Document Summary
The basis of five signs indicating his or her physiological state. Lecture 5: physiological adaptations of the newborn and nursing care of the newborn & family. 2 points maximum for each of the following: If less than 7; reevaluated at 10 and 20 minutes. Second period of reactivity: 2-8 hours after birth, can last from 10 min to several hours, hr, rr, muscle tone, gi activity all increase. The first breath is triggered by light, cold, noise, decreased po2, increased pco2. Large pressure is required to open alveoli and move the lung fluid. Surfactant is required to decrease surface tension and maintain alveolar stability. Adaptation begins with cord clamping and the first breath. The following anatomical structures close: ductus arteriosus, ductus venosus, foramen ovale. **picture of anatomy structures (resource for circulatory system after birth: https://www. youtube. com/watch?time_continue=10&v=jfn0dyu5wuw ) Prevention of ophthalmia neonatorum: inflammation of the eyes from gonorrheal or chlamydial infection, contracted by the newborn during the passage through the mother"s.
