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? -
ANSWER: The patient's lung has an air leak
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: - ANSWER: Reversible 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:
- ANSWER: complete airway obstruction
An unconscious apneic patient with a full stomach cannot be orally intubated in the
emergency room. Which of the following would your recommend be? -
ANSWER: inserting an esophageal-tracheal combitube
While establishing initial ventilatory support settings for a new patient, the most
important consideration is the: - ANSWER: patients size and clinical condition
A male patient has a lower than normal mixed venous O2 content. Which of the
following is the most likely cause of this condition? - ANSWER: Fever
(hyperthermia)

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? - ANSWER: apply 5-10 cm H20 pressure support
What is the approximate duration of flow of an oxygen E-cylinder at 1000 psi
running at 4 L/min? - ANSWER: 70 minutes
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? - ANSWER: increase the suction pressure to -120 mm Hg
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? - ANSWER: a
missing lead
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? - ANSWER: angiography
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: - ANSWER: has smoked within the prior 12-24
hours
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? - ANSWER: decrease in O2 saturation from 91% to 82%

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? - ANSWER:
increased ventilation
A normal vital capacity for a female patient who is five feet three inches tall and
weighs fifty kilograms would be approximately: - ANSWER: 3500 mL
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? - ANSWER: the sensitivity
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? - ANSWER: atrial
fibrillation
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? - ANSWER: Vital Capacity (VC)
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? - ANSWER: Sinus Tachycardia
Which of the following is a prerequisite for discharging a ventilator-dependent
patient to the homecare setting? - ANSWER: whether the patient is stable on low
FiO2s and PEEP
