questions and verified answers (complete solutions)
A+ 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
, 3|Page
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?
