Q21Decide if the following statement is true:<br/><br/>'Endotracheal intubation causes a more significant vagal reaction in infants than children and adults.'
✓ Correct answer: B. True
Endotracheal intubation causes a more significant vagal reaction in infants than children and adults, as they may experience bradycardia with direct laryngeal stimulation.
Q22The signs and symptoms of traumatic retroperitoneal Hematoma are?
✓ Correct answer: D. All of the above
In terms of the diagnosis, the signs and symptoms of traumatic retroperitoneal hematoma include abdominal pain, abdominal mass, abdominal distension , severe back and lower quadrant pain and femoral neuropathy further diagnosis is confirmed by CT and Ultrasonography.
Q23The fourth step in a pediatric exam, palpate, involves:
✓ Correct answer: B. Touching
Palpation should be done with the abdominal wall muscles relaxed. The abdomen should be completely exposed. To help the abdominal wall muscles relax before palpation, the child should be instructed to inhale deeply and exhale fully.
Q24You are working as EMS paramedical an your EMS system uses rapid transport system and simple triage for triage of patients at multiple casualty incident you will include which one of the following in your triage assessment for determination of patients that will receive emergency care?
✓ Correct answer: D. Perfusion and respiratory status of patient
Perfusion status and respiration of patient will be used in triage assessment for determination of patients that will receive emergency care.
Q25The primary survey includes the trauma care ABCDEs. What does the B in ABCDE stand for?
✓ Correct answer: A. Breathing and ventilation
The letter B represents breathing and ventilation. If breathing is insufficient, assisted ventilation must be performed with or without a barrier device.
Q26A 20 year old patient is having blunt abdominal trauma to the left side of the lower abdomen which one the following organ is not injured/least injured?
✓ Correct answer: A. Liver
Except liver all of the above are retroperitoneal organs and the liver is in the right side so the chances of liver injury is least.
Q27Which of the following is an indication for gastric lavage in patients who have ingested a toxin or who have overdosed on drugs?
✓ Correct answer: B. Within 1 hour of ingestion.
Gastric lavage may be indicated for patients who have ingested a potentially lethal amount of drug or toxin within the preceding 1 hour. Beyond 1 hour, gastric lavage and/or activated charcoal are ineffective.
Q28A 26 year - old woman is brought to the Emergency Department after being involved in a motor vehicle crash. She is 30 weeks pregnant. She was restrained with a lap and shoulder belt, and an airbag deployed. <br/><br/>Which one of the following statements best describes the risk of injury?
✓ Correct answer: D. The risk of premature fetal delivery and death is reduced by the use of restraints.
<strong>BLUNT INJURY</strong><br/><br/>Th abdominal wall, uterine myometrium, and amniotic fluid act as buffers to direct fetal injury from blunt trauma. The presence of external contusions and abrasions of the abdominal wall, are signs of possible blunt uterine injury. Nonetheless, fetal injuries may occur when the abdominal wall strikes an object, such as the dashboard or steering wheel, or when a pregnant patient is struck by a blunt instrument. Indirect injury to the fetus may occur from rapid compression, deceleration, the contrecoup effect, or a shearing force resulting in abruptio placentae.<br/><br/>Compared with restrained pregnant women involved in collisions, unrestrained pregnant women have a higher risk of premature delivery and fetal death. The type of restraint system affects the frequency of uterine rupture and fetal death. Using a lap belt alone allows forward flexion and uterine compression with possible uterine rupture or abruptio placentae. A lap belt worn too high over the uterus may produce uterine rupture because it transmits direct force to the uterus on impact. <br/><br/>What*Using shoulder restraints in conjunction with a lap belt reduces the likelihood of direct and indirect fetal injury, </strong>presumably because the shoulder belt dissipates deceleration force over a greater surface area and helps prevent the mother from flexing forward over the gravid uterus. Therefore, in the overall assessment it is important to determine the type of restraint device worn by the pregnant to determine the type of restraint device worn by the pregnant patient, if any. The deployment or airbags in motor vehicles does not appear to increase pregnancy-specific risks.
Q29Regarding the transfer of trauma patients, you should remember the acronym ABC-SBAR. <br/><br/>What does the C in ABC-SBAR mean?
✓ Correct answer: C. Circulation
The C in ABC-SBAR stands for circulation. All circulation problems must be identified, and interventions must be performed.
Q30Which one of the following statements concerning intraosseous infusion is TRUE?
✓ Correct answer: D. Aspiration of bone marrow confirms appropriate positioning of the needle.
Aspiration of bone marrow confirms that the needle tip is in the bone marrow. <br/><br/>Note: Any fluid that can be infused intravenously can also be infused intraosseously. Peripheral IV is the preferred route for volume resuscitation in small children. Intraosseous infusion should only be utilized until an alternative parenteral route can be established so that the risk of infection is minimized. <br/><br/>Swelling in the soft tissues around the intraosseous site is a reason to discontinue infusion at that site.
