CH. 42 NEONATAL CARE Flashcards
a decrease in the amount of oxygen delivered to the extremities. The hands and feet turn blue because of narrowing of the arteries toward the arms and legs
acrocyanosis
a clear slightly yellowish liquid that surrounds the fetus during pregnancy and contained in the amniotic sac
amniotic fluid
scale used to assess the status of a newborn 1 and 5 minutes after birth
Apgar score
respiratory pause greater than or equal to 20 seconds
apnea
condition of severely deficient supply of oxygen to the body leading to end organ damage
asphyxia
a hole in the atrial septal wall that allows oxygenated and deoxygenated blood to mix; patients with this hole have a higher incidence of stroke
atrial septal defect (ASD)
a pulse rate of less than 100 beats/min in the newborn
bradycardia
bluish coloration of the skin due to the presence of deoxygenated hemoglobin in blood vessels near the skin
central cyanosis
a narrowing or blockage of the nasal airway by membranous or bony tissue; a congenital condition meaning it is present at birth
choanal atresia
an abnormal defect or fissure in the upper lip that failed to close during development and is often associated with cleft palate
cleft lip
a fissure or hole in the palate (roof of the mouth) that forms a communicating pathway between the mouth and nasal cavities
cleft palate
pinching or narrowing of the aorta that obstructs blood flow from the heart to the systemic circulation
coarctation of the aorta (CoA)
the most common birth defect and associated with hypoxia in the newborn period requiring intervention during the first months of life
congenital heart disease (CHD)
passage of loops of bowel with or without other abdominal organs through a developmental defect in the diaphragm muscle; occurs as the bowel from the abdomen herniates upward through the diaphragm into the chest cavity
diaphragmatic hernia
lack of movement at the shoulder due to nerve injury resulting from the stretching of the cervical nerve roots (C5 and C6) during the delivery of the newborns head during birth. The effect is usually transient but can be permanent
Erb Palsy
the process through which the fluid in the fetal lungs is replaced with air, the ductus arteriosus constricts and the newborn begins adequate oxygenation of its own blood
fetal transition
an opening in the septum of the heart that closes after birth
foramen ovale
oxygen administered via an oxygen tube and a cupped hand on patient’s face
free flow oxygen
seizure activity that is bilateral synchronous and nonmigratory
generalized seizure
period of time from conception to birth
gestation
noises heard when an infant is having difficulty breathing; short inarticulate guttural sounds as effort is expended
grunting
a deficiency of glucose in the blood caused by too much insulin or too little glucose; in the newborn it is a level of less than 40 mg/dL, and in older neonates it is a level of less than 60 mg/dL
hypoglycemia
underdevelopment of the aorta, aortic valve, left ventricle, and mitral valve; this defect involves the entire left side of the heart
hypoplastic left heart syndrome (HLHS)
a condition in which the core body temperature is significantly below normal (less than 35 degrees celsius)
hypothermia
low or poor muscle tone (floppy)
hypotonia
damage to cells in the central nervous system like the brain and spinal cord from inadequate oxygen
hypoxia ischemic encephalopathy
marked hypertrophy and hyperplasia of the two (circular and longitudinal) muscular layers of the pylorus resulting in the pylorus becoming thick and obstructing the end of the stomach
intercostal retractions
