Question
nurse assesses neonatal development, identifies common variations in each newborn, and normalities. The nurse can then identify necessary early nursing interventions required for successful Tod ay's neonatal recognizes ab transition to home for the parent-infant unit. his mod ule corresponds to Chapters 27 and 28 in the 10th edition of Olds'Maternal-Newborn Nursing & Women's Health Across the Lifespan. PHYSIOLOGIC ADAPTATIONS When caring for the newborn after a vaginal delivery, the nurse needs to be able to identify the respiratory changes that occur during the transition of the fetus to extrauterine life. Which factor(s) does the nurse recog- nize as contributing to the changes in the newborn's lung function after birth? (Select all that apply.) a. Adequate lung development and production of surfactant 1. b. Marked decrease in pulmonary circulation c. Inspiratory gasp triggered by the elevation in PCO, and decrease in pH and PO, d. Stimulation of skin nerve endings due to chilling e. Chemical stimulator associated with transient asphyxia of the fetus 2. Describe the function of each of the following fetal structures during fetal life and the changes that occur after birth in the newborn Newborn Fetal Tha um Umbilical vein euanrd duwa, too laalAchma dum ( une 1 in bdExplanation / Answer
Answer is option A, E
** Fetal asphyxia abolishes fetal breathing while high fetal PO2values stimulate fetal breathing.
** As the lung matures, more and more of the surfactant are released into fetal lung fluid and subsequently mix with amniotic fluid or are swallowed. By term type II cells in the fetal lung contain much more surfactant than does the adult lung, and this large pool of surfactant is poised for release prior to and at delivery. Thus the term fetus is assured of having adequate surfactant for the transition to air breathing .
