A 77-year-old male patient is scheduled to undergo open heart surgery. Preoperative
spirometry results show the patient's FEV1 is 80% of predicted and the FEV1/FVC is 83%,
indicating
A. high risk for postoperative pulmonary complications.
B. low risk for postoperative pulmonary complications.
C. the patient has obstructive lung disease.
D. the patient has restrictive lung disease
B. low risk for postoperative pulmonary complications.

AND STUDYGUIDE
The FEV1 and FEV1/FVC values are within normal ranges. The patient should be able to deep
breathe and cough after surgery.
Which of the following clinical observations is most commonly associated with right heart
failure?
A. tracheal deviation
B. peripheral edema
C. muscle wasting
D. skin flushing
B. peripheral edema
Right heart failure inhibits venous return and results in edema in the periphery.
While testing the proper function of a flow-inflating bag, a respiratory therapist notes the bag
does not fully inflate with occlusion of the patient connector. Which of the following may be
the cause of the problem?
A. malfunctioning inlet valve
B. excessive oxygen flow
C. open-flow control valve
D. missing oxygen reservoir
C. open-flow control valve
The flow control valve in conjunction with the gas flow into the bag regulates the filling of the
bag. With the flow control valve open, the gas going into the bag will immediately leave the
bag through the open-flow control valve.

To determine the need for ventilatory support in a patient with Guillain-Barré syndrome, which
of the following clinical information should be obtained?
A. chest radiograph and V̇O2max
B. V̇O2max and MIP
C. MIP and vital capacity
D. vital capacity and chest radiograph
C. MIP and vital capacity
MIP is an indication of respiratory muscle strength. Vital capacity provides information
regarding respiratory reserve. Both provide data about the need for ventilatory support in a
patient with neuromuscular disease.
Apnea monitoring should be used for an infant during
A. night time and breastfeeding.
B. naps and night time.
C. breastfeeding and bathing.
D. bathing and naps.
B. naps and night time
An apnea monitor is indicated when an infant is asleep or when not being observed;
therefore, it should be used during naps and at night.
After a transcutaneous electrode is attached to a patient's skin, a respiratory therapist should
wait a few minutes for the values to stabilize. This wait is associated with
A. capillary dilatation.
B. electrode calibration.
C. barometric pressure equilibration.
D. cerebral blood perfusion.

A. capillary dilatation.
The site must be heated for 2-5 minutes to facilitate capillary dilatation. Once dilatation
occurs, transcutaneous values will stabilize.
A 44-year-old patient presents to the ED with diabetic ketoacidosis. Which of the following
respiratory patterns is most consistent with this diagnosis?
A. irregular breathing with periods of apnea
B. regular, slow, deep breathing
C. rapid, deep breathing
D. slow, shallow breathing
C. rapid, deep breathing
To attempt to compensate by blowing off CO2, there is an increase in rate and depth of
breathing. This is called Kussmaul's breathing and is the result of diabetic ketoacidosis.
A respiratory therapist is assisting a physician perform a tracheotomy on a patient who is
receiving PC ventilation. After the stoma is opened and the tracheostomy tube is inserted, the
therapist observes increased heart rate, decreased exhaled tidal volume, and distant breath
sounds over the right chest. This information is most indicative of a
A. circuit leak.
B. right pneumothorax.
C. kink in the ventilator circuit.
D. right mainstem intubation.
B. right pneumothorax.
Keeping the current invasive procedure in mind, the diminished breath sounds over the
affected area and an increased heart rate are consistent with a pneumothorax.
