While performing a routine check of a patient receiving mechanical ventilatory
support, the respiratory therapist makes a small adjustment to the ET tube cuff
pressure by injecting 2.0 cc of air into the cuff. Immediately after, the high-
pressure alarm on the ventilator is activated. The therapist should
A. silence the alarm and monitor the patient closely.
B. remove the ET tube.
C. readjust the cuff using the minimal leak technique.
D. attempt to pass a suction catheter through the ET tube. - ANSWER-D.
The activation of the high-pressure alarm is an indication of an occlusion. Since
this occurred immediately after adding air to the ET tube cuff, the therapist should
suspect the possibility of cuff herniation. To rule this suspicion in or out, a suction
catheter should be inserted into the airway to determine if there is an obstruction
near the distal end of the tube.
A 6-minute walk test is used to evaluate
A. a patient's physical stamina and aerobic endurance.
B. pulmonary ventilatory ability.
C. PF ratio.
D. Oxygen desaturation tendency. - ANSWER-A.
A 6-minute walk test (6MWT) is a way of evaluating a patient's physical
performance ability, especially given certain cardiopulmonary limitations. The test

, TMC NBRC ACTUAL EXAM, PRACTICE EXAM
evaluates the distance a person can walk in 6 minutes. This is known as a 6-minute
walk distance (6MWD).
Prior to performing pulmonary function testing on a several patients, a respiratory
therapist is conducting quality control on the pneumotachometer. After injecting a
3.0 L syringe through the pneumotachometer, the therapist notes a measurement
of 2.86 L. Based on this result the therapist should
A. commence testing on patients.
B. replace the pneumotachometer.
C. perform a two-point calibration.
D. calibrate the 3.0-L syringe. - ANSWER-A.
Although the pneumotach should achieve a measurement close to 3.0 L, it is
permissible to use the equipment for patient testing if the result is within +/- 5%
(2.85 L - 3.15 L). In this case, the quality control result is within range, which
suggests that the equipment may be used for patient testing.
How many milliliters of a medication whose strength is 5% is needed to deliver 25
mg of that medication?
A. 1.25 mL
B. 0.50 mL
C. 5.0 mL
D. 125 mL - ANSWER-B.
The first step is to calculate the number of mg/mL in a drug that is at 5% strength.
This is done by multiplying the drug strength by 10. mg/mL = 5% x 10 = 50 mL = 25
mg / 50 mg/mL = 0.50 mL

ASK: While ventilating a patient with a VC ventilator, the respiratory therapist
notices that the ventilator is not delivering the set tidal volume. The therapist
should
A. cycle the ventilator off, then on.
B. obtain an ABG and determine the adequacy of ventilation.
C. remove the ventilator from service ,and perform preoperative test.
D. adjust the tidal volume to compensate. - ANSWER-C.
Should any critical equipment show suspicious signs of malfunction, that
equipment should be immediately removed from service and repaired.
Into which interspace should a chest tube be inserted for the purpose of draining
serosanguinous fluid from the pleural space and for the re-expansion of lung
tissue?
A. 2nd interspace
B. 5th interspace
C. 4th interspace
D. 8th interspace - ANSWER-B.
If fluid is anticipated, chest tubes should be place in the 5th interspace, mid-
axillary line.
The following volume-pressure graphic is observed on a patient who is receiving
VC A/C ventilation. The respiratory therapist should
*Image is a very flat pressure-volume loop*
A. switch to PC ventilation
B. determine average inspiratory plateau pressures

C. change the scale volume axis of the graph
D. determine the patient's static compliance - ANSWER-C.
Although this pressure-volume graphic appears to be 'lying down", which is
usually associated with decreasing pulmonary compliance, closer observation
reveals that the scaling on the volume axis of the graphic is not appropriate. In
other words, the graphic appears as it does due to improper scaling. Once
corrected, the graphic is likely to show normal compliance.
Which of the following conditions could cause a tracheal shift to the right?
1. atelectasis in the left2. sputum consolidation on the right3. pneumothorax on
the right4. lobectomy on the right.
A. 1 and 3 only
B. 1 and 4 only
C. 2 and 4 only
D. 1, 2, and 4 only - ANSWER-C.
Sputum consolidation on the right and a lobectomy on that same side would
cause a tracheal shift to the right. Other options would shift the trachea to the
left.
A respiratory therapist is observing a patient in the intensive care unit (ICU) during
an exacerbation of congestive heart failure. The doctor orders close monitoring of
the hemodynamic status of the patient. The therapist should recommend
A. insertion of a pulmonary artery catheter.
B. a 12-lead ECG every 8 hours.
C. placement of an arterial indwelling catheter.
D. placement of a central line catheter. - ANSWER-A.
