Pediatrics Flashcards
(301 cards)
the most common condition found in premature newborns; it can lead to heart failure and inadequate oxygenation of the brain
patent ductus ateriosus
opening in the septum between the right and left atrium; results in ‘wet lungs’ (blood) and may lead to respiratory infection; right ventricle works hard and may lead to heart failure; poor exercise tolerance and small for chronological age
atrial septal deficits
one or more openings in the muscular or membranous portions of the ventricular septum; 50% self-correct by age 5; may result in Eisenmenger’s complex, pulmonary vascular obstruction, increased blood flow. and high pressure; feeding difficulty, SOB, increased perspiration, increased respiratory infections, fatigue with activity, delayed growth
ventricular septal deficits
pressure in the pulmonary arteries becomes so high that it causes oxygen-poor (blue) blood to flow from the right to left ventricle and then to the body, causing cyanosis. The high pressure also causes the wall of your heart’s right ventricle to thicken (hypertrophy)
Eisenmengers syndrome
decreased pulmonary blood flow characterized by pulmonary valve or artery stenosis, ventricular septal deficits, right ventricle hypertrophy, and override of ventricular septum; central cyanosis, coagulation defects, finger/toe clubbing, feeding difficulty, failure to thrive, dyspnea
Tetralogy of Fallot
mixed pulmonary blood flow characterized by no communication between systemic and pulmonary circulations; result of coexisting congenital transposition of ventricles; cyanosis, CHF, respiratory distress
transposition of great arteries
abnormally slow heart rate (<60 bpm); typically atrioventricular block; may require a pace maker
bradydysrhythmia
abnormally fast heart rate for a child (>200-300 bpm); can lead to CHF; irritability, poor eating habits, palor
tachydysrhythmia
compromised oxygen absorption and carbon monoxide elimination caused by a deficiency of surfactant (produced 34-36 weeks gestation); many recover after a few days and some develop chronic lung conditions
respiratory distress syndrome
airway thickening, formation of excess mucus, and restricted alveolar growth as a result of prolonged use of mechanical ventilation and other traumatic interventions to treat acute respiratory problems; at greater risk for respiratory infections
bronchopulmonary dysplasia
bronchial smooth muscle hyperreactivity that causes airway constriction in the lower respiratory tract, difficulty breathing, and wheezing
asthma
degenerative condition (chromosome 7); muscle-producing glands malfunctioning and producing secretions that are thick, viscous, and lacking in water and block the pancreatic duct, bronchial tree, and digestive tract; abdominal distension, salty-tasting skin, excess sodium levels, greasy/foul stools; can lead to chronic pulmonary disease and enlarged R heart (heart failure)
cystic fibrosis
hematological disorder characterized by too many red blood cells and elevated white blood cells; experienced by 1 in every 150 children with down syndrome
eryhtocytosis or transient leukemia
blood disorder commonly affecting males; characterized by the absence or reduction of one of the clotting blood proteins; longer bleeding time, bleeding episodes, excessive bruising, nosebleeds
hemophilia
severe hemophilia is differentiated because of it’s effect on
joints and muscles
an iron deficiency in the blood treated through diet; may be symptom of lead poisoning, vitamin deficiency, leukemia, and sickle-cell disease
anemia
abnormally shaped red blood cells; common in African-Americans; decreased energy for daily tasks, at risk for organ damage, painful
sickle cell anemia
brittle bones with minor trauma able to cause a fracture; decreased bone deposition from inability to form type I collagen; transmitted by autosomal dominant; range from mild to severe (indicated by age of onset); handling and monitored weight bearing important
osteogenesis imperfecta (OI)
excessive growth at epiphyseal plates; long slender fingers, skull asymmetry, tall stature (joint/eye/heart differences); lax/hypermobile joints and poorly developed striated muscles; walking delayed but otherwise meets developmental milestones
Marfans syndrome (arachondactyly)
‘that MF is tall’
stunting of epiphyseal plate growth and cartilage formation; 4 feet tall or less; short limbs, prominent forehead, small nose and jaw, trunk normal; lumbar lordosis, coxa vara cubitus varas, back/leg pain
achondroplasia (chondrodystrophia/dwarfism)
hip deformity
coxa vara
part of limb deviates to midline of body
cubitus varas
reduced anterior horn cells in the SC; incomplete contracture (fibrous ankylosis) of many joints; thick/spindly extremities, thickened knee/elbow joints; muscles underdeveloped/paralysis; increase ROM and adaptive equipment
arthrogryposis multiplex congenital
fibrous connective tissue process which results in decreased range of motion.
Fibrous ankylosis
