Chapter 8 and 9. Pathophysiology and life span development Questions and Answers For a patient breathing in room air, the EMT would estimate the FiO2 to be: - .21 A patient has a blood pressure of 140/98 mmHg. Which one of the following can the EMT ascertain from this reading? - the afterload is diminished A confused and lethargic 24-year-old has intentionally overdosed on a narcotic medication. His vital signs are: pulse 36, respirations 8, blood pressure 50/20, and SpO2 88% with 15 liters per minute of oxygen. The greatest danger to this patient's well-being is: - decreases cellular perfusion. The patient in anaerobic metabolism is deficient of: - oxygen A slightly confused but conscious 61-year-old female with generalized weakness has a hear rate of 190 beats a minute. She has a history of high blood pressure and diabetes. Her blood pressure is 78/56 mmHg. Which one of the following would best explain the patient's presentation? - Tachycardia You and the critical care transport team are taking a critically ill patient to another hospital. Among many IV infusions and monitors, the patient is also on a ventilator. You note that the FDO2 is set at 0.50. What does this mean? - The provided oxygen concentration is set at 50 percent. Which one of the following measurements indicates a narrowed pulse pressure? 116/82, 108/88, 120/76, 210/ 138 - 108/88 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? - Decreased blood volume available for circulation 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? Diastolic blood pressure of > 200 mmHg Systolic blood pressure of 160 mmHg Blood pressure of 74/26 mmHg Blood pressure of 174/126 mmHg - Blood pressure of 74/26 mmHg Under normal circumstances, carbon dioxide is excreted from the body through the: - Lungs The EMT would best recognize normal cellular metabolism as: - Aerobic Which of the following will affect the ventilation component of the ventilation/perfusion ratio? Blood clot in the pulmonary blood vessels decreased amount of hemoglobin in the blood loss of blood plasma from dehydration infection and pus in the distal airways and alveoli - infection and pus in the distal airways and alveoli The EMT is administering oxygen at 95% through a nonrebreathing face mask. He would document this as an FiO2 of: - 0.95 Which of the following correctly identifies the primary way in which oxygen is transported to the cells? Plasma red blood cells white blood cells plasma proteins - red blood cells A patient has failure of the left side of his heart. Consequently, the blood is backing up into the pulmonary artery and spilling out into the lung tissue, causing him to be short of breath and moderately hypoxic. The EMT should recognize this as a product of: - Increased hydrostatic pressure
