VERSIONS WITH A STUDY GUIDE 2024
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?
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 unit. What is the
most likely potential diagnosis that the doctor is trying to confirm with this procedure?
