D. administer racemic epinephrine by medication nebulizer
Give this one a try later!
D. administer racemic epinephrine by medication nebulizer
A 67yo female is receiving VC, AC ventilation. A RT is unable to advance a 14 Fr
suction catheter through the patient's 8.0mm cuffed tracheostomy tube. The RT
should:
A. exchange with an endotracheal tube
,B. instill normal saline
C. switch to a 6.0mm cuffed tracheostomy tube

A pt with exacerbation of COPD is receiving NPPV in spontaneous mode with a nasal
mask. The following data are available:
FiO2 : 0.24 RR : 28/min IPAP : 12 cmH2O EPAP: 6 cmH2O
One hour later, the following data are available:
pH : 7.27 PaCO2 : 76 mmHg PaO2 : 62 mmHg HCO3- : 35 mEq/L BE : +5 mEq/L
SaO2(calc) : 90%
The inspiratory phase is prolonged and dyssynchrony is noted. Which of the following
should a RT do FIRST?
A. Increase the FiO2 to 0.28
B. Increase to EPAP 8 cmH2O
C. Change to a full-face mask
D. Change the ventilator circuit
Give this one a try later!
C. Change to a full-face mask
A man presents to an ED following a 20-ft fall. During physical assessment, a RT
observes asymmetric movement of the left chest. This is most consistent with:
A. pneumomediastinum
B. lung contusion
C. hemothorax
D. flail chest
,Give this one a try later!
D. flail chest
A patient who was in a motor vehicle crash is receiving VC ventilation. The water-seal
chamber of the patient's chest drainage system bubbles toward the end of each
inspiration. Assessment shows the connecting tubing are intact and the chest tube is
properly placed. A RT should conclude that:
A. there is no suction pressure
B. suction pressure is excessive
C. the patient has a pleural leak
D. the drainage chambers are full
Give this one a try later!
C. the patient has a pleural leak
A 19yo pt with a spontaneous PNX is admitted to the hospital for observation. The pt is

0800: 82; 16; 112/79; 98
0900
1000
After initiating O2 by NRB mask, which of the following should the RT recommend?
A. noninvasive ventilation
B. needle decompression
C. CXR
D. ABG analysis
Give this one a try later!
, D. ABG analysis
For which of the following clinical conditions is bronchoscopy most useful?
A. pulmonary edema
B. pleural effusion
C. chronic bronchitis
D. lobar atelectasis
Give this one a try later!
D. lobar atelectasis
A 5'4" 19yo female with an acute asthma exacerbation is being treated in the ED with
continuous albuterol at 5mg/hr. After 1hr, the pt has clear bs and HR of 128/min and
peak flow of 350L/min. Which of the following should the RT do next?
A. change to scheduled albuterol at 2.5mg
B. administer IV corticosteroids
C. initiate heliox therapy
D. add ipratropium (atrovent) at 0.5mg
Give this one a try later!
A. change to scheduled albuterol at 2.5mg
Mechanical ventilation dead space is added while a patient is receiving mechanical
ventilation. The minute ventilation does not change. Which of the following will
increase?
