b. Too much water in the circuit
c. Calibration error in the galvanic fuel cell
d. Clogged jet orifice in the nebulizer - ANS ✓b. Too much water in the circuit

respiratory rate of 26/min and is showing signs of increased labor of
breathing. The mandatory rate is 14/min. Which of the following would
most likely help the patient?
a. Use of pressure support
b. Switch to pressure control ventilation
c. Increase the machine flow rate
d. Increase PEEP - ANS ✓a. Use of pressure support
A patient is experiencing atrial arrhythmias and is complaining of light-
headedness and nausea. Which of the following should the respiratory
therapist recommend to help remedy the problem?

When analyzing the FIO2 for an infant in an oxygen hood receiving oxygen
therapy with a blender set at 50%, the respiratory therapist notes an
oxygen concentration of 35% near the patient's mouth. The jet nebulizer
entrainment setting is set to 50%. To correct the problem, the therapist
should
a. Obtain a smaller oxyhood
b. Increase total flow to the oxyhood
c. Adjust blender setting to 60%
d. Change the nebulizer entrainment port to 100% - ANS ✓d. Change the
nebulizer entrainment port to 100%
Following the insertion of a tracheostomy tube, the patient is found to have
diffuse crackles upon auscultation secondary to subcutaneous emphysema.

Placement of a pulmonary artery catheter is associated with which of the
following most common complications?
a. Internal bleeding
b. Pulmonary valve damage
c. Hypotension
d. Cardiac arrhythmias - ANS ✓d. Cardiac arrhythmias
During the placement of a pulmonary artery catheter, the respiratory
therapist observes the waveform on the monitor and notices it is
repeatedly rising and falling from 0 mmHg to 25 mmHg, which is an
indication that the tip of the catheter is in the right ventricle of the heart.
Based on this information, the respiratory therapist will recommend
a. Rotate the catheter to achieve a dicrotic notch in the waveform
b. Suture the catheter in place
c. Withdraw the catheter back to the upper vena cava
d. Inflate the catheter balloon to sail the tip to the proper location - ANS ✓d.
Inflate the catheter balloon to sail the tip to the proper location

not be indicated?
a. MVV
b. MIP
c. VC
d. VT - ANS ✓a. MVV
