrainment adapter with 8 L/min oxygen?

• 36 L/min
• 42 L/min
• 47 L/min
• 53 L/min

The oxygen/air ratio for the 35% air entrainment mask is:

• 6 : 1
• 10 : 1
• 4.3 : 1
• 25 : 1

Total flow for a 35% air entrainment mask at 10 L/min is ____ L/min.

• 43
• 53
• 33
• 23

Total flow for a 50% air-entrainment mask at 8 L/min is ____ L/min.

• 18
• 73
• 21

• 51
