Following thoracotomy, a patient receives incentive spirometry therapy Q2H. Her
breath sounds are diminished in the bases of the lungs with scattered crackles.
The patient's inspiratory capacity has decreased over the past 2 days. A chest
radiograph indicates thin-layered basilar densities. Which of the following has
most likely occurred?
A. Atelectasis
B. Pneumonia
C. Pulmonary edema
D. Consolidation -ANS-A. Atelectasis
A balloon-tipped, flow-directed catheter is positioned in the pulmonary artery
with the balloon deflated. Which of the following pressures will be measured by
the distal lumen?
A.CVP
B.PAP
C.PCWP
D.MAP -ANS-B.PAP

A patient has been intubated with a naso-tracheal tube and is being manually
ventilated. As the respiratory therapist ventilates the patient, he notices that
there is no chest movement, minimal breath sounds and air escaping from the
mouth as the bag is squeezed. A chest x-ray has determined that the
endotracheal tube is in the correct position. What is the most likely cause of this
situation?
A. The tube is in the esophagus.
B. The patient has developed a tracheoesophageal fistula from the intubation
process.
C. The cuff ruptured during intubation.
D. The cuff has herniated over the end of the tube. -ANS-C. The cuff ruptured
during intubation.
The respiratory therapist calibrates a spirometer and checks the volume with a
3.0 liter super syringe. The volumes recorded are: 2.85 L, 2.8 L, and 2.8 L. Based
upon the information obtained which of the following is a correct statement?
A. Another syringe needs to be used
B. Spirometer is accurate
C. The plunger was advanced too slowly
D. Spirometer may have a leak -ANS-D. Spirometer may have a leak
Range of accuracy- 2.895-3.105L
An optimal PEEP study is initiated for a patient receiving mechanical ventilation.
The respiratory therapist initiates PEEP of 10 cm H2O for 20 minutes with no
adverse effects. The PEEP is increased to 15 cm H2O and the patient's heart rate
,3|Page
rises significantly with a severe fall in the blood pressure. Based upon the above
information, the therapist should conclude that the patient is suffering from
A. peripheral vasoconstriction.
B. hypovolemia.
C. increased venous return.
D. increased SVR. -ANS-B. hypovolemia.
Which of the following is an indication for high frequency jet ventilation?
A. Bronchopleural fistula
B. Wilson Mikity syndrome
C. Necrotizing lesion of right lung
D. Centrilobular emphysema -ANS-A. Bronchopleural fistula
A 43-year-old female patient undergoes a total abdominal hysterectomy. The
patient arrives in the Post Anesthesia Care Unit obtunded with minimal response
to painful stimulus. What treatment should the respiratory therapist recommend
for this patient?
A. Initiate assisted ventilation
B. Insert oropharyngeal airway
C. Obtain positron emission tomography
D. Initiate noninvasive capnography -ANS-B. Insert oropharyngeal airway
A 44-week gestational age infant is delivered via C-section and is gasping,
grunting, and has tachycardia and tachypnea. At one minute his Apgar score is 4
and at 5 minutes the score is 5. The infant is most likely suffering from
, 4|Page
A.transient tachypnea of the newborn.
B.meconium aspiration.
C.bronchopulmonary dysplasia.
D.apnea of prematurity. -ANS-B.meconium aspiration. Pay
What is the normal VD/VT ratio for a patient breathing room air?
A.5 - 15%
B.20 - 40%
C.45 - 55%
D.65 - 75% -ANS-B.20 - 40%
A heat moisture exchanger is indicated for humidification in which of the
following situations?
A.Mechanical ventilation in a long-term care facility.
B.Transport to a tertiary care center.
C.Patient with tenacious secretions.
D.Delivery of aerosolized bronchodilators. -ANS-B.Transport to a tertiary care
center.
All of the following could cause a patient's right-hemidiaphragm to be elevated,
EXCEPT
A.right lower lobe atelectasis.
B.right side hyperlucency, absent vascular markings.
