NU201 Dawn Exam 3 Questions And Answers
Cardiovascular system at birth
-change with infants first breath (in utero blood oxygenated via placenta; now via lungs)
-as lung inflate for first time, pressure in pulmonary artery is decreased
-increased O2 pressure causes ductus arteriosus to contract and close after few days
-increased pulmonary blood flow increases pressure in left atrium
-umbilical arteries and vein, ductus arteriosus and ductus venosus no longer receive
blood
-most heart murmurs go away by 6 months
-blood volume 100ml/kg first few days (doubles by 1 year)
-peripheral circulation sluggish first day (hands and feet cool or cyanotic)
-BP 80/42
Blood values
-Hgb 17-19
-Hct 57-58
-Hgb down to 12 by 3 months

Decreased vitamin K levels
-intestine sterile at birth
-need intestinal flora to form vitamin K
Heart rate
-110-160 (down to 100 if sleeping; up to 180 if crying)
-irregular often related to immaturity of cardiac regulatory center in medulla
-heart sounds high pitched
respirations after c section
-c section baby doesn't have fluid squeezed out, so harder for them to establish
respirations
-some lung fluid is squeezed out during vaginal delivery
-remaining lung fluid absorbed into lymph and blood

Resp rate
-30-60 at rest (increased when crying)
-often irregular with short periods of apnea, with no cyanosis
-rate stabilizes by 24 hrs old
-chest and abdomen rise and fall together with inspirations (see saw resps are not
normal)
Should void within 24 hours after birth

First voiding may be pink (uric acid crystals that were formed in bladder in utero)
First voiding may be pink uric acid crystals that were formed in bladder in utero
Neurological function
Check muscle tone and reflexes
Infant should be able to move both arms and legs and attempt head control
Immunity
-newborn has hypofunction of inflammatory and immune responses at risk for infection
first few months
-difficulty forming antibodies until 2 months old
