You are the nurse caring for a 38 weeks gestation, female infant, who was born one
hour ago in the parking lot of the emergency room. On admission to the nursery, the
neonate's rectal temperature was 95ºF (35ºC). You recognize that cold stress may
predispose the infant to - ANSWER-increased oxygen consumption and hypoxia.

oxygenation that appears disproportionate to the pulmonary disease should be
evaluated for - ANSWER-pulmonary hypertension of the newborn.
The development of pneumonia in chronically ventilated infants is most commonly
associated with which of the following organisms? - ANSWER-Ureaplasma
urealyticum
Antenatal steroids enhance lung maturation by - ANSWER-increasing the number of
type II pneumocytes in the lung.
Mean airway pressure is defined as the - ANSWER-pressure transmitted to the lung
throughout the respiratory cycle.
, Many infants with the diagnosis of persistent pulmonary hypertension (PPHN) will
have pharmacologic support. Identify the medication that is a direct-acting
vasodilator and acts by relaxing pulmonary vessel musculature. - ANSWER-Nitric
oxide
The following arterial blood gas results: pH 7.28, PaO2 74, PaCO2 55, HCO3- 21 and
base deficit -4 indicate - ANSWER-respiratory acidosis.
Nastassia is a one-hour-old neonate, born at 39 weeks gestation by primary cesarean
birth for fetal bradycardia. She was hypotonic at birth with gasping respirations and
a heart rate of 80. She was provided bulb suctioning and bag mask ventilation and
