PPN 301 Exam Review UPDATED ACTUAL
Exam Questions and CORRECT Answers
physiological adaptations of Newborn - CORRECT ANSWER - - Establishing &
maintaining respirations
- Adjusting to circulatory changes
- Regulating temperature
Est. & Maintain Respirations - CORRECT ANSWER - - ↓Po2 and ↑Pco2, ↓blood pH
- stimulation of respiratory centre (Medulla)
- Crying = distribution of air in lungs
- Skin to skin & sensory to environment
Circulatory changes at birth - CORRECT ANSWER - 1. loss of umbilical arteries, veins,
& ductus venosus
2. ductus arteriosus closes (isolates pulm./syst. circuits)
3. neonate inhales/expands lungs, pulmonary circuit starts
4. blood flows into left atrium = foramen ovale closes
Thermoregulation of newborn - CORRECT ANSWER - - Conduction: blanket under to
reduce heat loss
- Convection: clothes to keep heat
- Evaporation: evaporated water loses heat
- Radiation: Heat lost to colder items/ keep surroundings warm
