GRADE!!
The patient's lung has an air leak - 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 - 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?
