NM705 MODULE 1 EXAM REVIEW (SESSION 1)
QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS
4 mechanisms through which newborns lose heat
convection, conduction, radiation, evaporation
Convection
loss of heat through body surface to cooler air currents (air conditioner, fan, O2 mask)
Conduction
heat transfer from NB to cooler surface via direct contact
Evaporation
heat loss from energy exchange due to evaporation of liquid (can also cause
dehydration)
radiation
transfer of heat to or from nb to object not in direct contact (heat lamp, walls, windows)
pathway of fetal circulation from the placenta to the left atrium
Umbilical Vein, Ductus Venosus, Inferior Vena Cava, Right Atrium, Foramen Ovale, Left
Atrium
tachypnea, poor feeding, and temperature instability are symptoms of...
hypoglycemia
the newborn can create heat in these three ways
, non-shivering thermogenesis, voluntary movement, shivering
bronchioles, alveolar ducts and the beginnings of terminal sac are hallmarks of
development in this gestation or stage
mid-canalicular
this is characterized by high pulmonary resistance and low systemic vascular
resistance
fetal circulation
hematocrit normal range
43-63%
delayed passage of this may result in higher bilirubin levels in the newborn
meconium
production of surfactant begins at this gestation or stage
20-24 weeks
this is the normal newborn temperature range (in C)
36.5-37.4 C or 97.5-99.3 F
Normal NB RR
40 - 60, diaphragmatic and abd breathing
<30 not ok
REFER for >60 w/ or w/o other distress
the midwife would encourage breastfeeding with this glucose finding
always (but especially under 40)
at birth lung fluid drains by these mechanisms
lymphatics, nose/mouth (thoracic squeeze), pulmonary vasculature
