3. A clogged filter or capillary tube on a jet nebulizer has what effect on the operation of
the device? - Correct Answer: Decreased water output
4. List 5 clinical indications for aerosol therapy - Correct Answer: Improved secretion
mobilization, increased delivery of aerosolized medication, prevent dehydration, induce
cough, relieve upper airway inflammation, and hydrate airways
5. How should a patient be instructed to breathe - Correct Answer: slow, deep breaths
with 2-3 second hold on inspiration
6. What is the objective of humidity therapy? - Correct Answer: make up for water loss
that occurs due to dry gas administration or when upper airway is bypassed
7. Water capacity at body temperature - Correct Answer: 44 mg/L
,8. Name 3 factors that affect humidity operation - Correct Answer: duration of contact
between gas and water, surface area, and temperature
9. What dose reaches the lower respiratory tract when given by MDI? - Correct
Answer: 10%
10. Humidity deficit - Correct Answer: inspired air that is not fully saturated at body
temperature
11. Perfusion in the extremities may best be determined by which method? - Correct
Answer: Assessing capillary refill
12. While palpating the chest, the RT determines there are decreased vibrations over RLL.
This may be the result of; - Correct Answer: Pneumothorax and effusion
13. A CXR obtained after intubation shows the tip of the ETT resting at the fourth rib. What
action should be taken? - Correct Answer: Tube should be withdrawn 3 cm
14. A patient is suspected of having intrathoracic metastatic disease. Which imaging study
should the RT recommend to determine whether the disease is present? - Correct
Answer: PET
15. Which imaging study/studies may be useful in determining whether a pulmonary
embolism is present? - Correct Answer: MRI and CT
16. Which muscles are used for normal ventilation? - Correct Answer: External
intercostals and diaphragm
,17. Name two conditions in which hyperresonance percussion is noted - Correct
Answer: pneumothorax, emphysema
18. Name two conditions in which dull percussion is noted - Correct Answer: effusion,
consolidation
19. What does a decrease in Hb, HCT, and RBC indicate? - Correct Answer: Inadequate
oxygen carrying capacity
20. Patients with decreased platelet count and increased PT are at greater risk for what
occurrences? - Correct Answer: Hemorrhaging
21. A patient has just been intubated and the CO2 detector placed on the proximal end of
the ETT reads 1.5%. What should the RT suspect? - Correct Answer: The tube is in
the esophagus
22. McGill forceps are used during what procedure? - Correct Answer: Nasotracheal
intubation
23. The physician wants to begin weaning a patient from a tracheostomy tube. How may this
be best accomplished? - Correct Answer: Change to a fenestrated trach
24. You are called to a patient's room because a ventilator alarm is sounding. You hear an
audible leak around the patient's ETT during a ventilator breath and notice the exhaled
volume is reading 150 mL less than the set VT. You check the cuff pressure and find it's
12 mmHg. What is the most appropriate action to take? - Correct Answer: While
listening with a stethoscope at the larynx, instill air into the cuff until a slight leak is
heard on inspiration
, 25. You want to pass a suction catheter into the patient's left lung to obtain a sputum
specimen. What is the most appropriate method to accomplishing this? - Correct
Answer: Use a coude suction catheter
26. To prevent venous congestion on the tracheal wall, the ETT cuff should be maintained
below what level of pressure? - Correct Answer: 20 cmH20
27. Inspiratory stridor is a major clinical sign of what airway condition? - Correct Answer:
Glottic edema
28. List some problems associated with use of oral ETT - Correct Answer:
29. What is the maximum amount of suction pressure that may be used to suction an adult
patient's airway? - Correct Answer: -120 cmH20
30. When extubating a patient, the ETT should be withdrawn at what point in the breathing
cycle? - Correct Answer: Peak inspiration
31. What level must oxygenated Hb decrease by prior to cyanosis occurring? - Correct
Answer: 5 g/dL
32. abnormal sound heard over the heart, arteries, or veins caused by turbulent blood flow
or obstruction - Correct Answer: bruit
33. Most common position for chest x-ray - Correct Answer: Posterior Anterior
