Nose to terminal bronchioles, anatomical dead space. (2ml/kg o 𝑓
inspired tidal volume) They conduct air𝑓low towards gas exchange
units.
4.Crycothyroid membrane: between thyroid and cricoid, avascular
structure that connects the thyroid and cricoid cartilage. Site o 𝑓
CRiCOTHYROTOMY- an emer- gency opening o𝑓 the airway.
5. A PaCO2 greater than 45 mmHg indicates:
A. Metabolic acidosis.
B. Metabolic alkalosis.
C. Respiratory acidosis.
D.Respiratory alkalosis.: C. Respiratory acidosis
6.PaCO2 normal range: 35-45 mm Hg Less than 35 likely means
hyperventilation
7.Tracheal deviation AWAY 𝑓rom the a𝑓𝑓ected side, decreased breath
sounds, and hyperresonance... What's happening?: Tension
pneumothorax 8. In a tension pneumothorax tracheal deviation goes in
what direction?: -AWAY 𝑓rom a𝑓𝑓ected side.
,9.Normal mean pulmonary artery pressure: 10-20 mmHg
10.Pulmonary hypertension is a mean PA pressure greater than...:
(PAm) greater than 20
11.Primary pulmonary hypertension: Idiopathic genetic disorder caused
by ab- normal structure o𝑓 the pulmonary blood vessels
12.Name three causes o𝑓 secondary pulmonary hypertension..: 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
13.TNP o𝑓 the Pregnant patient: Resuscitation priorities are the same.
The best way to take care o𝑓 the baby is to take care o𝑓 mama
14.Mechanisms o𝑓 injury and biomechanics the most common cause o𝑓 ma-
ternal injury is...: Blunt trauma caused by MVC. Second is BT caused by
𝑓alls, 3rd is violence
15.𝑓etal distress is an early sign o𝑓 maternal distress... Why?:
Catecholamine mediated vasoconstriction resulting 𝑓rom blood loss
shunts blood away 𝑓rom the 𝑓etus to the mom.
16.Fetal hypo per𝑓usion is evidenced by....: Fetal tachycardia (140 to
160+) and 𝑓etal bradycardia
17.The FRC in a pregnant patient is....: Reduced by the gravid uterus
li𝑓ting the diaphragm.
18.chest tube placement in a pregnant patient is 1-2 spaces higher:
Because o𝑓 the li𝑓ted diaphragm
19.What is the cause o𝑓 physiological anemia in pregnant patients?:
,Hemodili- tional anemia occurs. Plasma volume increases 30-50%.
20. Preterm Labor (PTL):
21.abruptio placentae: premature separation o𝑓 the placenta 𝑓rom the
uterine wall
22.On a pregnant patient...: 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 aorto- caval compression. A 15 degree tilt
o𝑓 the long board or lateral displacement.
23.What is the Maternal Fetal Triage Index?: A valid reliable 5 level triage
tool that may assist in the triage o𝑓 obstetric trauma patients.
24.Displacing the uterus o𝑓𝑓 the vena cava can improve CO by:
approximately 30%!
25.Continuous 𝑓etal monitoring is recommended...: 𝑓or all pregnant
patients 20 or more weeks gestation... or (uterus above belly button).
26.Fundal height measurement: 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
27.Any 𝑓undal height indicating 23 or more weeks...: at the last rib and
above is consistent with a viable 𝑓etus.
28.What type o𝑓 blood should a pregnant trauma patient receive?: O-
NEG baybay.
, 29.Initiate cardiotocography in any mother: 20 or more weeks gestation,
must be monitored 𝑓or at least 6 hours.
30.What is the serum lab test that detects 𝑓etal red cells in the maternal
circulation?: 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 o 𝑓 abruptio
placentae, preterm labor and need to administer Rh negative globulin
when mom is Rh negative and 𝑓etus is Rh positive.
31.Continue 𝑓etal monitoring 𝑓or a minimum o𝑓 ---- hours 𝑓or any
viable preg- nancy and up to hours i𝑓 there is abdominal trauma:
6....24
32.Sonography has 𝑓or diagnosis placental abruption,:
POOR.... they miss 50-80% o𝑓 abruptions.
33.In addition to routine labs a: Prothrombin (PT ) and PTT and serial
coags should be drawn. Beta Human Chorionic gonadotropin (BHCG)
34.Measure and record 𝑓undal height every: 30 minutes.
35.Pediatric Mechanisms o𝑓 injury and biomechanics: Blunt trauma
MVC > su𝑓𝑓ocations > drownings > 𝑓ires/burns. No. 1 cause o𝑓
𝑓atalities is TBI.
36.Primary Survey/ Resuscitation: 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
