While performing oxygen rounds, the respiratory therapist visits a patient who is ordered
to receive 5 L/min by nasal cannula with a bubble humidifier. The therapist finds the
oxygen flow meter is reading 0 L/min, even though the knob is not in the off position,
and there is no flow to the patient. Which of the following may cause this?

A 9-year-old asthmatic patient has previously responded well to Xopenex via small-
volume nebulizer. The patient is intubated and has been placed on mechanical
ventilation for acute respiratory failure. The physician orders Xopenex to be delivered
via SVN through the ventilator circuit. Which of the following is an important
consideration for effective medication delivery?
A. particle deposition will be increased
B. an alpha I response is increased
, C. Placement of the nebulizer can result in variation of medication delivery
D. tachycardia is more likely - ANSWER-C
Which of the following resistors is not associated with pressurizing the circuit for a
patient receiving CPAP therapy?
A. water-column
B. weighted
C. spring-loaded
D. fixed orifice - ANSWER-D
While receiving nasal CPAP delivered by an infant ventilator, the patient is retracting
and creating a fluctuating baseline pressure on the monometer. What should the
respiratory therapist do?
A. Suction the patient
B. Adjust the threshold resistor
C. Increase the flowrate
D. Increase the size of the fixed orifice resistor - ANSWER-C
The respiratory therapist analyzes the oxygen percentage coming from the end of the
aerosol tubing on a large-volume, nebulizer. The analysis shows a higher oxygen
percentage than the set FIO2 on the air-entrainment device. Which of the following
could be the reason for this disparity?
A. depleted reservoir
B. clogged down tube in the nebulizer
C. kinked aerosol tubing
D. leak in the aerosol tubing - ANSWER-C
The respiratory therapist is performing a preoperational test of a ventilator. The therapist
notices the return volume is 200 mL less than the set tidal volume. The therapist should
A. tag the ventilator as non-functional and isolate it from functional equipment
B. notify the medical director and seek advice
C. accept the results and place the ventilator into service
D. check for a leak in the circuit or the circuit's connections - ANSWER-D
