Which of the following statements is consistent with a high-quality radiographic image?
1. Head of clavicles are level.
2. Spaces between vertebrae are distinct.
3. Lung parenchyma appear black and without blood vessels.
4. Cervical vertebral spaces are smaller than thoracic vertebral spaces. ✔✔1 and 2 only
An elevated brain natriuretic protein (BNP) level would be consistent with a diagnosis of....
✔✔Congestive Heart Failure
While monitoring the pressure waveform during insertion of a Swan-Ganz catheter, the RT notes
the presence of a dicrotic notch. This finding indicates that the tip of the catheter is inside the....
✔✔Pulmonary Artery
The RT has measured the exhaled nitric oxide concentration (FENO) of a patient with asthma.
The therapist notes a decrease in the patient's FENO levels from his last visit one month ago.
These results would be consistent with increased use of.... ✔✔Corticosteroids
,The RT discovers that a patient has dyspnea and diminished breath sounds with a flat percussion
note on the left. The chest radiograph indicates a tracheal shift to the right. What disease state
should the therapist suspect is affecting the patient? ✔✔Pleural Effusion
A patient is being monitored with a pulmonary artery catheter. The following measurements are
recorded:
CVP: 4 mmHg
Mean PAP: 18 mmHg
MAP: 84 mmHg
Cardiac Output: 4 L/min
What is the patient's systemic vascular resistance? ✔✔(MAP-CVP) / Cardiac Output
(84 - 4) / 4
80/4 = 20
Convert to dynes: multiply answer by 80
20 x 80 = 1,600 dynes/s/cm
,A 32-week gestation age infant is receiving mechanical ventilation with a time-cycled, pressure-
limited ventilator at the following settings:
SIMV
PIP: 28 cmH2O
RR: 22/min
FiO2: 60%
PEEP: 6
Flow: 6 l/min
I-time: 0.6 seconds
The RT notices the TcPO2 reading suddenly drops 39 torr. There have been no changes in the
vent settings, however the patient is cyanotic, the trachea is deviated to the right and the breath
sounds are absent on the left. A tympanic percussion note is detected over the left thorax. The
RT should recommend what? ✔✔Transillumination to detect a pneumothorax
Following insertion of a nasal endotracheal tube, the RT should inflate the cuff to: ✔✔22 mmHg
, Which suction catheter would be most appropriate to use for a patient with a size 7.5 mm ID
ETT? ✔✔(ID size / 2) x 3
7.5/2= 3.75 x 3 = 11.25
Round down to 10 Fr
While manually ventilating a 42-year-old woman following endotracheal intubation, the RT
notices that the manual resuscitation bag fills rapidly and collapses with minimal pressure. The
therapist also observes that the patient's chest has limited bilateral movement. The therapist
should... ✔✔Use another form of ventilation.
What is the most appropriate position for an obese patient with dyspnea? ✔✔Lateral Fowlers
While administering IPPB therapy to a 58-year-old man who recently underwent a colon
resection, the RT notes that the peak inspiratory pressure is not reaching the set value. This is
most likely the result of.... ✔✔insufficient inspiratory flow
After attaching a bubble humidifier to an O2 flowmeter, setting the flow at 5 L/min, and
occluding the humidifier outlet, the RT hears a whistling sound from the humidifier. This would
indicate.... ✔✔proper function of the humidifier
