⩥ Reversible airway obstruction. 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. 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. 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. Answer: While establishing initial
ventilatory support settings for a new patient, the most important
consideration is the:
⩥ Fever (hyperthermia). 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. 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. 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. 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. 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. 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. 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%. 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. 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. 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. 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. 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). 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. 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. Answer: Which
of the following is a prerequisite for discharging a ventilator-dependent
patient to the homecare setting?
⩥ a large volume (3 L) calibration syringe. Answer: You would need
which of the following equipment in order to calibrate a portable bedside
spirometer?
⩥ Ventilator-associated pneumonia (VAP). Answer: A physician orders a
blind bronchoalveolar lavage procedure for a patient in intensive care
