EMT Chapter 8 Test
Which condition is recognized as one that will affect the ventilation
component of theventilation/perfusion ratio?
Infection and pus in the distal airways and alveoli
When cells undergo normal metabolism in thebody, whichbyproduct(s)
is(are) produced?
heat, carbon dioxide and water
Assessment of a hypoxic patient who is showing signs of fatigue and has
a history of lung disease reveals him to be usingwell-developed
accessory muscles to exhale. As anEMT, you should recognize that the
patient:
is using energy to exhale and is in danger of respiratory failure
A patient with a low blood sugar is unresponsive with snoring
respirations. His breathing is labored and his pulse is rapid and weak.
Examination of the skin reveals it to be cool and diaphoretic. Your
partner informs you of the following vitalsigns: pulse,120; respirations,
18breaths/min; bloodpressure, 132/60mmHg; and SpO2 at84% on
room air. Which action would you performfirst?
Perform a head-tilt chin-lift.
Which condition is most likely to causeacidosis?
depressed respirations
Which statement is true of a patient who relies on the hypoxic drive to
breathe?
The respiratory rate is set according to the level of O2 in the body.
, What situation could impair apatient's respiratory status by directly
damaging the central chemoreceptors of thebody?
brainstem stroke or injury
You and the critical care transport team are taking a critically ill patient to
another hospital. Among many IV infusions andmonitors, the patient is
also on a ventilator. You note that the FDO2 is set at 0.50. What does
thismean?
The provided oxygen concentration is set at 50 percent.
For a patient who is acutelybleeding, what is the immediate response of
the humanbody?
Vasoconstriction caused by the sympathetic nervous system
We have an expert-written solution to this problem!
What is the best description of minuteventilation?
amount of air move into and out of the lungs in one minute
While completing some clinical time in the hospital for his EMTclass, an
EMT student observed a patient being administered an IV fluid with a
high oncotic pressure. Once this fluid is in thepatient's body, the EMT
student would expect which action tooccur?
fluid from the tissues will move into the bloodstream
Onscene, a43-year-old male states that he has a history of liver failure
and does not produce enough of the protein albumin. Given this
condition, whichfinding(s) would youexpect?
Swelling of the extremities and abdomen
A patient with a severe infection is very sick. Circulating toxins from
bacteria in his blood have decreased his systemic vascular resistance
