capacity is most dependent upon - CORRECT ANSWER an adequate amount of
alveolar surfactant.
Neonates at risk of hypoglycemia should have their glucose levels evaluated within 2 hours
of life because - CORRECT ANSWER blood glucose levels reach their lowest point
within one to two hours after delivery.
Polycythemia in the immediate newborn period is often associated with - CORRECT
ANSWER infant of a diabetic mother.
Symptoms of mild perinatal asphyxia include - CORRECT ANSWER hyperalert state
and jitteriness.
The condition in which the newborn's immature hypothalamus does not regulate peripheral
blood vessels, resulting in a vasoconstriction on one side of the body with a vasodilation on
the opposite side of the body is called - CORRECT ANSWER harlequin phenomena.
The following conditions may all lead to metabolic acidosis - CORRECT
ANSWER loss of HCO3/excess acid load d/t prematurity, renal tubular necrosis, severe
diarrhea, hypoxia, hypoperfusion, inborn errors of metabolism, caloric deprivation,
intolerance of cow's milk protein.
,The full newborn cardiovascular assessment includes auscultation, inspection, and palpation.
The point of maximum impulse is usually palpable and can be auscultated in the - CORRECT
ANSWER third to fourth intercostal space and left of the midclavicular line.
The neonate born to a mother with uncontrolled diabetes mellitus should be evaluated for -
CORRECT ANSWER congenital malformations.
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 -
CORRECT ANSWER increased oxygen consumption and hypoxia.
A full term neonate who presents at six hours of age with increasingly labile oxygenation that
appears disproportionate to the pulmonary disease should be evaluated for - CORRECT
ANSWER pulmonary hypertension of the newborn.
The development of pneumonia in chronically ventilated infants is most commonly
associated with which of the following organisms? - CORRECT
ANSWER Ureaplasma urealyticum
Antenatal steroids enhance lung maturation by - CORRECT ANSWER increasing the
number of type II pneumocytes in the lung.
Mean airway pressure is defined as the - CORRECT 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. - CORRECT ANSWER Nitric oxide
The following arterial blood gas results: pH 7.28, PaO2 74, PaCO2 55, HCO3- 21 and base
deficit -4 indicate - CORRECT 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 recovered by five minutes of
life. On admission to the NICU, her temperature was 36° C. After admission to the NICU, her
arterial blood gas is pH: 7.19, PCO2: 63, HCO3: 14. The correct interpretation of this blood
gas is - CORRECT ANSWER mixed respiratory and metabolic acidosis.
Which statement is most accurate when identifying the pathophysiology of transient
tachypnea of the newborn (TTN)? - CORRECT ANSWER Labor enhances the process
of fetal lung fluid absorption
During which phase of fetal pulmonary development do the type II pneumocytes become
numerous and begin to produce and store surfactant? - CORRECT
ANSWER Canalicular phase
An absence of air flow despite respiratory effort is an example of which apnea classification?
- CORRECT ANSWER Obstructive apnea
Continuous positive airway pressure (CPAP) improves oxygenation by - CORRECT
ANSWER improving the ventilation-perfusion ratio.
The functional residual capacity in a newborn infant should be approximately - CORRECT
ANSWER 30 ml/kg.
A 29 week gestation infant who displays symptoms of a pulmonary hemorrhage should be
evaluated for - CORRECT ANSWER patent ductus arteriosus.
The most significant role of surfactant in neonatal lung development is to - CORRECT
ANSWER maintain alveolar stability by decreasing surface tension.
Most respiratory disorders result in a ventilation-perfusion mismatch. Ideally, the ventilation-
perfusion ratio should be - CORRECT ANSWER 1 to 1
