1. cut: When the cord is ________, air inflates lungs with first breath
2. 1. Mechanical factors
2. Chemical stimuli
3. Thermal Stimuli
4. Sensory stimuli: What are the four factors that are thought to stimulate the newborn to take its first breath
3. Removal of fluid from the lungs and replacements of air is the primary
mechanical factor. The fetal chest compression that occurs during a vaginal
birth increases the intrathoracic pressure and helps push fluid out of the
lungs: Mechanical factors:
4. hypercarbia, acidosis, and hypoxia which stimulate the respiratory center in
the brain to initiate breathing: Chemical stimuli:
5. decrease in environment temperature leads to skin stimulation which leads
to rhythmic breathing: Thermal Stimuli:
6. Sensory stimuli: Tactile (thorough drying), auditory & visual
7. -Closure of ducts venous and formen ovale
-Closure of the ductus arterious which increases blood flow in pulmonary
vascular sys
-Increase in aortic pressure decrease in venous pressure from the loss of the
placenta
-Increase in systemic pressure decrease pulmonary artery pressure from de-
creased pulmonary circulatory resistance & vasodilation: State four anatomic and physi-
ologic changes that occur in the cardiovascular system during the transition from fetal to neonatal circulation.
8. conduction: Loss of body heat from direct contact with a cooler surface
9. convection: flow of heat from the body surface to cooler environmental air (fan blowing air)
10. evaporation: loss of heat as surface liquid is converted to vapor (rub newborn dry
11. radiation: loss of heat from body to color surface that is close but not touching (keep newborn away from cold
window)
12. should be lying curled up with arms and legs in moderate flexion
because they are full term, they have adequate muscle development: What position
do most newborns usually assume? Why?
13. Physiologic jaundice appears on day 2-3 after delivery due to the breakdown
of RBCs and the liver's decreased ability to excrete billirubin in the blood and

fatty tissue under the skin. It is usually gone by the 10th or 14th day.: Describe
physiologic jaundice. Include why the time of onset of the jaundice is important.
14. : Review the Ballard's gestational age assessment chart in text page 796.
15. 36.5 degrees C to 37.5 degrees C (average= 37 degrees C): newborn initial assessment:
normal temperature
16. 110 to 160 bpm: newborn initial assessment: normal pulse
17. 30-60 breaths/min with periods of apnea (less than 15 seconds): newborn initial
assessment: normal respirations
18. systolic- 60 to 80 diastolic- 40 to 50: newborn initial assessment: normal BP
19. 5.5 to 8.8 lbs (2,500 g to 4,000 g): newborn initial assessment: normal weight
20. 45 to 55 cm (18 to 22 in.): newborn initial assessment: normal height
21. 32 to 36.8 cm (12.6 to 14.5 in): newborn initial assessment: normal circumference of head
22. 30 to 33 cm (12-13 in.): newborn initial assessment: normal circumference of chest
23. 5-10%: Usual weight loss within the first 3 to 4 days of life for a full-term newborn is __________%
24. Small fluid intake, meconium stools, and increased urination: Why does the new-
born commonly exhibit a "physiologic weight loss"?
25. reddened skin color over half of the infant's body: harlequin color change
26. Pink rash that appears suddenly anywhere on the body of a term newborn
during the first 3 weeks; no treatment required: erythema neonatorum toxicum
27. Flat pink or red marks that easily blanch and are found on the neck, nose,
eyelids, and forehead; fade by age 2: telangiectatic nevi (stork bites)
28. capillary angioma below the surface of the skin that purple or red; varies
in size and shape; commonly seen on forehead; not blanchable: nevus flammeus
(port-wine stain)
29. Blue/purple spots of pigmentation noted on back, shoulders, and butt; com-
mon on infants with darker skin: Mongolian spots
30. red-purple overgrowth of capillary blood vessels: Nevus vasculosus (strawberry mark)
31. Subperiosteal hemorrhage resulting from a traumatic birth: Which statement best
defines a cephalhematorma?
a) diffuse edema of the scalp resulting from compression of local blood vessels.
b) Subperiosteal hemorrhage resulting from a traumatic birth
c) Temporary reshaping of the skull resulting from the pressure of birth
