NURS 316 Exam 2Questions and
answers
Nursing interventions for newborn thermoregulation - ✅✅Dry newborn
Skin to skin swaddled in warm blankets
Convection - ✅✅Heat loss by air or water moving across the skin surface
Evaporation - ✅✅Body heat turns sweat into vapor. Active work contributes to
heat loss
Radiation - ✅✅Bare skin is exposed to an environment containing objects of
cooler temperature
Conduction - ✅✅Direct contact with an object
First breath for newborns - ✅✅Lungs transition from fluid filled to air filled
after birth
First breath inflates lungs, increasing pulmonary blood flow
Surfactant in fetal lungs purpose - ✅✅Helps alveoli expand
Prevents alveolar collapse, ensuring effective gas exchange
Expected newborn respiratory rate - ✅✅30-60 breaths/min
,Cardiovascular changes in newborn - ✅✅Changes when cord is clamped and
1st breath
Decrease in pulmonary vascular resistance
Closing of 3 shunts
Ductus arteriosus - ✅✅Bypasses fetal lungs
Foramen ovale - ✅✅Allows blood to cross atria, bypassing lungs
Ductus venosus - ✅✅Directs blood from umbilical vein to inferior vena cava,
bypassing liver
Normal heart rate for newborn - ✅✅110-160 beats/min
Where is blood produced in utero? - ✅✅Liver
HbF, fetal hemoglobin - ✅✅Lower arterial oxygen pressures in newborns
compared to adults
Renal production in utero/newborn - ✅✅In utero, managed by placenta
Urine production at 16 weeks gestation
, Urine, renal blood flow and GFR increase at birth
Acrocyanosis - ✅✅Normal bluish discoloration of hands and feet
Lanugo - ✅✅Fine, soft hair presents on various body parts
Typically sheds within first few weeks
Vernix - ✅✅Protective waxy coating, shield from amniotic fluid, delayed
bathing
Fontanels - ✅✅Gaps between a baby's skull: anterior and posterior fontanels
Allows for brain expansion and facilitate birth process
Newborn has approximately ___ bones - ✅✅270
Sleep-wake cycle for newborns - ✅✅16-18 hrs per day of sleep
2.5-4 hrs awake at a time
When do sleep changes occur in newborns? - ✅✅2-3 months
