When checking a servo-controlled heated-wire humidifier system being used with an invasive mechanical ventilator, the respiratory therapist notices that a few drops of condensate tend to form but only near the patient’s airway. The respiratory therapist should do which of the following?

Approximately how much water does the respiratory tract normally lose per day in heating and humidifying respired air?

While administering medicated aerosol therapy with a small volume nebulizer, the respiratory therapist observes the patient breathing rapidly and shallowly. What should the RT do at this time?

A doctor 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

What is the relative humidity of a gas that consists of 10 mg/L and a capacity of 25 mg/L.

A college student is brought to the emergency department following a motor vehicle accident. He is tachypneic and tachycardic and receives oxygen via a nonrebreather mask with a flow of 10 L/min. You observe that the reservoir bag is collapsing with each inspiration. The most appropriate action to take now is which of the following?

Calculate the humidity deficit for a person breathing air with an absolute humidity (content) of 23 mg H2O/L.

The relative humidity is 40%, and the capacity is 32 mg H2O/L.  What is the content (absolute humidity) of this gas?

The respiratory therapist administers a 35% aerosol mask to a patient. Several hours later, an oxygen analyzer is placed within the tubing and is reading 60%, but the large volume nebulizer setting remains at 35%. What action could be taken to fix this issue?

Choose the statements that describe the best breathing pattern for particle deposition in the lower airways when using a small volume nebulizer. I.   Inhale slowly.II.  Inhale rapidly.III. Inhale deeply through the nose.IV. Use a mouthpiece instead of a mask.V.  Hold the breath in for about 10 seconds before exhaling every few breaths.
