Maternal Infant - Exam 2: Newborn Adaptation And Care 2025
What is a preterm infant? - Answer--an infant born after 20 weeks but before 37 weeks
How many weeks is a full term infant? - Answer--37-41 weeks
How many weeks is a post term infant? - Answer--greater than 42 weeks
What is the popliteal angle of a premature infant? - Answer--their leg would extend to the forehead
What is the popliteal angle of a term infant? - Answer--90 degrees of flexion
What is conduction heat loss? - Answer--heat loss due to transfer of warmth from the infant to a cold
surface
What is convection heat loss? - Answer--loss of heat from the infant's body to circulating air
How can infant heat loss be prevented? - Answer--- always keep infants bundled in clothing to minimize
the exposed surface are
- dry infants thoroughly after birth and baths
What is brown fat and what is it used for? - Answer--large fat cells which are easily broken down to
generate heat energy
, - once it is used, it is gone forever
True or false: premature infants have the ability to shiver - Answer--False, only term infants can do this
but it is a sign of late hypothermia
Why is shivering and fat metabolism bad for infants? - Answer--it increases their O2 and calorie
consumption which are not abundant in newborns
How does aortic pressure change after birth? - Answer--aortic pressure increases after the umbilical
cord is clamped
How does venous pressure change after birth? - Answer--venous pressure decreases after the umbilical
cord is clamped
How does pulmonary artery pressure change after birth? - Answer--pulmonary artery pressure
decreases to allow blood to be oxygenated by the lungs
- change takes place after the first breath
What is the ductus venosus and how does it change after birth? - Answer--it is a vascular structure which
connects the umbilical vein to the inferior vena cava to provide O2
- clots over the first few days of life
What is the foramen ovale and how does it change after birth? - Answer--a pathway in the heart which
connects the right and left atria
- closes within the first few minutes as right atrial pressure decreases
What is the ductus arteriosus and how does it change after birth? - Answer--a small blood vessel which
connect the pulmonary artery to the aorta
- constricts as O2 increases in the first hours of life
