The patient's lung has an air leak
You are called to the emergency department to help care for a patient who was in a vehicle accident
and has chest injuries including broken ribs. Crepitations are felt while palpitating the patient's neck.
What is most likely the cause of this?
Reversible airway obstruction
A forced expiratory measurement obtained after the administration of a bronchodilator shows an
increase in FEV1 from 60% to 80% of predicted. This indicates a:
complete airway obstruction
During capnography monitoring of a mechanically ventilated patient, you note that the end-tidal
PCO2 (PetCO2) has dropped to 0 mm Hg. This finding may indicate:
inserting an esophageal-tracheal combitube
An unconscious apneic patient with a full stomach cannot be orally intubated in the emergency room.
Which of the following would your recommend be?
patients size and clinical condition
While establishing initial ventilatory support settings for a new patient, the most important
consideration is the:
Fever (hyperthermia)
A male patient has a lower than normal mixed venous O2 content. Which of the following is the most
likely cause of this condition?
apply 5-10 cm H20 pressure support
You are trying to wean an alert intubated patient off full ventilatory support using the CPAP protocol
with 40% O2. Early in the initial effort her respiratory rate increases from 24 to 30/min and you start
to observe some use of her accessory muscles while breathing. Which of the following would be your
first action at this time?
70 minutes
What is the approximate duration of flow of an oxygen E-cylinder at 1000 psi running at 4 L/min?
increase the suction pressure to -120 mm Hg
While using a Yankauer device to suction an adult patient, you are unable to remove thick secretions.
The regulator attached to the oropharyngeal suctioning device displays a reading of -70 mm Hg.
Which of the following actions should you take at this time?
a missing lead
While setting up a 12-lead EKG on a patient, you are unable obtain any electrical signal. The batteries
are fully charged and the device was able to power-on. The most likely cause of this problem is which
of the following?
,angiography
Which of the following imaging procedures is used to evaluate the arteries for abnormalities such as
aneurysm, atherosclerosis, embolism, occlusion, stenosis, thrombosis, trauma, or vasculitis?
has smoked within the prior 12-24 hours
You obtain an expired carbon monoxide (CO) reading of 18 ppm on a COPD patient participating in a
pulmonary rehabilitation program. Based on this finding, you can conclude that the patient:
decrease in O2 saturation from 91% to 82%
While monitoring a patient during a spontaneous breathing trial, which of the following observations
would cause you to stop the trial and return the patient to ventilatory support?
increased ventilation
Your patient is receiving volume control A/C ventilation. She has become increasingly agitated and the
end-tidal CO2 has decreased from 38 to 27 torr over the last 3 hours. Which of the following is most
likely the cause?
3500 mL
A normal vital capacity for a female patient who is five feet three inches tall and weighs fifty kilograms
would be approximately:
the sensitivity
An asthmatic patient is struggling to initiate inspiration on a ventilator operating in the assist-control
mode. Which of the following ventilator settings would you first check in order to resolve of this
problem?
atrial fibrillation
On inspection of a patient's EKG strip, you note that there are no identifiable P waves; rapid irregular
undulations of the isoelectric line; and an irregular ventricular rhythm. In addition, the precordial
cardiac rate is greater than the peripheral pulse rate. What is the most likely problem?
Vital Capacity (VC)
Which of the following is the best bedside measurement for assessing the integrated function of the
respiratory muscles and mechanical properties of the lungs and thorax?
Sinus Tachycardia
While inspecting an EKG rhythm strip from an adult patient, you note the following: rate of 148;
regular rhythm; normal P waves, P-R intervals, and QRS complexes. What is most likely the problem?
whether the patient is stable on low FiO2s and PEEP
Which of the following is a prerequisite for discharging a ventilator-dependent patient to the
homecare setting?
a large volume (3 L) calibration syringe
, You would need which of the following equipment in order to calibrate a portable bedside
spirometer?
Ventilator-associated pneumonia (VAP)
A physician orders a blind bronchoalveolar lavage procedure for a patient in intensive care unit. What
is the most likely potential diagnosis that the doctor is trying to confirm with this procedure?
croup
An AP X-ray of a 4-year-old child with wheezing and stridor shows an area of prominent subglottic
edema, but the lateral neck X-ray appears normal. The most likely problem is?
sternocleidomastoid muscles used at rest
If noted on inspiration, which of the following respiratory signs of an adult patient would be
considered abnormal?
between the 2nd and 4th thoracic vertebra
While reviewing the chest X-ray of a 30-year-old male receiving ventilatory support via an oral
endotracheal tube. To assure proper placement of the tube, you would look for its tip to be
positioned
pulseless ventricular tachycardia
Defibrillation should be done immediately in which of the following patient situations?
variable flow control and adjustable I:E ratios
An intubated adult 65-year-old male patient with severe expiratory airway obstruction requires
ventilatory support. Which of the following capabilities would be most important in selecting a
ventilator for this patient?
the patient cannot sustain prolonged spontaneous ventilation

ventilatory support in the CMV mode. Which of the following can you draw from this finding?
hyperventilation/hypocapnia
Which of the following is the most common problem encountered when applying assist-control mode
during ventilation?
flowmeter-humidifier connection for leaks
A bubble humidifier is not bubbling during oxygen therapy, despite the flowmeter set and running at
5 L/min. Which of the following should you check?
bronchospasm
Which of the following would cause an increase in a patient's peak airway pressure while receiving
volume control ventilation?
inspissated secretions
