newborn transition
| Question | Answer |
|---|---|
| lungs | site of gas exchange |
| heart circulation | pressure increase in left atrium causing foreman ovale to close |
| hepatic portal | ductus venosus closes, hepatic portal circulation begins |
| thermoregulation | body temperature is maintained through flexed posture and brown fat |
| 120-180 beats per minute | heart rate first few minutes of birth; decreases to average 120 bpm |
| cord blood | natures first stem cell trasnfplant because it possess regenerative properties |
| surfactant | surface tension reducing lipoprotein -prevents alveolar collapse |
| periodic breathing | cessation of breathing that lasts 5-10 seconds without changes in color or heart rate |
| thin skin with blood vessels close to the surface, lack of shivering ability limited stores of glucose, lack of subcutaneous fat | heat loss |
| newborn temperature | may decrease 3-5 degrees within minutes 99.6 |
| conduction | trasnsfer of heat from one object to another when the 2 objects are in direct contact with each other-heat fluctuations from the newborn surgace to other surfaces such as cold mattress, scale |
| convection | flow of heat from the body surface to cooler surrounding air or to air circulating over a body surface. cool breeze from an open door |
| evaporation | loss of heat when a liquid is converted to a vapor.amniotic fluid evaporating into the air causing this type of heat loss - apply hats and blankets |
| radiation | loss of body heat to cooler, solid surfaces that are in proximity but not in direct contact - placing the newbown in a isolette next to a cold window |
| overheating | isolette that is too warm or one that is left too close to a sunny window can cause this |
| non shivering thermogenesis | primary method of heat production-which brown fat (adipose tissue) is oxidized is response to cold exposure |
| jaundice | icterus-yellowing of skin , sclera, and mucous membranes due to increase bilirubin |
| meconium | newborns first stool; amniotic cluid, shed mucosal cells and intestinal secretions and blood |
| feeding | small frequent feedings |
| breast fed stool | yellow gold loose and stringy - |
| formula fed | yellow, yellow green or greenish and loose pasty or formed with an unpleasant odor |
| acquired immunity | 2 primary processes - development of circulating antibodies and formation of activated lymphocytes used to destroy foreign invaders |
| IgA | found in breast milk, causing a significant immunologic advantage |
| hearing | reponds to noice by turning to sound |
| taste | ability to distinguish between sweet and sour by 72 hours old |
| smell | knows difference between moms breast milk and others |
| touch | sensitive to pain, tactile stimuli |
| vision | incomplete at birth; close objects 8-10 inches |
| reflex | involuntary muscular reponse to a sensory stimulus |
| first period of rectivity | birth and may last from 30 min to 2 hours-alert, moving and may appear hungry- good to intiate breast feeding now |
| decreased reponsiveness | 30-120 minutes of age -good for mom and newborn to stay close and rest |
| second period of reactivity | 2-8 hours - newborn passes meconium-teaching about feeding and diaper changing techinique is reinforced now |
| neurobehavioral response | how they react to the environement - orientation, habituation, motor maturity, social behaviors and self-quieting ability |
| orientation | response to stimuli |
| habituation | process and respons to visual and auditory stimuli |
| motor maturity | control and coordinate movement |
| self-quieting ability | ability to quiet and comfort themselves |
| social behaviors | cuddling/snuggling into the arms of the parent when held- |
| neonatal period | first 28 days of life |
