CCRN Neonatal Exam Questions and Answers 2024

A deformation is a(n) - abnormality caused by unusual mechanical forces on normal tissue. A low birth weight infant's temperature increases during skin-to-skin care. This is an example of heat transfer by - conduction. At the onset of labor the release of catecholamines stimulates - increased absorption of lung fluid. An edematous, bruised lesion on the right anterior scalp where the vacuum was applied. This lesion has clearly demarcated edges, is firm to touch, and does not cross the suture line. This is best described as a - cephalohematoma. An infant born at 40 5/7 weeks gestation and weighed 5 lbs 2oz (2,360 grams). In completing a gestational age assessment on this infant, you would identify her as - term, small for gestational age. During fetal life, the ductus arteriosus - diverts blood flow from the pulmonary artery to the descending aorta. Expected findings in a neonate born to a mother who received magnesium sulfate in labor include - hypotonia. Eye prophylaxis with a single-use dose of sterile ophthalmic ointment containing 1% tetracycline or 0.5% erythromycin is usually administered within the first few hours of birth to prevent an eye infection caused by - gonorrhea. Following a birth complicated by shoulder dystocia, the neonate should be assessed for - Erb's palsy. Preeclampsia may result in all of the following fetal conditions - growth restriction, hypoxia/neurological injury, prematurity. Hyperthermia is defined as an axillary temperature greater than 99.5ºF (37.5ºC). The MOST common cause of hyperthermia in the newborn is - environmental. In the immediate newborn transition period, the ability to maintain functional residual lung capacity is most dependent upon - an adequate amount of alveolar surfactant. Neonates at risk of hypoglycemia should have their glucose levels evaluated within 2 hours of life because - blood glucose levels reach their lowest point within one to two hours after delivery. Polycythemia in the immediate newborn period is often associated with - infant of a diabetic mother. Symptoms of mild perinatal asphyxia include - 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 - harlequin phenomena. The following conditions may all lead to metabolic acidosis - 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 - 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 - 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 - 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 - pulmonary hypertension of the newborn. The development of pneumonia in chronically ventilated infants is most commonly associated with which of the following organisms? - Ureaplasma urealyticum Antenatal steroids enhance lung maturation by - increasing the number of type II pneumocytes in the lung. Mean airway pressure is defined as the - 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. - Nitric oxide
