An oral pharyngeal airway is measured from the patient's jaw angle to the tip of the chin. After
placement, the semi-conscious patient repeatedly pushes the airway out with his tongue. The
therapist should
A. insert a larger airway.
B. replace with a nasal endotracheal tube
C. reinsert the oral airway.
D. secure the airway with tape. C. reinsert the oral airway.
It is normal for a patient to reject an oral airway with their tongue. Reinserting the airway is most
appropriate.
A respiratory therapist changes from a normal adult ventilator circuit to a heated-wire circuit.
Arterial blood gases are as follows:
pH 7.31 PaCO2 48 torr
PaO2 81 torr
HCO3- 24 mEq/L
, Lindsey Jones J test Questions And Answers
BE 0 mEq/L
Which of the following changes is most indicated?
A. increase inspiratory flow rate
B. revert to the normal non-heated wire circuit
C. remove 50-100 mL of deadspace between the wye and patient
D. add 100 mL of deadspace at the patient-ventilator interface C. remove 50-100 mL of
deadspace between the wye and patient
Removing deadspace is the best option and is the only option that will reduce carbon dioxide.
What also makes this appropriate is the fact that CO2 is off target by a very small amount,
making a change in deadspace appropriate.
A patient in the emergency room, who is breathing rapidly and deeply, is receiving heated
aerosol by mask and large-volume nebulizer with FIO2 set at 1.0 and the flow set at 15 L/min.
The therapist notices the aerosol disappears completely with each breath. Pulse oximetry shows
an oxygen saturation of 88%. The therapist should recommend
A. switch to a non-rebreathing mask at the same flow
, Lindsey Jones J test Questions And Answers
B. increase flow to 20 L/min
C. decrease FIO2 to 0.6
D. a tandem aerosol device D. a tandem aerosol device
A large volume nebulizer set at 60% with a flow of 15 L/min is producing a total gas flow of 15
L/min. Because this patient is breathing rapidly and deeply and is hypoxic, it is likely that the
total flow is not meeting the inspiratory demands of the patient. Because the flow of the large-
volume nebulizer may not be increased significantly due to back pressure the solution for this
case is to add another tandem large-volume nebulizer device, producing a total gas flow of 30
L/min.
A respiratory therapist is assisting in a cardiopulmonary stress testing of a patient. After several
increases in workload by increasing the incline on the treadmill, heart rate is 120/min, blood
pressure is 130/95 mmHg and O2 Sat is 97%. Increasing the treadmill further shows no further
increase in these values, but the patient appears pale in color. The therapist should recommend
A. after two minutes, increase workload
B. discontinue the test, document findings
C. monitor the patient closely
D. decrease workload B. discontinue the test, document findings

The laboratory results of a sputum culture and sensitivity have returned for a patient who has
bilateral bacterial pneumonia. The culture reveals streptococcus, a gram-positive bacteria. The
medical records indicates the patient is allergic to penicillin. Which of the following should the
respiratory therapist recommend?
A. Amoxicillin
B. Cephalexine (Keflex)
C. Methacillin
D. Nafcillin B. Cephalexine (Keflex)
Normally gram-positive bacteria may be killed by penicillin-type antibiotics. But, because the
patient is allergic to penicillin, a suitable drug is cephalexine. Nafcillin and methacillin are
suitable antibiotics when a patient is penicillin-resistant but not when they are allergic.
A patient with cystic fibrosis develops rhonchi after 5 minutes of PEP therapy at 20 cm H2O.
The respiratory therapist should
A. switching to flutter therapy
B. discontinue treatment, report to findings to the physician
