,1. A physician asks the respiratory therapist to measure a patient's ability to cough and
clear secretions from his airway. Which of the following is the most appropriate device
to evaluate the patient?
A. Wright respirometer
B. Peak flow meter
C. Aneroid manometer
D. Plethysmograph
C. Aneroid manometer
Aneroid manometer measures MIP/MEP
2. A patient is on a continuous flow CPAP system. The respiratory therapist notes that
the pressure drops to zero during inspiration. The therapist should
A. initiate mechanical ventilation.
B. change to an IPAP/EPAP system.
C. increase the flow to the patient.
D. decrease the threshold resistor.
C. increase the flow to the patient.
3. A patient with a history of chronic hypercapnia is admitted to the emergency
department complaining of shortness of breath and frequent coughing episodes. The
patient is expectorating inspissated, pale yellow secretions. The respiratory therapist
should recommend
A. sputum culture and sensitivity.
B. oxygen at 2 L/min via nasal cannula.
C. A-P and lateral chest x-rays.
D. arterial blood gas analysis.
B. oxygen at 2 L/min via nasal cannula.
4. A patient with known reversible airway disease takes two puffs of albuterol from his
metered-dose inhaler. The respiratory therapist measures the patient's peak flow
following the administration of the medication and determines that the peak flow has
increased only minimally. The therapist should
A. add a spacer to the metered-dose inhaler.
B. change the medication to levalbuterol.
C. administer the medication by small volume nebulizer.
D. contact the physician concerning the care of this patient
A. add a spacer to the metered-dose inhaler.

,5. A 32-week gestational age neonate receives CPAP by nasal prongs at 4 cm H2O.
During a routine bedside assessment, the respiratory therapist notes that the pressure
manometer is reading zero. The therapist should
A. confirm placement of the nasal prongs.
B. recalibrate the pressure manometer.
C. remove condensation from the circuit.
D. increase the flow to the neonate.
A. confirm placement of the nasal prongs.
6. A2-month-old infant is receiving 40% oxygen via an oxygen hood. While performing
oxygen rounds, the respiratory therapist analyzes the FiO2 inside the hood and
discovers that the FIO2 is registering 0.50. The respiratory therapist calibrated the
oxygen analyzer at the beginning of the shift. The respiratory therapist should
A. check to see that the hood is sealed tightly around the infant's neck.
B. decrease the flow to the hood.
C. check to see that the temperature setting on the humidifier is at 34°C.
D. recalibrate the oxygen analyzer.
D. recalibrate the oxygen analyzer.
7. A 44-year-old patient is cared for in a medical-surgical unit after undergoing lower
back surgery. The physician has written orders for postural drainage and percussion to
the right lower lobe for post-op complication of RLL pneumonia. During the therapy,
the patient suddenly vomits and aspirates. The respiratory therapist should
immediately
A. place the patient in Fowler's position.
B. encourage the patient to take deep breaths.
C. orally suction the patient with a yankauer device.
D. administer acetylcysteine by small volume nebulizer.
C. orally suction the patient with a yankauer device.
8. Air and oxygen flowmeters are used to deliver 40% oxygen to a patient via a non-
rebreathing mask. A total flow of 12 L/min is required to prevent the non-rebreathing
bag from deflating. How should the respiratory therapist set the flowmeters?
A. 2 L/min air, 10 L/min oxygen
B. 4 L/min air, 8 L/min oxygen
C. 6 L/min air, 6 L/min oxygen
D. 9 L/min air, 3 L/min oxygen
D. 9 L/min air, 3 L/min oxygen
9. A patient has been admitted to the emergency department after being rescued from a
house fire. The patient has second-degree burns on his neck and chest. The
respiratory therapist should administer oxygen therapy via
3
, A. non-rebreather mask.
B. simple oxygen mask.
C. air entrainment mask.
D. high-flow nasal cannula.
D. high-flow nasal cannula.
10. A patient with CO poisoning receives oxygen therapy by a non-rebreather mask at
10 L/min. The respiratory therapist notices that the reservoir bag on the mask is
emptying completely on inspiration. The therapist should
A. increase the flow to the device.
B. switch to a partial rebreather mask.
C. initiate mask CPAP therapy.
D. switch to a venturi-mask
A. increase the flow to the device.
11. The respiratory therapist administers an incentive spirometry treatment to a patient
recovering from a splenectomy. The therapist selected a flow-sensing incentive
spirometer to deliver the therapy. During the treatment, the therapist notes that the
float is not rising during inspiration. Which of the following could be the cause of this
situation?
1. A crack in the casing of the device
2. Patient's inspiratory effort is too strong
3. Improper seal around the mouthpiece
4. Patient is exhaling into the device
A. 1 and 4 only
B. 2 and 3 only
C. 1 and 3 only
D. 2 and 4 only
C. 1 and 3 only
12. A patient underwent a laryngectomy three days ago. The patient currently receives
50% oxygen with a cool aerosol via a tracheostomy collar. The respiratory therapist
notes that secretions being suctioned are thick and difficult to aspirate. The therapist
should recommend
A. increase the frequency of suctioning.
B. instill 2 mL of normal saline prior to suctioning.
C. decrease the FIO2 from the cool aerosol device to 45%.
D. add a heating element to the aerosol.
D. add a heating element to the aerosol.
