FCC EMT CH 8 Exam Test Questions And
Answers Verified 100% Correct
What is the best description of the ventilation/perfusion (V/Q) ratio? - ANSWER- The
ability of the body to exchange gases across the alveolar capillary membrane
A chronically elevated afterload increases the patient's chance for developing which
pathological condition? - ANSWER- Heart failure
A patient with a severe infection is very sick. Circulating toxins from bacteria in his blood
have decreased his systemic vascular resistance (SVR). Which blood pressure change
would the EMT correlate to this condition? - ANSWER- Blood pressure of 64/26 mmHg
Under normal circumstances, carbon dioxide is excreted from the body through the: -
ANSWER- Lungs
When a patient has a narrowed pulse pressure, what is occurring? - ANSWER- The
blood vessels are constricting
A patient has a pulmonary condition known as asthma that results in significant
bronchoconstriction. If this patient is found to be hypoxic during an asthma attack, which
type of disturbance is most likely causing the hypoxia? - ANSWER- Ventilation
disturbance
Perfusion is best described as: - ANSWER- Delivery of essential products and nutrients
to the cell for its use
Which statement is true of a patient who relies on the hypoxic drive to breathe? -
ANSWER- The respiratory rate is set according to the level of O2 in the body
What is the best description of the ventilation/perfusion (V/Q) ratio? - ANSWER- The
ability of the body to exchange gases across the alveolar capillary membrane
A patient's brain cells are undergoing anaerobic metabolism. As a result, those cells: -
ANSWER- Are becoming dysfunctional in an environment that is increasingly acidic
A patient has failure of the left side of his heart. Consequently, his blood is backing up
into the pulmonary artery and seeping into the lung tissue, causing the patient to be
short of breath and moderately hypoxic. The EMT should recognize this condition as a
product of: - ANSWER- Increased hydrostatic pressure
, A 20-year-old female patient has called 911 for chest pain. On scene, you find that she
has shallow breathing with an SpO2 reading of 91% on room air. She states she was in
a car crash yesterday and diagnosed in the hospital with broken ribs. Her pain is right
where the ribs are broken, and she rates the pain as a 10/10. Breath sounds are present
bilaterally. In this situation, the EMT should attribute the hypoxia to which cause? -
ANSWER- Pain from rib injury prevents full expansion of the chest cage
A patient has been shot three times in the abdomen and has massive internal
hemorrhage and blood loss. Which treatment will give this patient the best chance at
survival? - ANSWER- Stopping the bleeding
While completing some clinical time in the hospital for his EMT class, an EMT student
observed a patient being administered an IV fluid with a high oncotic pressure. Once
this fluid is in the patient's body, the EMT student would expect which action to occur? -
ANSWER- Fluid from the tissues will move into the bloodstream
The EMT would most likely see a narrowed pulse pressure in a patient who: -
ANSWER- Is bleeding internally
A patient's SpO2 increased from 89% to 95% after he received a bronchodilating drug
for his asthma. Where did the patient's problem most likely originate? - ANSWER-
Ventilation portion of the V/Q ratio
An unresponsive patient with a pulse is breathing with very shallow respirations at a rate
of 6 breaths per minute. Which intervention would be most beneficial for this patient? -
ANSWER- Positive pressure ventilation with a rate of 12 breaths/min and a tidal volume
of 500 mL
A 35-year-old male patient is lethargic and dehydrated after working at a construction
site for 12 hours on a very hot day. You obtain the following vital signs: pulse, 136;
respirations, 22 breaths/min; blood pressure, 102/88 mmHg; and SpO2, 100% with
supplemental oxygen. As a knowledgeable EMT, you would recognize: - ANSWER-
Elevated heart rate to increase cardiac output
For a patient who relies on the hypoxic drive to breathe, the respiratory rate will
increase when: - ANSWER- O2 levels decrease
Failure of the sodium-potassium pump can result in: - ANSWER- Cellular damage,
swelling, and rupture
What is the protective mechanism underlying a narrowed pulse pressure? - ANSWER-
Maintain an adequate blood pressure for perfusion
