Ch 3 and 4 Flashcards
Fetal Monitoring
Measuring heart rate of baby
-Used 80% of pregnancies
Analgesics
Limit pain to pelvic region
-Epidurals
Risks of medication during birth
Nursing, alertness, irritability, c-section
Small-for-Date
Born at due date or preterm but below expected weight for length of pregnancy
Newborn Reflexes
Eye blink, Rooting, Moro, Babinski, Palmar Grasp, Sucking
-Many become voluntary over time
Rooting
Touch cheek and turn head
-Newborn reflex
Palmar Grasp
Press palm and hand grasps
-Newborn reflex
Moro
Arch back and reach out and hug self
-Newborn reflex
Babinski
Toes span when rub bottom of foot
-Newborn reflex
Newborn Sense of Touch
Sensitive to touch on mouth, palms, soles of feet
- Highly sensitive to pain
- Mother or breast milk, sugar solution, gentle holding help ease pain
Newborn Taste
Prefer sweet tastes
-Quickly learn to like new tastes with exposure
Newborn Smell
Can locate odors and identify mother by smell from birth
Newborn Hearing
Can hear a wide variety of sounds at birth
- Prefer complex sounds to pure tones
- Sensitive to voices, maybe prepared to learn languages
Newborn Vision
Least developed sense at birth
- Limited acuity and eye/brain structures not strengthened
- Color vision improves in first 2 months (adultlike in 4)
Hormones in parents
Oxytocin
- Prolactins and estrogens increase and androgens (in males) decrease
- Improves reaction to child and caregiving
- Dependent upon interaction w/ baby
Body Size year 1 and 2
Rapid growth
- Infants typically double birth weight by 5th month and triple by first bday
- Body proportions become more adultlike
- Weight increase is in fat
Head-Sparing
When nutrition is temporarily inadequate, body stops growing but not the brain
Skeletal Age
Best indicator of physical maturation
-Measure of development of mature bone (ossification)
Growth differences
Males ahead in body size
- Females ahead in skeletal age
- African Americans ahead in both
Cephalocaudal
Head grows faster than legs
-Legs catch up by age 2
Proximodistal
Head, chest, and trunk grow faster than hands and feet
Synaptic Pruning
- During first 2 years
- Directed by genetic programming and environmental stimulation
- Develop neural networks to serve certain functions
Specialized areas of cerebral cortex
- Visual cortex-vision
- Auditory cortex-hearing
- Prefrontal cortex-planning and self-regulation
Left Hemisphere
Sensory info and control of R body
- Regulating and processing (+) emotion
- Verbal abilities
- Sequential, analytic processing
