Air Methods Critical Care exam Questions With All
Correct Answers
What is the most reliable method of confirming and montioring correct
placement of an ET tube? correct answer -Continuous waveform
capnography
The upper airway consists of... correct answer -Nose, Mouth, Jaw, Oral
Cavity, Pharynx, and Larynx
No gas exchange occurs here __________, it's called ____________. correct answer
-Nose to terminal bronchioles, anatomical dead space. (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 type of blood should a pregnant trauma patient receive? correct
answer -O-NEG baybay.
Initiate cardiotocography in any mother correct answer -20 or more
weeks gestation, must be monitored for at least 6 hours.
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.
