(2ml/kg of inspired tidal volume) They conduct airflow towards gas exchange units. Crycothyroid membrane - CORRECT ANSWER -between thyroid and cricoid, avascular structure that connects the thyroid and cricoid cartilage. Site of CRiCOTHYROTOMY - an emergency opening of the airway. A PaCO2 greater than 45 mmHg indicates: A. Metabolic acidosis. B. Metabolic alkalosis. C. Respiratory acidosis. D. Respiratory alkalosis. - CORRECT ANSWER -C. Respiratory acidosis PaCO2 normal range - CORRECT ANSWER -35-45 mm Hg Less than 35 likely means hyperventilation Tracheal deviation AWAY from the affected side, decreased breath sounds, and hyperresonance... What's happening? - CORRECT ANSWER -Tension pneumothorax In a tension pneumothorax tracheal deviation goes in what direction? - CORRECT ANSWER -AWAY from affected side. Normal mean pulmonary artery pressure - CORRECT ANSWER -10-20 mmHg Pulmonary hypertension is a mean PA pressure greater than... - CORRECT ANSWER -
(PAm) greater than 20 Primary pulmonary hypertension - CORRECT ANSWER -Idiopathic genetic disorder caused by abnormal structure of the pulmonary blood vessels Name three causes of secondary pulmonary hypertension.. - CORRECT ANSWER -1. Passive PH - the result of back pressure. Mitral Stenosis, LV systolic failure. 2. Active PH - Constriction of the pulmonary circuit Increased volume in pulmonary circuit (i.e. congenital heart disease) 3. Obstruction as in Chronic recurrent PE TNP of the Pregnant patient - CORRECT ANSWER -Resuscitation priorities are the same. The best way to take care of the baby is to take care of mama Mechanisms of injury and biomechanics the most common cause of maternal injury is... - CORRECT ANSWER -Blunt trauma caused by MVC. Second is BT caused by falls, 3rd is violence fetal distress is an early sign of maternal distress... Why? - CORRECT ANSWER -
Catecholamine mediated vasoconstriction resulting from blood loss shunts blood away from the fetus to the mom. Fetal hypo perfusion is evidenced by.... - CORRECT ANSWER -Fetal tachycardia (140 to 160+) and fetal bradycardia The FRC in a pregnant patient is.... - CORRECT ANSWER -Reduced by the gravid uterus lifting the diaphragm. chest tube placement in a pregnant patient is 1 -2 spaces higher - CORRECT ANSWER -
Because of the lifted diaphragm What is the cause of physiological anemia in pregnant patients? - CORRECT ANSWER -Hemodilitional anemia occurs. Plasma volume increases 30 -50%. Preterm Labor (PTL) - CORRECT ANSWER - abruptio placentae - CORRECT ANSWER -premature separation of the placenta from the uterine wall On a pregnant patient... - CORRECT ANSWER -Chest compressions must be higher on the sternum. Any preg patient 20 weeks pregnant or more with a uterus above the umbilicus should have the uterus left laterally displaced during compressions to avoid aortocaval compression. A 15 degree tilt of the long board or lateral displacement. What is the Maternal Fetal Triage Index? - CORRECT ANSWER -A valid reliable 5 level triage tool that may assist in the triage of obstetric trauma patients. Displacing the uterus off the vena cava can improve CO by - CORRECT ANSWER -
approximately 30%! Continuous fetal monitoring is recommended... - CORRECT ANSWER -for all pregnant patients 20 or more weeks gestation... or (uterus above belly button). Fundal height measurement - CORRECT ANSWER -equals the approximate gestational age in weeks, until week 32. Belly button is 20 weeks Height of last rib is 26 weeks costal margin is 36 weeks Any fundal height indicating 23 or more weeks... - CORRECT ANSWER -at the last rib and above is consistent with a viable fetus.

What is the serum lab test that detects fetal red cells in the maternal circulation? - CORRECT ANSWER -Kleinhauer Bette KB serum test. This lab is used to determine if hemorrhage of fetal blood through the placenta and into maternal circulation. KB test is an important detector of abruptio placentae, preterm labor and need to administer Rh negative globulin when mom is Rh negative and fetus is Rh positive. Continue fetal monitoring for a minimum of ---- hours for any viable pregnancy and up to _____ hours if there is abdominal trauma - CORRECT ANSWER -6..... 24 Sonography has __________ for diagnosis placental abruption, - CORRECT ANSWER -
POOR.... they miss 50 -80% of abruptions. In addition to routine labs a - CORRECT ANSWER -Prothrombin (PT ) and PTT and serial coags should be drawn. Beta Human Chorionic gonadotropin (BHCG) Measure and record fundal height every - CORRECT ANSWER -30 minutes. Pediatric Mechanisms of injury and biomechanics - CORRECT ANSWER -Blunt trauma MVC > suffocations > drownings > fires/burns. No. 1 cause of fatalities is TBI. Primary Survey/ Resuscitation - CORRECT ANSWER -Survival rates in pediatric emergency can be directly correlated with 1.RAPID AIRWAY MANAGEMENT, 2.INITIATION OF VENTILATORY SUPPORT, AND 3.EARLY RECOGNITION OF AND EARLY RESPONSE TO INTRA abdominal AND intracranial hemorrhages
