Which of the following are beneficial effects of using a holding chamber with a metered-dose inhaler (MDI)? I.reduction in oropharyngeal aerosol deposition II.decrease in need for hand-breath coordination III.elimination of medication waste

To decrease the VDS of a small-volume jet nebulizer during drug administration, what should you do?

All of the following source gas characteristics affect the performance of small-volume jet nebulizers except:

Possible complications associated with the selection of an aerosol drug delivery device include all of the following except:

Which of the following small-volume jet nebulizer design features affect its performance? I.position II.residual volume III.baffles IV.reservoirs

What is the average mean mass aerodynamic diameter (MMAD) generated by the vibrating mesh nebulizers?

An asthmatic patient in severe distress with wheezing and dyspnea is admitted to the emergency department. After a conducting a full assessment and obtaining a pretreatment baseline, you start the patient on albuterol with a small-volume jet nebulizer. You should continue assessing and documenting all appropriate variables before and after each treatment until what point?

What measure is used to identify the particle diameter, which corresponds to the most typical settling behavior of an aerosol?

To ensure delivery of the proper drug dosage with a metered-dose inhaler, which of the following must be done before its use? I. The canister valve stem should be cleaned with a pin. II. The canister should be warmed to hand or body temperature. III. The canister should be vigorously shaken.

Indications of an adverse drug response during continuous bronchodilator therapy include all of the following except:

What is a potential limitation of flow-triggered metered-dose inhaler devices?

Which of the following is false about the optimal technique for using a small-volume jet nebulizer (SVN) for aerosol drug delivery?

After actuating a metered-dose inhaler with a holding chamber, what should the patient be instructed to do?

A physician has ordered the antiviral agent ribavirin (Virazole) to be administered by aerosol to an infant with bronchiolitis. Which of the following devices would you recommend in this situation?

Which of the following would you recommend to optimize drug delivery with a small-volume jet nebulizer (SVN) to an intubated, mechanically ventilated patient? I.Increase dose to compensate for decreased delivery.II.Place SVN in the inspiratory line 18 inches from the patient "wye." III.Disconnect or bypass heated humidifier system.IV.Turn off flow-by or continuous flow while nebulizing.V.Adjust ventilator volume or pressure limit for added flow.

The key difference between a metered-dose inhaler (MDI) holding chamber and a spacer is that the holding chamber incorporates which of the following?

Which of the following best defines an aerosol?

When assessing a patient's response to bronchodilator therapy, you notice a decrease in wheezing accompanied by an overall decrease in the intensity of breath sounds. Which of the following is most likely?

Normally, when using a 50-psi flowmeter to drive a small-volume jet nebulizer, to what should you set the flow?

When using a chamber-style adapter with a metered-dose inhaler (MDI) to deliver a bronchodilator to a patient receiving mechanical ventilation, with what would you coordinate MDI firing?
