Answer to Question 1

ANS: B, C, E
Infant behavior is divided into sleep and awake states. REM sleep is accompanied by irregular respirations, visible REM activity under closed eyelids, and irregular sucking motions. Jerking movements may occur during crying as the infant discharges energy. When offending stimulation is removed, infants tend to fall back to sleep. Quiet motor activity occurs during the wide-awake state. Stimulation increases motor activity in the active alert state.

Answer to Question 2

ANS: B, C, E
Hypoxia causes blood oxygen levels (PO2) and pH to drop. Subsequently, blood carbon dioxide levels (PCO2) begin to rise and prompt the respiratory center within the medulla to initiate breathing. Once the fetus moves from the intrauterine to the extrauterine environment, the drastic change in temperature helps to stimulate the initiation of respirations, because sensors in the skin respond to the temperature changes and send signals to the respiratory system in the brain. Recoil of the chest wall after delivery of the neonate's trunk creates a negative intrathoracic pressure, which facilitates a small, passive inspiration of air. An extremely sensory-overloaded environment filled with a multitude of tactile, visual, and auditory stimuli aids in the initiation of respirations.
A quiet environment and breastfeeding do not assist in the initiation of independent respiratory function.
