Question 1

When administering a medication via a small volume nebulizer to a patient,instruct the patient to take slow,deep breaths with a slight pause before exhaling.What is the purpose of the pause before exhaling?

Accepted Answer

This end-inspiratory pause will help the aerosol to deposit in the lungs.

Question 2

Back pressure exerted downstream from the nebulizer will cause ______________

Accepted Answer

Back pressure to the aerosol coming from the nebulizer will cause the FIO₂ to increase.

Question 3

Which of the following is NOT part of the preparation of a bubble humidifier for use on a patient?

Accepted Answer

Preparation consists of filling the reservoir with sterile,distilled water (unless unit is prefilled)but does not include testing for bacterial growth.

Question 4

Despite having the flowrate set on 15 LPM on a 30% aerosol to a T-piece,there is very little aerosol seen coming out of the aerosol tubing.What should the practitioner check?

Accepted Answer

The answer of Despite having the flowrate set on 15...

Question 5

Accepted Answer

A large-volume nebulizer is attached to a flowmeter with the DISS fitting at the top of the unit.

Question 6

A patient has an ultrasonic nebulizer ordered every 4 hours to help with secretion mobilization.After the treatment the patient complains of chest tightness and wheezing is heard upon auscultating the chest.What could be done to alleviate this problem?

Accepted Answer

The answer of A patient has an ultrasonic nebulizer ordered...

Question 7

A patient with a tracheostomy is receiving oxygen via T-piece.The physician orders 70% oxygen to be delivered by heated aerosol.The patient's inspiratory flowrate is 35 LPM.How should this oxygen therapy be set up on the patient?

Accepted Answer

The answer of A patient with a tracheostomy is receiving...

Question 8

When utilizing a Brigg's adaptor to connect the aerosol unit to a tracheostomy tube,a 6 inch piece of wide-bore tubing should be attached to the adaptor opposite the aerosol tubing coming from the nebulizer.What is the purpose of this tubing?

Accepted Answer

The Briggs adapter or aerosol 'T' is attached directly to the distal end of the aerosol delivery tubing.In addition,a short,6-inch piece of aerosol tubing is attached to the opposite end of the Briggs adapter.This serves as a 50-ml oxygen/aerosol reservoir,preventing room air entrainment when the patient first begins inspiration thus maintaining a constant FI0₂ delivered to the patient.
