FCC EMT CH 8 TEST QUESTIONS WITH ALL CORRECT DETAILED ANSWERS

FCC EMT CH 8 TEST QUESTIONS WITH ALL CORRECT DETAILED ANSWERS A patient with liver disease has a low platelet count. Which additional finding would the EMT directly correlate to this condition? - ANSWER- Excessive bruising to arms Which situation would most likely cause a patient to have a simple episode of syncope (fainting)? - ANSWER- Parasympathetic stimulation You are caring for a 66-year-old male patient who is severely dehydrated. How does severe dehydration affect the cardiovascular system? - ANSWER- It decreases the blood volume available for circulation What is the result of an opening developing that allows air into the space between the visceral and parietal pleura of the thorax? - ANSWER- Progressive collapse of the lung What blood pressure change as most likely to cause left ventricular failure? - ANSWERChronically elevated diastolic pressure between 120 and 140 mmHg What is the primary way in which oxygen is transported to the cells? - ANSWER- Red blood cells For cells to undergo the process of aerobic metabolism, the cells require: - ANSWEROxygen and glucose A patient with a temperature of 105.4°F is experiencing systemic vasodilation. Which finding would be consistent with this condition? - ANSWER- Decreased blood pressure A patient is hemorrhaging internally within his colon, which in turn is impairing perfusion to the cells of his body. Aside from the bleeding, the patient has no other problems. In this scenario, the problem impairing adequate perfusion would be: - ANSWERDecreased blood volume A patient has a blood pressure of 140/98 mmHg. What can the EMT ascertain from this reading? - ANSWER- The afterload is increased Which condition must be met for carbon dioxide to move from the cell to the bloodstream? - ANSWER- The perfusing blood must be low in carbon dioxide When cells undergo normal metabolism in the body, which byproduct(s) is (are) produced? - ANSWER- Heat, carbon dioxide, and water A patient with a high fever has an accelerated metabolism and is producing abnormally large amounts of carbon dioxide at the cellular level. To compensate for this effect, what will occur? - ANSWER- Increased respiratory rate 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 as related to: - ANSWER- Inadequate oxygen in the alveoli A patient who is hypoxic has a pulmonary disease that involves low lung compliance. With this condition, you realize that: - ANSWER- Ventilation with a bag-valve mask will likely require more effort Which blood pressure reading best indicates a narrowed pulse pressure? - ANSWER108/88 mmHg What is required for normal perfusion to occur? - ANSWER- Adequate breathing, sufficient numbers of red blood cells, and sufficient heart function What is the primary stimulus to breathe in human beings without pulmonary diseases? - ANSWER- Level of CO2 in the body Why would a drop in the oxygen content of the blood stream cause an increase in the patient's blood pressure? - ANSWER- Sympathetic stimulation of the cardiovascular system improves oxygen delivery to the brain and tissues
