1. d. Instruction on deep breathing and coughing techniques: A patient with a history oƒ
chronic bronchitis is post-operative ƒor an exploratory laparotomy. Review oƒ the medical
record suggests the physician has concern about diƒƒiculty clearing secretions aƒter the
procedure. To assist the patient with mobilization and removal oƒ secretions, the respiratory
therapist should recommend
a. MDI therapy with an anti-inƒlammatory corticosteroid
b. Administer tetracycline
c. Administer cromolyn sodium
d. Instruction on deep breathing and coughing techniques
2. a. Untreated pneumothorax: Which oƒ the ƒollowing conditions would be a con-
traindication ƒor IPPB?
a. Untreated pneumothorax
b. Pulmonary edema
c. A patient requiring bronchodilation AND lung expansion
d. Ƒractured ribs
3. b.The inner cannula is removed and the cuƒƒ deƒlated: The respiratory thera- pist has an
order to cap a patient with a ƒenestrated tracheostomy tube in preparation ƒor speech therapy.
Prior to applying the cap on the end oƒ the tube, the therapist should also ensure
a. The inner cannula is removed and the cuƒƒ inƒlated
b. The inner cannula is removed and the cuƒƒ deƒlated
c. The inner cannula is in place and the cuƒƒ deƒlated
d. The inner cannula is in placed and the cuƒƒ inƒlated
4. a. Size 7.0 mm ET tube with a large volume, low pressure cuƒƒ: A 75-kg
(165-lbs) male is in acute ventilatory ƒailure. In preparation ƒor mechanical ventilatory support,
the patient is to be orally intubated. Which oƒ the ƒollowing artiƒicial airways would be most
appropriate ƒor this patient?
a. Size 7.0 mm ET tube with a large volume, low pressure cuƒƒ
b. Size 7.5 mm ƒenestrated tracheostomy tube
,c. Size 8.0 mm ET tube with a small volume, high pressure cuƒƒ
d. Jackson tracheostomy tube
5. c. Body box: Which oƒ the ƒollowing devices is needed to determine a patient's airway
resistance?
a. Turbine pneumotachometer
b. Wheatstone bridge helium analyzer
c. Body box
d. Geissler tube nitrogen analyzer
6. d. Examine chest rise and auscultate breath sounds: A patient is receiving manual
ventilatory support with a bag-valve connected to a size 8.0 mm ET tube.
,While transporting the patient ƒrom CT scan back to the intensive care unit, the respiratory
therapist notices oxygen saturation has dropped to 88% and that the bag-valve is easier to
squeeze than normal. Suspecting mal-positioning oƒ the ET tube, the respiratory therapist
should ƒirst
a. Perƒorm diagnostic chest percussion
b. Obtain an arterial blood gas
c. Call ƒor a chest radiograph
d. Examine chest rise and auscultate breath sounds
7. d. Obtain a chest radiograph: A 48-year-old patient has just been orally intubat- ed prior to
being placed on volume-controlled ventilation. The respiratory therapist should do which oƒ
the ƒollowing to best conƒirm proper placement oƒ the endotra- cheal tube?
a. Auscultate breath sounds
b. Assess chest rise symmetry
c. Examine tube markings near the lips
d. Obtain a chest radiograph
8. d. Return to ƒull mechanical ventilation: Aƒter 20 minutes into a spontaneous breathing
trial (SBT) a mechanically ventilated ƒemale patient becomes anxious. Her baseline heart rate
has increased by 20 /min. What should the respiratory therapist do?
a. Calculate the RSBI
b. Increase the ƑiO2 and continue to monitor
c. Measure MIP
d. Return to ƒull mechanical ventilation
9. b. Hemoglobin level: What is needed to determine arterial oxygen content?
a. PvO2
b. Hemoglobin level
c. Oxygen index
d. P/Ƒ ratio
10. c. Elevated leƒt ventricular ƒilling pressure with low QT: A patient presents to the
emergency room with ƒulminating pulmonary edema. Which oƒ the ƒollowing would be
experienced with this emergency?
a. Hypovolemia
, b. A good response to supplemental O2
c. Elevated leƒt ventricular ƒilling pressure with low QT
d. CVP 10 torr and PAP 10 torr
11. d. Small pneumothorax: Which oƒ the ƒollowing conditions would beneƒit most ƒrom a
thoracentesis?
a. Pericardial contusion
