ographic 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
2. An elevated brain natriuretic protein (BNP) level would be consistent with a
diagnosis of....: Congestive Heart Failure
3. 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
4. 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
5. 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
6. 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
7. 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
8. Following insertion of a nasal endotracheal tube, the RT should inflate the
cuff to:: 22 mmHg
9. 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
10. 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.
11. What is the most appropriate position for an obese patient with dyspnea?-
: Lateral Fowlers
12. While administering IPPB therapy to a 58-year-old man who recently under-
went 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
13. 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
14. A patient suffering from carbon monoxide poisoning is receiving 100% O2
via non-rebreather mask at a set O2 flow of 15 L/min. Each time the patient
inhales, the reservoir bag on the mask remains fully inflated. The therapist
should: seal the mask against the patient's face
15. What value for oxygenation index would indicate the need for ECMO in a
newborn?: 44
16. A 44-year-old male has been admitted to the hospital after being involved in
a sky diving accident. He is 193 cm (6ft 4 in) tall and weighs 82 kg (182 lbs). The

patient has been orally intubated with a size 8.5 ETT. A CXR reveals bilateral
opacification of all lung fields. Mechanical ventilation has been established
with a volume ventilator at the following settings:
Mode: VC, SIMV
Vt: 650 mL
RR: 12/min
FiO2: 0.65
PEEP: 10
PIP: 58
Plat: 50
ABG: pH 7.30, PaCO2 43, PaO2 45, HCO3 21, SaO2 82%
The patient's condition is most likely related to:: Venous admixture
17. Estimate the shunt fraction for a patient with the following available data:
A-aDO2: 200 torr
C(a-v)O2: 3.6 vol%
P/F Ratio: 400 torr: For each 100 mmHg in A-a, a 5% shunt occurs. Add 5% more
to that answer (due to normal shunting).
200 torr = 10% + 5% = 15% shunt
18. An 80kg (176 lb) patient in the post-anesthesia care unit following lower
abdominal surgery is receiving mechanical ventilation. Ventilator settings are
as follows:
VC, SIMV
Vt: 550 mL
f: 15/min
FiO2: 70%
PEEP: 15
ABG: pH 7.35, PaCO2 44 torr, PaO2 85 torr, HCO3 23, SaO2 99%, C(a-v)O2 10
vol%
The RT should:: Reduce the PEEP setting.
19. In preparation for assisting a pulmonologist with a fiberoptic bron-
choscopy for a 50-year-old woman receiving mechanical ventilation, the RT
notices that the patient appears to be anxious about undergoing the proce-
dure. The therapist should recommend administration of:: Midaxolam
20. The parameter that starts the inspiratory phase of a positive pressure
breath is referred to as the: trigger variable
21. While evaluating a patient receiving mechanical ventilation, the RT ob-
serves a persistent high pressure alarm. What could cause that situation?: -
Excessive secretions
