Question 1

Accepted Answer

The answer of Which of the following devices would you...

Question 2

Which of the following nebulizers uses a piezoelectric transducer to generate liquid particle aerosols?

Accepted Answer

An ultrasonic nebulizer uses a piezoelectric transducer to generate liquid particle aerosols.

Question 3

What are some problems common to mist tents? I.heat retention II.CO₂ buildup III.hypothermia

Accepted Answer

Mist tents can lead to heat retention due to the humid environment they create, and CO2 buildup can occur if the tent is not properly ventilated. Hypothermia is unlikely as mist tents typically increase, not decrease, the temperature.

Question 4

The aerosol output (in mg/L) of an ultrasonic nebulizer depends mainly on which of the following?

Accepted Answer

The output of an ultrasonic nebulizer is mainly dependent on the signal amplitude and frequency. Higher signal amplitudes and frequencies result in higher aerosol output. Chamber baffling and source current have some impact but are not the main factors affecting aerosol output.

Question 5

To produce the highest possible density aerosol from an ultrasonic nebulizer, how would you set the controls? Amplitude
Flow

Accepted Answer

To produce the highest possible density aerosol from an ultrasonic nebulizer, the amplitude should be set high to generate more mist and the flow should be set low to allow the particles to be more concentrated, thus creating a denser aerosol.

Question 6

What is the total water output of unheated large-volume jet nebulizers?

Accepted Answer

Depending on the design, input flow, and air-entrainment setting, the total water output of unheated large-volume jet nebulizers varies between 26 and 35 mg H₂O/L.

Question 7

The particle size produced by an ultrasonic nebulizer depends mainly on which of the following?

Accepted Answer

The particle size produced by an ultrasonic nebulizer is mainly dependent on the signal frequency. The frequency determines the size of the cavitation bubbles produced, which in turn affects the particle size of the output.

Question 8

Which of the following would indicate that administration of a bland water aerosol to a patient with postextubation upper airway edema was having the desired effect?
I.decreased work of breathing
IIimproved vital signs
III.decreased stridor or dyspnea
IV.improved oxygen saturation

Accepted Answer

All of the options listed are potential signs of improvement when administering a bland water aerosol to a patient with postextubation upper airway edema. Decreased work of breathing (I) and improved oxygen saturation (IV) are direct indicators of improved respiratory function. Improved vital signs (II) may indicate a reduction in the strain on the cardiovascular system. Decreased stridor or dyspnea (III) would demonstrate a reduction in upper airway obstruction. Therefore, all four options (I, II, III, and IV) should be monitored to ensure the therapy is effective.

Question 9

For which of the following patients might you recommend administration of a hypertonic saline aerosol?
I.acquired immune deficiency syndrome (AIDS) patient with severe pneumonia symptoms
II.patient with a bypassed upper airway
III.patient suspected of having tuberculosis

Accepted Answer

Hypertonic saline aerosol can help to mobilize and thin mucus in patients with severe pneumonia symptoms (I) and tuberculosis (III), which can improve airway clearance. It may also be recommended for patients with a bypassed upper airway (II) to help loosen secretions and promote clearance. However, it is not recommended for all patients with respiratory conditions and should be used judiciously based on individual patient needs and symptoms.

Question 10

Which of the following are components of an ultrasonic nebulizer?
I.air-entrainment orifice
II.radiofrequency generator
III.nebulizer chamber
IV.piezoelectric transducer
V.blower or fan

Accepted Answer

An ultrasonic nebulizer typically includes a radiofrequency generator, a nebulizer chamber, a piezoelectric transducer, and a blower or fan. The air-entrainment orifice is not a component of an ultrasonic nebulizer.

Question 11

For which of the following patients might you recommend bland aerosol therapy via an ultrasonic nebulizer (USN)?
I.patient with upper airway edema
II.patient with a bypassed upper airway
III.patient who must provide a sputum specimen

Accepted Answer

The answer of For which of the following patients might...

Question 12

All of the following are true regarding large-volume jet nebulizers except:

Accepted Answer

Large-volume jet nebulizers generate liquid particles by using air pressure to pass the liquid through a small orifice, not mechanical vibration energy. This statement is true for ultrasonic nebulizers.

Question 13

What is the total water output of heated large-volume jet nebulizers?

Accepted Answer

According to the text, the total water output of heated large-volume jet nebulizers is between 33 to 55 mg H₂O/L. Option A and B are lower than this range, and option D is higher, so the best choice is C.

Question 14

What is the most common device used to generate bland aerosols?

Accepted Answer

Large-volume jet nebulizers are commonly used to generate bland aerosols for humidification and medication delivery in clinical settings.

Question 15

Which of the following mean mass aerodynamic diameter (MMAD) aerosol suspensions is produced by an ultrasonic nebulizer operated at 1.25 MHz?

Accepted Answer

The answer of Which of the following mean mass aerodynamic...

Question 16

Which of the following principles is used by the ultrasonic nebulizer to produce aerosol droplets?

Accepted Answer

Ultrasonic nebulizers use high-frequency vibrations to produce aerosol droplets. This is achieved by the device vibrating at very high frequencies, which generates pressure waves that break the liquid medication into tiny droplets. These droplets are then propelled out of the nebulizer as an aerosol mist. Evaporative cooling, mechanical baffling, and fractional distillation are not principles used by ultrasonic nebulizers to produce aerosol droplets.

Question 17

How often would you recommend that a home care patient disinfect a home ultrasonic room humidifier?

Accepted Answer

The answer of How often would you recommend that a...

Question 18

All mist tents prevent CO₂ buildup by what process?

Accepted Answer

High gas flows in mist tents help prevent CO2 buildup by ensuring a continuous supply of fresh air and the removal of exhaled CO2.

Question 19

A physician orders bland water aerosol administration to a patient with a tracheostomy. Which of the following airway devices could you use to meet this goal?
I.tracheostomy mask
II.face tent
III.T-tube
IV.aerosol mask

Accepted Answer

A tracheostomy mask is specifically designed to fit over a tracheostomy tube's outer cannula, which is not required for administering bland water aerosol. An aerosol mask or a face tent could be used, as they allow the aerosol to be delivered to the airway. A T-tube is not appropriate for delivering aerosol therapy. Therefore, the best choice(s) are I and III.

Question 20

A physician orders bland water aerosol administration to a patient with an intact upper airway. Which of the following airway appliances could you use to meet this goal?
I.simple oxygen mask
II.face tent
III.T-tube
IV.aerosol mask

Accepted Answer

A face tent or an aerosol mask can both be used to administer bland water aerosol to a patient with an intact upper airway. Simple oxygen mask and T-tube are not appropriate for this purpose.
