A patient with a tracheostomy is receiving supplemental oxygen via tracheostomy collar connected to a large volume nebulizer set at 40%. The respiratory therapist analyzes the FIO2 at the tracheostomy collar with a galvanic fuel cell analyzer. The analysis shows the FIO2 to be 55%. Which of the following could be the cause of the increase in FIO2?(Ans - too much water in the circuit
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?(Ans - cardioversion

- / 3
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 (Ans - 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. Which of the following radiographic findings would be expected with this condition?(Ans - Hyperlucency in the soft tissues
Placement of a pulmonary artery catheter is associated with which of the following most common complications?(Ans - 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.
