Review Exercise A

Factors that produce a successful pediatric radiographic procedure: tech's attitude and approach to the child, tech's preperation of the room
Possible roles of the parent duing a pediatric procedure: observe, lend support and comfort, serve as a participator, assist w/immobilization, remain in waiting room
Parents should never be in the radiographic room with their child. True/False False, parents can provide comfort to their child in some cases
Battered child syndrome (BCS) is the current term for child abuse. True/False False, NAT (nonaccidental trauma)
The technologist is responsible for reporting potential signs of child abuse to the police. True/False False, the technologist should discuss the facts with the radiologist or supervisor on duty.
The technologist should always use as short an exposure time as possible during pediatric procedures. True/False True
A piece of Plexiglas with short Velcro straps for immobilization of upper and lower limbs. Tam-em Board
A device used to hold down upper or lower limbs without obscuring essential anatomy. Plexiglas hold-down paddle
The immobilization device most commonly used for erect chests and abdomen procedures on infants and small children up to 2 years of age. Pigg-o-stat
Sandbags completely filled with fine sand should be used for a larger pediatric patient. True/False False, course sand is used in sandbags and should not be overfilled; should be pliable.
What size stockinettes are used for immobilization purposes on larger pediatric patients? 4 inch
Which type of tape is not recommended for immobilization purposes on children? Adhesive may create an artifact on the radiograph when placed over the region being radiographed.
What size stockinettes are used for immobilization on smaller pediatric patients? 3 inch
When adhesive tape is used for immobilization of a child, it is placed directly on the skin. True/False False. To prevent injury tape should be twisted so surface is not against the skin or place guaze pads between the skin and tape.
If Ace bandages are used for immobilization of the legs, which size should be used on infants and smaller children? 3, 4, or 6 inch 4 inch
If Ace bandages are used for immobilization of the legs, which size should be used on older children? 3, 4, or 6 inch 6 inch
There are five steps for "mummifying" a child. True/False False, there are six steps.
Primary centers of bone formation (ossification) involving the midshafts of long bones are called: Diaphysis
Secondary centers of ossification of the long bones are called: Epiphysis
The spaces between the primary and secondary areas of ossification are called: Epiphyseal plate
The age a skeleton reaches full ossification is: 25 years old
The approximate age the epiphysis of the fibular apex first becomes clearly visible is: 5 or 6 years old
The safeguards used to help reduce repeat exposures during pediatric procedures. proper immobilization, high mA, short exposure time
The safeguards used to reduce the patient dose during pediatric procedures. close collimation, low dose techniques, minimum number of exposures
Duties of the primary technologist. positions the patient, positions the tube and collimates, instructs the parents
Duties of the assisting technologist. initiates exposures, processes the images, sets exposure factors.
The imaging modality that is most effective in diagnosing pyloric stenosis in children. Sonography
Functional MRI has been used to detect disorders in what conditions? Autism, Tourette syndrome, ADHD
Renal CT scans have largely replaced intravenous urography studies for children. True/False True
Dose can be reduced to the pediatric patient during a CT scan by increasing: kV and pitch ratio
Multiphase CT examinations are necessary for most pediatric studies. True/False False, rarely necessary
What imaging modality is used to diagnose congenital hip dislocations in the newborn, beyond radiography? Sonography
Meconium aspiration may develop during stressful births
Hyaline membrane disease also known as respiratory distress syndrome
Neonate Grave's disease a form of hyperthyroidism
Epiglottitis bacterial infection can lead to closure of the upper airway
Cystic fibrosis inherited disease leading to clogging of bronchi
Croup viral infection leading to labored breathing and dry cough
Hemoptysis coughing up blood
Meningocele congenital defect in which the meninges of the spinal cord protrude through an opening in the vertebral column
Kohler's bone disease inflammation of the navicular bone in the foot
Ewing's osteosarcoma the most common bone cancer in children ages 10-18 years
Talipes equinus congenital deformity of the foot involving plantar flexion
Osteogenesis imperfecta hereditary disorder characterized by soft and fragile bones
Achondroplasia most common form of short-limbed dwarfism
Myelocele congenital defect in which the spinal cord protrudes through and opening in the vertebral column
Osteochondrosis group of diseases affecting the epyphyseal plates of long bones
Hydronephrosis enlarged renal collection system due to obstruction
Pyloric stenosis may result in repeated, forceful vomiting
NEC inflammation of the inner lining of the intestive
Atresias condition characterized by absence of an opening in an organ
Hypospadias congenital defect in male urethra
Hirschsprung disease characterized by absence of rhythmic contractions of large intestive
Celiac disease condition resulting from an allergic reaction to gluten
Skeletal pathologic conditions that require manual exposure factors be increased. hydrocephalus, osteopetrosis
Skeletal pathologic conditions that require manual exposure factors be decreased. idiopathic juvenile osteoporosis, osteochondrosis, osteogenesis imperfecta, osteomalicia
Skeletal pathologic conditions that require no change in manual exposure factors. craniostenosis, developmental dysplasia of hip, osteochondrodysplasias, osteomyelitis, spina bifida, talipes, tumors
Abdominal pathologic conditions that require manual exposure factors be increased. intestinal obstructions: intussusception, meconium ileus, volvulus
Meconium dark, green secretion of the liver and intestinal glands mixed with amniotic fluid
Malignant bone tumors are rare in young children. True/False True. Occur less frequently and are more curable than in adults.
A device with an adjustable type of bicycle seat and two clear plastic body clamps. Pigg-o-stat
