106. End-tidal carbon dioxide (ETCO2) is defined as the:A.maximal concentration of CO2at the end of an exhaled breath.
B.maximum amount of CO2that remains in the lungs at all times.C.total amount of CO2that remains in the lungs between breaths.D.amount of CO2that a person breathes in during a single inhalation.107. A low ETCO2reading, as measured by capnography, would MOST likely be observed if:A.a patient in cardiac arrest is receiving high-quality CPR.B.an endotracheal (ET) tube is correctly placed in the trachea.C.there is an absence or decrease in the level of CO2in the lungs.D.the cells produce large amounts of CO2and return it to the lungs.108. Which of the following would the EMT most likely NOT perform on a responsive patient with a headacheand no apparent life-threatening conditions?A.focused secondary assessmentB.assessment of oxygen saturationC.systemic head-to-toe examinationD.noninvasive blood pressure monitoring109. The goal of the full-body scan that is performed during the secondary assessment is to:A.detect and treat all non–life-threatening injuries.B.assess only the parts of the body that are injured.C.definitively rule out significant internal injuries.D.locate injuries not found in the primary assessment.110. A full-body scan should be performed on:A.stable patients who are able to tell you exactly what happened.B.all patients with traumatic injuries who will require EMS transport.C.responsive medical patients and patients without a significant MOI.D.patients with a significant MOI and unresponsive medical patients.111. You respond to the scene of a motor vehicle collision. Upon arrival, you find the driver, a young female,sitting on the curb. She is confused, is in obvious respiratory distress, and has pale, moist skin. As yourpartner manually stabilizes her head, you perform a primary assessment. After performing any immediatelivesaving treatment, you should:A.perform a rapid scan of her entire body and prepare for immediate transport.B.assess her vital signs, secure her to a backboard, and transport her immediately.C.fully immobilize her spine, load her into the ambulance, and assess her vital signs.D.identify the specific areas of her injuries and focus your assessment on those areas.112. When performing a full-body scan on a trauma patient, you note the presence of Battle’s sign. This isdefined as:A.unequal pupils.B.bruising behind the ear.C.swelling to the orbital area.D.fluid drainage from the nose.113. A decrease in the blood pressure may indicate:A.a loss of vascular tone.B.arterial constriction.C.increased blood volume.D.forceful cardiac contraction.114. The pressure exerted against the walls of the artery when the left ventricle contracts is called the:A.blood pressure.
