Newborn Nursing The Critical
Components of Nursing Care
3rd Edition!RATED A+
Foramen ovale - ANSWER-opening between the right atrium and the left atrium
- closes when the left atrial pressure is higher than the right atrial pressure
Ductus arteriosus - ANSWER-connects the pulmonary artery with the descending aorta
- usually closes within 15 hours post birth
Brown fat / Non-shivering thermogenesis - ANSWER-Located in the neck, thorax, axilla, scapular areas, around adrenal glands
and kidneys. It increases metabolism, heat production once used it is not replenished. Neonates are at higher risk of
thermoregulatory issues because of higher body surface area to body mass ratio, higher metabolic rates, and immature
thermoregulatory abilities.
The neonatal period - ANSWER-from birth through the first 28 days of life
, Approximately _______ of amniotic fluid is forced out of the lungs in the delivery process. - ANSWER-30mL
Ductus venous - ANSWER-Clamping of the cord causes constriction of the vessels and closure of the ductus venous immediately.
- closes by the 3rd day of life
Evaporation - ANSWER-Loss of heat through conversion of liquid to vapor
Directly after birth or bathing
Convection - ANSWER-Loss of heat from infant's warm body to cooler air currents.
Drafts from windows, AC or oxygen masks
Conduction - ANSWER-Transfer of heat from cooler surface by direct contact.
Cold hands, cold equipment
Signs of Respiratory Distress - ANSWER-Cyanosis
Apnea/tachypnea
Retractions
Grunting
Flaring of nostrils
Hypotonia
Apgar scoring - ANSWER-Taken at 1 and 5 minutes after birth
Neutral thermal environment [NTE] - ANSWER-An environment that maintains body temperature with minimal metabolic
changes and /or oxygen consumption.
Factors that negatively affect thermoregulation - ANSWER-Decreased subcutaneous fat
Decreased brown fat in preterm infants
Large body surface
Loss of heat from convection, radiation, conduction, and/or evaporation
Radiation - ANSWER-Transfer of heat to a colder solid object not in contact with infant.
