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

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

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.
