A newborn exhibits signs of respiratory distress due to the lack of surfactant. She has signs of low oxygen and high carbon dioxide.Explain why the lack of surfactant would result in respiratory distress. Furthermore, what type of acid-base disorder might she develop and how would her body compensate. Explain the Physiology and Correlation. Add references.

Case Study 3 Kirsten, a 3-month-old infant, has begun to have frequent loose stools that progress to a watery diarrhea. She is unresponsive, with dry mucous membranes; sunken fontanelles; and little, if any, urine output. Respirations are rapid and the heart rate is elevated. Discussion Questions 1. What acid-base imbalance is Kirsten experiencing, and how is this affecting her ability to compensate? 2. What is the cause of oliguria, and how does this complicate the situation? 3. How will hydration affect Kirsten's ability to compensate for the acid-base imbalance?

Cathy has just given birth to a little girl. When the nurse tried to feed her or bathe her, the baby becomes cyanotic. Physical examination indicates no structural deformities. Blood gas levels show only 60% saturation with oxygen. What may be causing this problem? a. the infant has a malformed digestive system b. the lungs are hyperventilating c. the lungs are hypoventilating d. the cardiovascular supply of the lungs is impaired e. the infant is born with only one lung
