TEST BANK For Prehospital Emergency Care 11th Edition ByJoseph J. Mistovich, Keith J. Karren
You are caring for a 66-year-old male who is severely dehydrated. Given this
condition, you would recognize which of the following related to the cardiovascular
system? - ANSWER:Decreased blood volume available for circulation
Which of the following statements about chemoreceptors in the human body is
true? - ANSWER:The peripheral chemoreceptors are more sensitive to oxygen than
carbon dioxide.
In the hospital, a patient was administered an IV fluid with a high oncotic pressure.
Once in the body, the EMT would expect which one of the following actions? -
ANSWER:Fluid from the tissue to move into the bloodstream
Which one of the following best describes minute ventilation? - ANSWER:Amount of
air moved into and out of the lungs in one minute
Under normal circumstances, carbon dioxide is excreted from the body through the:
- ANSWER:lungs.
The patient in anaerobic metabolism is deficient of: - ANSWER:Oxygen
The EMT would recognize which of the following vital signs as most likely to cause
left ventricular failure? - ANSWER:Chronically elevated diastolic pressure between
120 and 140 mmHg
A patient with a severe infection is very sick. Circulating toxins from bacteria in his
blood have decreased his systemic vascular resistance (SVR). Which of the following
would the EMT correlate to this condition? - ANSWER:Blood pressure of 74/26
mmHg
For the patient with a narrowed pulse pressure, which one of the following is
occurring? - ANSWER:The blood vessels are constricting.
Which of the following medical conditions would impair a patient's respiratory status
by directly damaging the central chemoreceptors? - ANSWER:Brainstem stroke
Paramedics have administered a medication to a patient in heart failure. The
medication specifically causes the veins to enlarge, thus decreasing the amount of
blood coming back to the heart for pumping. The EMT would recognize this action
as: - ANSWER:Preload
, On scene, a 43-year-old male states that he has a history of liver failure and does not
produce enough of the protein albumin. Given this condition, which one of the
following would you expect? - ANSWER:Swelling of the extremities and abdomen
A patient who is weak informs you that she has a history of her "iron being too low."
This should concern the EMT because iron is needed to: - ANSWER:carry oxygen
throughout the body.
Perfusion is best described as: - ANSWER:delivery of essential products and nutrients
to the cell for its use.
What is the protective mechanism underlying a narrowed pulse pressure? -
ANSWER:Maintain an adequate blood pressure for perfusion.
A patient with asthma is extremely short of breath and hypoxic. Related to the
ventilation/perfusion ratio (V/Q), the EMT would recognize the problem lying in: -
ANSWER:inadequate oxygen in the alveoli.
When a healthy person has a sudden increase in blood pressure, which one of the
following will occur? - ANSWER:Baroreceptors will signal the brain to decrease the
heart rate.
Which of the following is required for normal perfusion to occur? -
ANSWER:Adequate breathing, sufficient red blood cells, good heart function
A patient who has lost 1 liter of blood is conscious with a patent airway, but his
extremities are pale and cold to the touch. Vital signs are pulse 130, respiration are
22 and adequate, blood pressure is 74/56, and SpO2 is 95% on room air. Which one
of the following is most needed by this patient to increase perfusion to the cells? -
ANSWER:Increased number of red blood cells and plasma volume
Assessment of a hypoxic patient with a history of lung disease reveals him to be
using well-developed accessory muscles to exhale. As an EMT, you should recognize
that the patient: - ANSWER:is using energy to exhale and is in danger of respiratory
failure.
The EMT is administering oxygen at 95% through a nonrebreathing face mask. He
would document this as a FiO2 of: - ANSWER:0.95.
Which one of the following measurements indicates a narrowed pulse pressure? -
ANSWER:108/88
The body will compensate for a decrease in cardiac output by: - ANSWER:increasing
systemic vascular resistance.
Which one of the following conditions would most likely account for an elevated
carbon dioxide level in a patient's body? - ANSWER:Lung disease
