SCORE A+
The patient's lung has an air leak Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: While establishing initial ventilatory
support settings for a new patient, the most important consideration is the:
Fever (hyperthermia) Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: 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% Correct Answer: 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 Correct Answer: 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 Correct Answer: A normal vital capacity for a female patient who is five feet three
inches tall and weighs fifty kilograms would be approximately:
the sensitivity Correct Answer: 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 Correct Answer: 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) Correct Answer: 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 Correct Answer: 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 Correct Answer: Which of the following is
a prerequisite for discharging a ventilator-dependent patient to the homecare setting?

SCORE A+
a large volume (3 L) calibration syringe Correct Answer: You would need which of the
following equipment in order to calibrate a portable bedside spirometer?
Ventilator-associated pneumonia (VAP) Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: 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 Correct Answer: Defibrillation should be done immediately in
which of the following patient situations?
variable flow control and adjustable I:E ratios Correct Answer: 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 Correct Answer: You are called to
obtain a bedside vital capacity (VC) of 450 ml on a 122 lb female patient receiving ventilatory
support in the CMV mode. Which of the following can you draw from this finding?
hyperventilation/hypocapnia Correct Answer: Which of the following is the most common
problem encountered when applying assist-control mode during ventilation?
flowmeter-humidifier connection for leaks Correct Answer: 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 Correct Answer: Which of the following would cause an increase in a patient's
peak airway pressure while receiving volume control ventilation?
