Fetal blood is directed from the right atrium across the foramen ovale into
the left atrium, the left ventricle, and the ascending aorta. The ductus
arteriosus is a tubular connection between the pulmonary artery and
descending aorta. The ductus venosus directs blood flow from the
umbilical vein. The umbilical vein carries placental blood to the fetus.
The flow of blood through the foramen ovale results in better oxygenated
fetal blood directed to the myocardium and fetal brain.
A sleeping newborn has a heart rate of 74 beats/min. Which action should
the nurse take?
-Continue with vital sign assessment.
-Auscultate the infant's heart for a murmur.
-Begin resuscitation.
-Pick up the baby and gently rock it. - Answer✔️✔️-Continue with vital sign
assessment.
Since the heart rate may drop to a low of 70 to 90 beats/min in a full-term
newborn during deep sleep, the assessment should continue. Resuscitation
Following birth, a newborn's caloric intake is often insufficient for weight
gain until the newborn is 5 to 10 days old. During this time there may be a
weight loss of 5% to 10% in term newborns, which is caused by a shift of
intracellular water to extracellular space and insensible water loss. The
infant's metabolism is not the cause of the weight loss. Fluid retention
would cause a weight gain.
The nurse is assessing a newborn infant.
Which finding should indicate the newborn is ready to tolerate feedings?
Audible cry while being held
Abdominal distension upon palpation
Active bowel sounds upon auscultation
Ability to suck on a pacifier - Answer✔️✔️-Active bowel sounds upon
auscultation
Active bowel sounds upon auscultation is an indication that the newborn
can tolerate feedings. The ability to suck on a pacifier and an audible cry
may indicate hunger but does not mean that the newborn will tolerate
feedings. Abdominal distention upon palpation may indicate an issue with
digestion.
