A pregnant woman at 25 weeks gestation visits the prenatal clinic for a check-up. She asks the nurse how the baby is able to breathe on his own following childbirth.
The nurse explains the factors that influence the initiation of the newborn's first breath including:
A) Hypoxia causes blood oxygen levels (pOB) and pH to rise and blood carbon dioxide levels (pCOB) begin to fall and prompt the respiratory center within the medulla to initiate breathing.
B) The drastic change in temperature helps to stimulate the initiation of respirations since sensors in the skin respond to the temperature changes and send signals to the respiratory system in the brain.
C) Recoil of the chest wall after delivery of the neonate's trunk creates a positive intrathoracic pressure, which facilitates a small, passive inspiration of air.
D) A quiet environment with reduced tactile, visual and auditory stimuli aids in the initiation of respirations.
Question 2
The nurse would prepare a client for amnioinfusion when which of the following occurs?
A) Severe variable decelerations are due to cord compression.
B) The fetal presenting part fails to rotate fully and descend in the pelvis.
C) The fetus shows nonreassuring fetal heart rate patterns.
D) Maternal pushing is compromised by anesthesia.
